Re: [hibernate-dev] HHH-6726 LONG and LONG RAW column types in Oracle
by Łukasz Antoniak
Currently Oracle supports database versions from 10.1 to 11.2 [1]. LONG
and LONG RAW data types are deprecated since version 8 and 8i (released
before September 2000) [2]. Oracle keeps those column types only for
backward compatibility [3].
I tried the following scenario (Oracle 10gR2):
1. Create schema with "hibernate.hbm2ddl.auto" set to "create". The LONG
column is created.
2. Insert some data.
3. Modify Oracle dialect as Gail suggested. Avoid setting
"hibernate.hbm2ddl.auto".
4. Insert some data.
To my surprise the test actually passed :). However, I think that we
cannot guaranty the proper behavior in every situation.
As for performance, ImageType is extracted by calling
ResultSet.getBytes() method, which fetches all data in one call [4]. I
don't suppose a major performance difference when data is streamed in
another call. oracle.jdbc.driver.LongRawAccessor.getBytes also fetches
data by reading the stream.
The bug reading LONG column affects JDBC drivers since version 10.2.0.4.
I think that we have to choose between:
- changing Oracle10gDialect. Make a not about it in migration guide to
4.0 and update "5.2.2. Basic value types" chapter in Hibernate
documentation.
- introducing Oracle11gDialect. It can sound weird to access Oracle 10g
database with Oracle 11g dialect.
- disabling execution of Hibernate tests that fail because of this issue
with @SkipForDialect (and maybe develop another version of them with
CLOBs and BLOBs, @RequiresDialect). Hibernate is written correctly
according to "Default Mappings Between SQL Types and Java Types"
(referenced earlier by Gail) and this is more Oracle's JDBC
implementation issue. This option came to my mind, but it's weird :P.
I would vote for the first option.

Configuration to support batching (or sorting) of DELETE statements efficiently
by Madhusudana Reddy Sunnapu
Hi,
Hibernate provides simple configuration properties to enable batch inserts
and updates using "hibernate.order_inserts" and "hibernate.order_updates"
respectively. These setting allow hibernate to sort the insert and update
statements and process them in batches efficiently.
But we don't have such a configuration to sort or batch delete statements
efficiently. Especially with CascadeType.DELETE we can see that delete
statements are not batched effectively and could result in extra network
calls to the database for deletion.(Refer:
http://vladmihalcea.com/2015/03/26/how-to-batch-delete-statements-with-hi...
)
So I am thinking wouldn't it be a good feature to have hibernate support
similar configuration, say "hibernate.order_deletes", to enable batch
deletes similar to updates and inserts.
Cheers,
Madhu.

Re: [hibernate-dev] [hibernate-orm] HHH-7572 - Develop API for load-by-multiple-ids (#1136)
by Konstantin Bulanov
Hello Steve, as you asked moving our discussion about HHH-7572 in dev mail
list.
Regarding you question, in current architecture and implementation we have
the following point to perform entity persistence customization.
Annotation:
https://docs.jboss.org/hibernate/orm/5.0/javadocs/org/hibernate/annotatio...
which allows us to specify our own implementation of
https://docs.jboss.org/hibernate/orm/5.0/javadocs/org/hibernate/persister....
One of its methods is:
Object load(Serializable id,
Object optionalObject,
LockMode lockMode,
SessionImplementor session)
throws HibernateException
Load an instance of the persistent class.
and
Object load(Serializable id,
Object optionalObject,
LockOptions lockOptions,
SessionImplementor session)
throws HibernateException
Load an instance of the persistent class.
These two methods allows to specify you own Loader implementation to load
Entity by IDS,
in mentioned issue this part of contract was ignored by changing call
sequence on loading by multiple ids.
By Single id;
org.hibernate.internal.SessionImpl#get->IdentifierLoadAccessImpl->org.hibernate.internal.SessionImpl.IdentifierLoadAccessImpl#load->org.hibernate.event.spi.LoadEventListener#onLoad->org.hibernate.event.internal.DefaultLoadEventListener#loadFromDatasource->org.hibernate.persister.entity.EntityPersister#load
By Multiple id:
org.hibernate.internal.SessionImpl#byMultipleIds->org.hibernate.internal.SessionImpl.MultiIdentifierLoadAccessImpl#multiLoad->org.hibernate.loader.entity.DynamicBatchingEntityLoaderBuilder#multiLoad
So in new API for multiple load we lose at least 2 possible extension
points: onLoadEvent, Persister.load (here we could customize loader -
specify our own instead hardcoded one)
>From my point of view there should be the same approach to get entities by
ID(independent multiple or single).
So which one approach is correct and future-proof for Single id or Multiple
Ids?

HHH-8076 - CDI-capable entity listeners
by Steve Ebersole
As part of the work on HHH-8076 for ORM 5.1 I am going to have to change
up, in some fashion, some or all of the following internal/spi contracts :
* org.hibernate.jpa.event.spi.jpa.Callback
* org.hibernate.jpa.event.spi.jpa.CallbackRegistry
* org.hibernate.jpa.event.spi.jpa.ListenerFactory
* org.hibernate.jpa.event.internal.jpa.CallbackProcessor
I need to know whether any integrations either use any of these or provide
custom impls for any of them.

HHH-9993 - IsolationDelegate + no-Connection
by Steve Ebersole
HHH-9993[1] is a request to extend IsolationDelegate to cater for
transaction hooks which do not need access to a JDBC Connection.
A quick primer for those unfamiliar, IsolationDelegate is a contract to
allow work to be done in a fashion that makes sure it is isolated from the
main Session transaction. We have implementations of this to fit JTA and
JDBC scenarios. Additionally, it allows to indicate that the isolated work
should itself be transacted or not. In the JDBC-transaction scenario
(which HHH-9993 deals with) transacted-isolated work is achieved by passing
in a separate Connection to use since that is the only way to achieve a new
transaction in JDBC (JDBC has no "suspend/resume" transaction
functionality).
HHH-9993 is again about this isolated, transacted scenario under the
JDBC-transaction handling. Specifically for hibernate-infinispan call
backs there is no need to obtain the second Connection. So HHH-9993 is
about reducing the overhead of this call by allowing it a way to say "I
need to do some isolated, transacted work but I do not need the Connection".
For this particular use case that is fine: hibernate-infinispan will never
access the Connection. I do worry however about this general use-case. My
concern is specifically that some use cases will attempt to call back into
the Session. At the moment we do not "protect" against that.
I'd like to get some opinions on this.
