[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-1090) Hot Rod protocol improvements for version 2

by Galder Zamarreño (JIRA)

Hot Rod protocol improvements for version 2 ------------------------------------------- Key: ISPN-1090 URL: https://issues.jboss.org/browse/ISPN-1090 Project: Infinispan Issue Type: Enhancement Components: Cache Server Reporter: Galder Zamarreño Assignee: Galder Zamarreño Fix For: 5.1.0.BETA1, 5.1.0.Final This JIRA will act as a place to keep track of enhancements to the Hot Rod protocol that should be included in version 2 of the protocol: - We need a new error status code so that clients can detect when a node has been suspected and so react accordingly (i.e. not bubble it up but instead failover). Currently, this can be solved by checking whether the error message contains SuspectException but this is not nice. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (ISPN-848) Enhance HotRod to allow explicit locking of keys

by Erik Salter (JIRA)

Enhance HotRod to allow explicit locking of keys ------------------------------------------------ Key: ISPN-848 URL: https://issues.jboss.org/browse/ISPN-848 Project: Infinispan Issue Type: Feature Request Reporter: Erik Salter Assignee: Manik Surtani Hot Rod clients should allow explicit locking of keys, especially useful for the "find-for-update" design pattern. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] (ISPN-1457) replay prepare if it fails

replay prepare if it fails -------------------------- Key: ISPN-1457 URL: https://issues.jboss.org/browse/ISPN-1457 Project: Infinispan Issue Type: Enhancement Components: Transactions Affects Versions: 5.0.0.FINAL Reporter: Mircea Markus Assignee: Manik Surtani Fix For: 5.1.0.FINAL Attachments: AbstractCrashTest.java If the prepare fails for whatever reasons the system should automatically try to replay it - the user code would do the same thing.

[JBoss JIRA] (ISPN-1539) Optimisation: reduce the number of RPCs when L1 is enabled (default)

by Mircea Markus (Created) (JIRA)

Optimisation: reduce the number of RPCs when L1 is enabled (default) -------------------------------------------------------------------- Key: ISPN-1539 URL: https://issues.jboss.org/browse/ISPN-1539 Project: Infinispan Issue Type: Feature Request Affects Versions: 5.0.1.FINAL Reporter: Mircea Markus Assignee: Mircea Markus Fix For: 5.1.0.CR1 cache.put(k,v) does a remote get(1st RPC) and an put(2nd RPC) to the same remote node. This can be merged into a single RPC. -- This message is automatically generated by JIRA.

[JBoss JIRA] (ISPN-1543) Split CacheImpl into TransactionalCache and NonTransactionalCache

by Mircea Markus (Created) (JIRA)

Split CacheImpl into TransactionalCache and NonTransactionalCache ------------------------------------------------------------------ Key: ISPN-1543 URL: https://issues.jboss.org/browse/ISPN-1543 Project: Infinispan Issue Type: Feature Request Components: Core API Affects Versions: 5.1.0.BETA4 Reporter: Mircea Markus Assignee: Mircea Markus Priority: Minor Fix For: 5.1.0.FINAL There is a lot of unnecessary complexity in CacheImpl caused by handling two types of caches: transactional and non-transactional. This code (and potentially InvocationContextContainer) can be simplified a lot by splitting the logic into two cache implementations: TransactionalCache and NonTransactionalCache. The common logic would be moved in an AbstractCache. -- This message is automatically generated by JIRA.

[JBoss JIRA] (ISPN-1988) coalesce same key writes within a transaction

by Mircea Markus (JIRA)

Mircea Markus created ISPN-1988: ----------------------------------- Summary: coalesce same key writes within a transaction Key: ISPN-1988 URL: https://issues.jboss.org/browse/ISPN-1988 Project: Infinispan Issue Type: Feature Request Components: Transactions Affects Versions: 5.1.4.FINAL Reporter: Mircea Markus Assignee: Mircea Markus Fix For: 5.2.0.FINAL Following code run with optimistic caches: start tx put k, v1 put k, v2 put k, v3 commit Would cause the PrepareCommand that is sent around to contain 3 PutKeyvalueCommands which is sub-optimal. What we can do is to only send the last written value (i.e. k v3) and ignore the previous two (reuse the code in AsyncCacheStore). Besides reducing the payload, from this would benefit the AtomicHashMaps which uses this code quite a lot and also the OptimisticLockingInterceptor which would not attempt to order the keys. I guess this should be a feature that is disabled by default, as I don't think it is required in general. Might as well be not configurable, enabled by default feature.

[JBoss JIRA] Created: (ISPN-1116) Version-aware InternalCacheEntries

by Manik Surtani (JIRA)

Version-aware InternalCacheEntries ---------------------------------- Key: ISPN-1116 URL: https://issues.jboss.org/browse/ISPN-1116 Project: Infinispan Issue Type: Feature Request Components: Core API Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 5.1.0.BETA1, 5.1.0.Final This is to support a number of things including eventual consistency as well as tombstones for deleted entries. Further, this version would need to be used when doing MVCC concurrent write comparisons for write skews (and not just a reference check which is done at the moment). This also would need to be able to use versions provided in a value's metadata (see ISPN-1103) -- This message is automatically generated by JIRA.
