[JBoss JIRA] Created: (ISPN-604) Re-design CacheStore transactions

by Mircea Markus (JIRA)

Re-design CacheStore transactions ---------------------------------- Key: ISPN-604 URL: https://jira.jboss.org/browse/ISPN-604 Project: Infinispan Issue Type: Feature Request Components: Loaders and Stores, Transactions Affects Versions: 4.1.0.CR2, 4.0.0.Final Reporter: Mircea Markus Assignee: Mircea Markus Fix For: 5.0.0.Final Current(4.1.x) transaction implementation in CacheStores is brocken in several ways: 1st problem. - AbstractCacheStore.prepare: public void prepare(List<? extends Modification> mods, GlobalTransaction tx, boolean isOnePhase) throws CacheLoaderException { if (isOnePhase) { applyModifications(mods); } else { transactions.put(tx, mods); } } If this is 1PC we apply the modifications in the prepare phase - we should do it in the commit phase (as JTA does it). 2nd problem. This currently exhibits during commit/rollback with JdbcXyzCacheStore, but it is rather a more general cache store issue. When using a TransactionManager, during TM.commit AbstractCacheStore.commit is being called internally which tries to apply all the modifications that happened during that transaction. Within the scope of AbstractCacheStore.commit, JdbcStore obtains a connection from a DataSource and tries to write the modifications on that connection. Now if the DataSource is managed (e.g. by an A.S.) on the DS.getConnection call the A.S. would try to enlist the connection with the ongoing transaction by calling Transaction.enlistResource(XAResource xaRes) [1] This method fails with an IllegalStateException, because the transaction's status is preparing (see javax.transaction.Transaction.enlistResource). Suggested fix: - the modifications should be registered to the transaction as they happen(vs. during prepare/commit as it happens now) - this requires API changes in CacheStore, e.g. void store(InternalCacheEntry entry) should become void store(InternalCacheEntry entry, GlobalTransaction gtx) (gtx would be null if this is not a transactional call). [1] This behavior is specified by the JDBC 2.0 Standard Extension API, chapter 7 - distributed transaction -- 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-503) collate keys in replication queue

by Mircea Markus (JIRA)

collate keys in replication queue ---------------------------------- Key: ISPN-503 URL: https://jira.jboss.org/browse/ISPN-503 Project: Infinispan Issue Type: Feature Request Components: Core API Affects Versions: 4.1.0.BETA2 Reporter: Mircea Markus Assignee: Manik Surtani At the moment the replication queue is replicating all the keys. What it can do is to collate them, similar to the way cache stores are collating writes. E.g. 1. put(k,v1) 2. put(k,v2). This can be collated in put(k,v2), as put(k,v1) is redundant. This would optimize async replication in a way that cannot be handled by jgroups. -- 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-159) Extended coalesced logic to other parts

by Galder Zamarreno (JIRA)

Extended coalesced logic to other parts --------------------------------------- Key: ISPN-159 URL: https://jira.jboss.org/jira/browse/ISPN-159 Project: Infinispan Issue Type: Feature Request Components: RPC, Transactions Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 4.0.0.CR1 Reuse same coalesced async cache store logic to: - Reduce size of replicable commands where N modifications are sent so that only latest state is sent. - Manage the async replication queue. -- 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-330) Separate scheduled/unscheduled async cache store configuration

by Galder Zamarreno (JIRA)

Separate scheduled/unscheduled async cache store configuration -------------------------------------------------------------- Key: ISPN-330 URL: https://jira.jboss.org/jira/browse/ISPN-330 Project: Infinispan Issue Type: Sub-task Components: Configuration, Loaders and Stores Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 4.1.0.BETA1 Implement configuration that allows differentiation between scheduled/unscheduled strategies: <async enabled="true"> <scheduled frequency="1000" /> </async> <async enabled="true"> <unscheduled poolsize="50" /> </async> This format allows for easier extension of properties in scheduled/unscheduled modes. -- 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-1103) Soft schema-based storage

by Manik Surtani (JIRA)

Soft schema-based storage ------------------------- Key: ISPN-1103 URL: https://issues.jboss.org/browse/ISPN-1103 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 JIRA is about storing metadata alongside values. Perhaps encapsulating values as SchematicValues, which could be described as: {code} class SchematicValue { String jsonMetadata; String jsonObject; } {code} Metadata would allow for a few interesting features: * Extracting of lifespan and timestamp data if manipulated over a remote protocol (REST, HotRod, etc) * Content type for REST responses * Timestamps for REST headers, will affect HTTP content caches * Validation information (may not be processed by Infinispan, but can be used by client libs) * Classloader/marshaller/classdef version info * General structure of the information stored -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (ISPN-939) Index corruption when remote node dies during commit

by Tristan Tarrant (JIRA)

Index corruption when remote node dies during commit ---------------------------------------------------- Key: ISPN-939 URL: https://issues.jboss.org/browse/ISPN-939 Project: Infinispan Issue Type: Bug Components: Lucene Directory Affects Versions: 4.2.1.CR2 Reporter: Tristan Tarrant Assignee: Sanne Grinovero Using a scenario similar to the one described in ISPN-909: Infinispan: 3 caches: lockCache (replicated, volatile, no eviction), metadataCache (replicated, persisted, no eviction), dataCache (distributed, persisted, eviction, hash numOwners=2) Node 1: coordinator, IndexWriter open constantly and writing a stream of documents, committing after each one Node 2: opens a read-only IndexReader to perform queries, using reopen to keep in sync with the updates coming from node 1 If we "kill -9" node 2 (to simulate a crash), we get a SuspectException in node 1 during the pre-commit phase (within IndexWriter.commit()). Catching the Throwable we then close() the writer but from then on we get "Read past EOF" errors when trying to access the index (both with readers and writers). -- 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.
