[JBoss JIRA] Created: (ISPN-557) support for same transaction touching multiple nodes (multiple VMs)

by Mircea Markus (JIRA)

support for same transaction touching multiple nodes (multiple VMs) -------------------------------------------------------------------- Key: ISPN-557 URL: https://jira.jboss.org/browse/ISPN-557 Project: Infinispan Issue Type: Feature Request Components: Transactions Reporter: Mircea Markus Assignee: Manik Surtani Fix For: 5.1.0.Final E.g. if a distributed transaction managers touches two embedded Infinispan nodes within the same transaction. Could be implemented using the Hot Rod client approach - but in an embedded fashion! EmbeddedClient <-- implements logic above Except comms are in-VM for local entries And via RpcDispatcher for remote entries RemoteClient extends EmbeddedClient Adds proper HotRod layer for comms Including failover, smart routing, etc. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-374) Add event handling to Hot Rod

by Galder Zamarreno (JIRA)

Add event handling to Hot Rod ----------------------------- Key: ISPN-374 URL: https://jira.jboss.org/jira/browse/ISPN-374 Project: Infinispan Issue Type: Feature Request Components: Cache Server Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 5.1.0.BETA1, 5.1.0.Final Enable Hot Rod servers to send events asynchronously to registered clients over persistent connections. This would allow use cases such as clients maintaining L1 caches and these events could be used for servers to invalidate keys on the client side.

[JBoss JIRA] Created: (ISPN-387) Enable accessing Hot Rod servers via WebSockets

by Galder Zamarreno (JIRA)

Enable accessing Hot Rod servers via WebSockets ----------------------------------------------- Key: ISPN-387 URL: https://jira.jboss.org/jira/browse/ISPN-387 Project: Infinispan Issue Type: Feature Request Components: Cache Server Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 5.1.0.BETA1, 5.1.0.Final Add a flag to Hot Rod server configuration so that appropiate Base64 encoder/decoder can be used when interfacing with WebSocket clients. This might also require for Netty WebSocket channel handlers to be set up so that WebSocket upgrade handshaking can be dealt with independent of Hot Rod. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-78) Large object support

by Manik Surtani (JIRA)

Large object support -------------------- Key: ISPN-78 URL: https://jira.jboss.org/jira/browse/ISPN-78 Project: Infinispan Issue Type: Feature Request Components: Core API Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 5.0.0.GA if each VM is allocated a 2GB heap and you have a 100 nodes in a grid with 1 redundant copy for each key, you have a theoretical addressable heap of 100GB. But you are limited by (half) the heap of a single VM per entry, since entries are stored whole. E.g., cache.put(k, my2GBObject) will fail since you need at least 2GB for the object + another 2GB for its serialized form. This gets worse when you try cache.put(k, my10GBObject). This *should* be possible if we have a theoretical 100GB heap. Potential solutions here are to fragment large objects, and store each fragment under separate keys. Another approach would be to directly stream objects to disk. etc. Needs thought and design, possibly a separate API to prevent 'pollution" of the more simplistic API. (JumboCache?) Re: fragmenting, issues to overcome: How many chunks to fragment into? Max size of each key could be configured, but how do we determine the size of an Object? VM instrumentation? Or perhaps the JumboCache only stores byte[]'s? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-686) JdbcStringBasedCacheStore loads previous data from store before an insert

by Sanne Grinovero (JIRA)

JdbcStringBasedCacheStore loads previous data from store before an insert ------------------------------------------------------------------------- Key: ISPN-686 URL: https://jira.jboss.org/browse/ISPN-686 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Affects Versions: 4.2.0.ALPHA2, 4.1.0.Final, 4.0.0.Final Reporter: Sanne Grinovero Assignee: Manik Surtani Fix For: 4.2.0.Final, 5.0.0.Final The JdbcStringBasedCacheStore implementation loads the previous data on an insert to find out if it should generate an UPDATE or INSERT statement, while it would perform much better to just verify if the primary key exists. On top of this, some databases provide ways to avoid the need to check at all, like MySQL's " INSERT ... ON DUPLICATE KEY UPDATE" [http://dev.mysql.com/doc/refman/5.0/en/insert-on-duplicate.html] -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-800) Infinispan inside OSGI

by luca stancapiano (JIRA)

Infinispan inside OSGI ---------------------- Key: ISPN-800 URL: https://jira.jboss.org/browse/ISPN-800 Project: Infinispan Issue Type: Feature Request Components: Core API Affects Versions: 4.2.0.CR1 Reporter: luca stancapiano Assignee: Manik Surtani We need to import infinispan inside a OSGI repository. Tests are made with Felix. I added the configuration to use infinispan inside a osgi repository. We need to ignore all listed dependencies. With this configuration we can install infinispan-core.jar inside OSGI. Its achievement will be as a base installation here: https://github.com/flashboss/infinispan I added the Import-Package because you are forced to put manually in Felix all dependencies as jgroups, jboss marshalling, jcip, all apache commons. I've seen infinispan core working by default without all those libraries, so I think the same achievement should be replicated in OSGI. Inside the Import-Package tag I excluded those libraries so Infinispan core can be started in default mode without errors. If we want use the replication in OSGI, it is enough add manually the other packages (jgroups.jar etc etc) Actually the core bundle can be installed. But to be used it needs theese projects be installed as osgi bundles: jboss transaction api 1.0.1.GA (It is not yet a OSGI bundle. Waiting for a response to: https://jira.jboss.org/browse/JBEE-67) jgroups 2.10.1.GA (fixed in jgroups 1.12) river 1.2.3.GA marshalling-api 1.2.3.GA jboss common core 2.2.14.GA jboss logging spi 2.0.5.GA rhq plugin annotations 1.4.0.B01 i18nlog 1.0.9 log4j 1.2.16 We should make sure proper 'Import-Package' property is specified in the MANIFEST.MF so that: 1- it fails to load obviously when there's any missing bundles that are essential in using the very core functionality of Infinispan. 2 - it does not fail due to the dependency that is not really essential. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-375) Enable Hot Rod clients to start transactions

by Galder Zamarreno (JIRA)

Enable Hot Rod clients to start transactions -------------------------------------------- Key: ISPN-375 URL: https://jira.jboss.org/jira/browse/ISPN-375 Project: Infinispan Issue Type: Feature Request Components: Cache Server Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 5.1.0.BETA1, 5.1.0.Final It might be useful to allow Hot Rod clients to start transactions within Hot Rod servers. The possibility of clients participating in the actual transaction, i.e. being an XAResource, should not be imposed since this might be less than trivial to achieve in non-Java environments. The alternative would be to allow clients to start Hot Rod server local transactions only. This would require enhancing Hot Rod spec to have some begin/commit/rollback commands that return a tx id, and for clients to be able to send this id as part of each command that should participate in the transaction. Pitfalls to avoid include avoiding a transaction to be propagated over several Hot Rod servers. IOW, to simplify things, if a tx is started in server A, all ops within that tx should be directed to tx. Load balancing could still happen but would need to be tx sticky. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
