[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-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

[JBoss JIRA] Created: (ISPN-586) ManagedConnectionPool doesn't work in a transactional context

by Manik Surtani (JIRA)

ManagedConnectionPool doesn't work in a transactional context ------------------------------------------------------------- Key: ISPN-586 URL: https://jira.jboss.org/browse/ISPN-586 Project: Infinispan Issue Type: Bug Components: Loaders and Stores, Transactions Affects Versions: 4.1.0.CR2 Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 4.1.0.CR3 >From the reporter: "Anyways, what seems to be the real problem is that all the things that need to be persisted are saved in memory and then when the transaction is completing (either in prepare or commit phase) the loader attempts to get a connection from the datasource. Apparently this is illegal and throws an exception which is what causes the HeuristicMixedException further up the chain. This only fails when using a ManagedConnectionFactory. If I swap out a PooledConnectionFactory it works fine. I presume the managed version fails because it returns the same connection that is part of the active transaction for that thread and you can't perform new operations on that connection once the transaction is already in prepare or commit. This feels like a bit of a design flaw to me... I didn't see an obvious fix." This possibly has to do with the AbstractCacheStore doing the following in prepare(): " public void prepare(List<? extends Modification> mods, GlobalTransaction tx, boolean isOnePhase) throws CacheLoaderException { if (isOnePhase) { applyModifications(mods); } else { transactions.put(tx, mods); } } " and later during commit actually writing the changes to the store. This generic, "abstract" behaviour is intended for non-transactional data stores (such as a filesystem). Behaviour should be different when it comes to transactional data stores. -- 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
