[JBoss JIRA] (ISPN-2017) Allow a org.jboss.marshalling.ClassTable to be specified in SerializationConfigurationBuilder

by Stuart Douglas (JIRA)

Stuart Douglas created ISPN-2017: ------------------------------------ Summary: Allow a org.jboss.marshalling.ClassTable to be specified in SerializationConfigurationBuilder Key: ISPN-2017 URL: https://issues.jboss.org/browse/ISPN-2017 Project: Infinispan Issue Type: Feature Request Components: Marshalling Affects Versions: 5.1.4.FINAL Reporter: Stuart Douglas Assignee: Galder Zamarreño This would allow AS7 to provide a ClassTable implementation that would mean we would not need to serialise the full class name and module for some common AS7 classes that are present in session replication (namely org.jboss.as.clustering.web.DistributableSessionMetadata, org.jboss.as.clustering.SimpleMarshalledValue and org.infinispan.context.Flag). -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (ISPN-999) Support eventual consistency

by Manik Surtani (JIRA)

Support eventual consistency ---------------------------- Key: ISPN-999 URL: https://issues.jboss.org/browse/ISPN-999 Project: Infinispan Issue Type: Feature Request Components: Distributed Cache, Locking and Concurrency Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 5.1.0.BETA1, 5.1.0.Final Essentially, it is about supporting eventual consistency in Infinispan. Currently Infinispan is strongly consistent when using synchronous distribution mode. Each data owner receives updates synchronously so anyone anywhere on the cluster doing a GET will see the correct value. The only exception is during a rehash (when a new node joins or leaves), that consistency is eventual since the GET may reach a new joiner who may not have applied state it receives from its neighbours yet. However this is hidden from users since the GET is sent to> 1 data owner and if an UnsureResponse is received (determined by the fact that a new joiner responds and the new joiner wouldn't have finished applying state), the caller thread waits for more definite responses. However, there is a use case for being eventually consistent as well: the main benefits being speed and partition tolerance. E.g., if we use distribution in asynchronous mode, the writes become *much* faster. However, anyone anywhere doing a GET will have to perform the GET on all data owners, and compare the versions of the data received to determine which is the latest. And if there is a conflict, to pass back all values to the user. So in terms of design, what I have in mind is: * All cache entries are versioned using vector clocks. One vector clock per node. * When a node performs a GET, the GET is sent to all data owners (concurrently), and the value + version is retrieved from each. * If the versions are all the same (or they can be "fast forwarded"), the value is returned * Otherwise, all potential values and their versions are returned * A resolve() API should be provided where application code may provide a "hint" as to which version should be "correct" - which will cause an update. * In terms of implementation, this will touch the DistributionInterceptor, InternalCacheEntry and relevant factories, some config code (since this should be consistency model should be configurable), and a new public interface. -- This message is automatically generated by JIRA.

[JBoss JIRA] (ISPN-1924) Switch Infinispan internals to use new configuration

by Galder Zamarreño (JIRA)

Galder Zamarreño created ISPN-1924: -------------------------------------- Summary: Switch Infinispan internals to use new configuration Key: ISPN-1924 URL: https://issues.jboss.org/browse/ISPN-1924 Project: Infinispan Issue Type: Task Components: Configuration Reporter: Galder Zamarreño Assignee: Galder Zamarreño Fix For: 5.2.0.ALPHA1, 5.2.0.FINAL This avoids reliance on old configuration and avoids the need to add new options to old configuration. I had originally planned to do this as part of ISPN-1367 but it's better splitted out. -- This message is automatically generated by JIRA.

[JBoss JIRA] (ISPN-1997) JDBC test suite fails with recent H2 driver

by Tristan Tarrant (JIRA)

Tristan Tarrant created ISPN-1997: ------------------------------------- Summary: JDBC test suite fails with recent H2 driver Key: ISPN-1997 URL: https://issues.jboss.org/browse/ISPN-1997 Project: Infinispan Issue Type: Bug Components: Test Suite Affects Versions: 5.1.4.CR1 Reporter: Tristan Tarrant Assignee: Tristan Tarrant Priority: Minor Fix For: 5.1.4.FINAL The binary JDBC cache store expects the ID column to be of type INT but the unit tests create an ID column of type VARCHAR(255). Recent versions of H2 (1.3.x) fail to interpret this correctly. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (ISPN-1394) Investigate possibility of doing manual rehashing

by Galder Zamarreño (JIRA)

Investigate possibility of doing manual rehashing ------------------------------------------------- Key: ISPN-1394 URL: https://issues.jboss.org/browse/ISPN-1394 Project: Infinispan Issue Type: Feature Request Components: Distributed Cache Reporter: Galder Zamarreño Assignee: Manik Surtani Fix For: 5.2.0.FINAL Investigate the possibility of being able to do manual rehashing: - Approach used Dynamo (and Cassandra) - If you're adding 100 nodes, using manual rehashing could reduce traffic and make it more predictable - Could be called via JMX - But removing 10 nodes could be problematic. Unless number of owners is 11 or higher, which will guarantee that at least a copy of data is around -- This message is automatically generated by JIRA.
