Map/Reduce over HotRod ---------------------- Key: ISPN-1094 URL: https://issues.jboss.org/browse/ISPN-1094 Project: Infinispan Issue Type: Feature Request Components: Cache Server Reporter: Galder Zamarreño Assignee: Manik Surtani Map/Reduce over HotRod. Most probably we'll settle on portable javascript code to be executable remotely. More info in the discussion thread. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (ISPN-1284) change default tx enlistment

by Mircea Markus (JIRA)

change default tx enlistment ---------------------------- Key: ISPN-1284 URL: https://issues.jboss.org/browse/ISPN-1284 Project: Infinispan Issue Type: Feature Request Components: Configuration, Transactions Affects Versions: 5.0.0.CR8 Reporter: Mircea Markus Assignee: Mircea Markus Fix For: 5.1.0.ALPHA1, 5.1.0.FINAL ATM transactions are being enlisted as XAResources with recovery disabled. XAResource enlistment *without* recovery does not bring any benefit over Synchronization enlistment, which is more efficient(30-40%): http://infinispan.blogspot.com/2011/06/transactions-enhancements-in-50.html So the suggested enlistment should be Synchronization (default). Also if xa-enlistment is preferred then recovery should be enabled by default - there's little reason in using XAResource enlistment without recovery. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (ISPN-1409) Introduce a binary-stream upgrading CacheLoader

by Sanne Grinovero (JIRA)

Introduce a binary-stream upgrading CacheLoader ----------------------------------------------- Key: ISPN-1409 URL: https://issues.jboss.org/browse/ISPN-1409 Project: Infinispan Issue Type: Feature Request Reporter: Sanne Grinovero Assignee: Manik Surtani Fix For: 5.1.0.BETA1 We need a CacheLoader decorator able to chain sets of two different Externalizers which are targeting the same Java type to transform from one binary format to the next binary format. Example: a Person object stored in the cache and an Externalizer is coupled to it. In a new release the Externalizer is changed to provide a different binary representation. Using the old one the stream is transformed from a byte[] to a Person, then this Java instance is feed to the new Externalizer implementation to get the new corresponding byte[]; the updated stream is stored in the decorated CacheLoader so that the nodes going to be attached to the cache store and using the new Externalizer will be fine. A little complexity is introduced if the cache has to know about different sets of Externalizers if several different types need to be upgraded. A possible solution is to use a single decorator instance for each type, creating a chain of decorators if they are able to pass "as is" each externalizer id they are not directly coupled to. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (ISPN-1141) BigMemory Direct buffer

by Magnus Magnus (JIRA)

BigMemory Direct buffer ----------------------- Key: ISPN-1141 URL: https://issues.jboss.org/browse/ISPN-1141 Project: Infinispan Issue Type: Enhancement Components: Distributed Cache Reporter: Magnus Magnus Assignee: Manik Surtani It should be configurable if data stored by NIO buffer or not. It means data stored outside of java heap. Create, destroy in the external memory should be managed by infinispan. With this solution gc can run fast however infinispan node can handle huge amount of memory. In the current case the optional size of the java memory of a node is smaller or equals than 4GB because of garbage collection issues above 4GB. See a similar thing in EHCache BigMemory. http://www.snoopal.com/documents/GaSovOTchHCsOF5X7bG691/-Scale-over-the-l... 12nd page -- This message is automatically generated by JIRA.

[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.

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
