The main difference is that we're providing connectivity information for multiple datasources, + and we're + also describing our desired sharding behavior via a + <classname>ShardStrategyFactory</classname>. Let's look at some sample configuration code for our weather + report application, which we're going to run with 3 shards. + <programlisting><![CDATA[ +1 public SessionFactory createSessionFactory() { +2 Configuration prototypeConfig = new Configuration().configure("shard0.hibernate.cfg.xml"); +3 prototypeConfig.addResource("weather.hbm.xml"); +4 List<Configuration> shardConfigs = new ArrayList<Configuration>(); +5 shardConfigs.add(new Configuration().configure("shard0.hibernate.cfg.xml"); +6 shardConfigs.add(new Configuration().configure("shard1.hibernate.cfg.xml"); +7 shardConfigs.add(new Configuration().configure("shard2.hibernate.cfg.xml"); +8 ShardStrategyFactory shardStrategyFactory = buildShardStrategyFactory(); +9 ShardedConfiguration shardedConfig = new ShardedConfiguration( +10 prototypeConfig, +11 shardConfigs, +12 shardStrategyFactory); +13 return shardedConfig.buildShardedSessionFactory(); +14 } +15 +16 ShardStrategyFactory buildShardStrategyFactory() { +17 ShardStrategyFactory shardStrategyFactory = new StrategyFactory() { +18 public ShardStrategy newShardStrategy(List shardIds) { +19 RoundRobinShardLoadBalancer loadBalancer = new RoundRobinShardLoadBalancer(shardIds); +20 ShardSelectionStrategy pss = new RoundRobinShardSelectionStrategy(loadBalancer); +21 ShardResolutionStrategy prs = new AllShardsShardResolutionStrategy(shardIds); +22 ShardAccessStrategy pas = new SequentialShardAccessStrategy(); +23 return new ShardStrategyImpl(pss, prs, pas); +24 } +25 } +26 return shardStrategyFactory; +27 } + ]]></programlisting> + </para> + <para> + So what's going on here? First, you'll notice that we're actually allocating four + <classname>Configurations</classname>. The first <classname>Configuration</classname> + we allocate (line 2) is the prototype <classname>Configuration</classname>. The + <classname>ShardedSessionFactory</classname> + we eventually construct (line 13) will contain references to 3 standard + <classname>SessionFactory</classname> objects. Each of these 3 standard + <classname>SessionFactory</classname> objects will have been constructed from the prototype configuration. The + only attributes that will differ across these standard <classname>SessionFactory</classname> + objects are: + <itemizedlist mark="opencircle"> + <listitem> + <para>connection.url</para> + </listitem> + <listitem> + <para>connection.user</para> + </listitem> + <listitem> + <para>connection.password</para> + </listitem> + </itemizedlist> + The three <classname>Configuration</classname> objects we're loading (lines 5 - 7) will be consulted for the + shard-specific database url, database user, and database password, and that's all. This means that if you change the + connection pool parameters in shard1.hibernate.cfg.xml, those parameters will be ignored. If you add another + mapping file to the <classname>Configuration</classname> + loaded with the properties defined in weather2.hibernate.cfg.xml, that mapping will be ignored. + With the exception of the properties listed above, the configuration of our shard-aware + <classname>SessionFactory</classname> comes entirely from the prototype + <classname>Configuration</classname>. This may seem a bit strict, but the sharding code + needs to assume that all shards are identically configured. + </para> + <para> + If you're looking at this code and thinking it seems a bit silly to provide fully-formed configuration + documents that, save a couple special properties, are ignored, rest assured we've looked at this code and + thought the same thing. We expect the configuration mechanism to evolve over time. We picked this particular + mechanism because it allowed the greatest reuse of configuration code that was already available in + Hibernate Core. + </para> + <para> + Once we've built our <classname>Configuration</classname> + objects we need to put together a <classname>ShardStrategyFactory</classname> + (line 8). A <classname>ShardStrategyFactory</classname> + is an object that knows how to create the 3 types of strategies that programmers can use to control the sharding + behavior of the system. For more information on these strategies please see the chapters titled Sharding Strategies. + </para> + <para> + Once we've instantiated our <classname>ShardStrategyFactory</classname> we can construct a + <classname>ShardedConfiguration</classname> (line 9), and once we've constructed + our <classname>ShardedConfiguration</classname> we can ask it to create a + <classname>ShardedSessionFactory</classname> (line 13). It's important to note that + <classname>ShardedSessionFactory</classname> extends <classname>SessionFactory</classname>. This means we can return a standard + <classname>SessionFactory</classname> (line 1). Our application's Hibernate code doesn't need + to know that it's interacting with sharded data. + </para> + <para> + Now let's take a look at the configuration and mapping files that we loaded in. You'll definitely recognize + them, but there are a few key additions and modifications related to sharding. + <programlisting><![CDATA[ + 1  + 2 <hibernate-configuration> + 3 <session-factory name="HibernateSessionFactory0">  + 4 <property name="dialect">org.hibernate.dialect.MySQLInnoDBDialect</property> + 5 <property name="connection.driver_class">com.mysql.jdbc.Driver</property> + 6 <property name="connection.url">jdbc:mysql://localhost:3306/mydb</property> + 7 <property name="connection.username">my_user</property> + 8 <property name="connection.password">my_password</property> + 9 <property name="hibernate.connection.shard_id">0</property>  + 10 <property name="hibernate.shard.check_all_associated_objects_for_different_shards">true</property>  + 11 </session-factory> + 12 </hibernate-configuration> + ]]></programlisting> + <programlisting><![CDATA[ + 1  + 2 <hibernate-configuration> + 3 <session-factory name="HibernateSessionFactory1">  + 4 <property name="dialect">org.hibernate.dialect.MySQLInnoDBDialect</property> + 5 <property name="connection.driver_class">com.mysql.jdbc.Driver</property> + 6 <property name="connection.url">jdbc:mysql://localhost:3306/mydb</property> + 7 <property name="connection.username">my_user</property> + 8 <property name="connection.password">my_password</property> + 9 <property name="hibernate.connection.shard_id">1</property>  + 10 <property name="hibernate.shard.check_all_associated_objects_for_different_shards">true</property>  + 11 </session-factory> + 12 </hibernate-configuration> + ]]></programlisting> + We'll skip the contents of weather2.hibernate.cfg.xml because the pattern should by now be obvious. We're + giving each session factory a unique name via the name attribute of the session-factory element, and we're + also giving each session factory a shard id. This is required. If you try to configure a + <classname>ShardedSessionFactory</classname> with a <classname>Configuration</classname> + object that does not have a shard id you'll get an error. At the moment we require that the shard id of one + of your session factories be 0. Beyond that, the internal representation of a shard id is a + <classname>java.lang.Integer</classname> so all values within that range are legal.

Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + +[This is the first released version of the Lesser GPL. It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded.

Sometimes you have a distributed deployment architecture +(network latency between California and India might be too high to have a single database). There might +even be non-technical reasons (a potential customer simply won't do the deal unless her company's data lives in its +own db instance). Whatever your reasons, talking to multiple relational databases inevitably complicates +the development of your application.
