[JBoss JIRA] Created: (JBCACHE-1417) Dynamic resizing of shared lock collection for MVCC write locks based on load/cache size

by Manik Surtani (JIRA)

Dynamic resizing of shared lock collection for MVCC write locks based on load/cache size ---------------------------------------------------------------------------------------- Key: JBCACHE-1417 URL: https://jira.jboss.org/jira/browse/JBCACHE-1417 Project: JBoss Cache Issue Type: Feature Request Security Level: Public (Everyone can see) Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 3.0.0.GA A few ideas here: Users could provide a min and max concurrency level, or a factor of number of nodes in the cache. Need to think of an efficient way to resize the lock collection without affecting ongoing operations. Would also need to consider intelligent collection monitoring to make sure hash functions spread nodes across the locks well, otherwise consider altering the hash function. -- 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: (JBCACHE-1464) Ability to do bulk gets with TCPCacheLoader

Ability to do bulk gets with TCPCacheLoader ------------------------------------------- Key: JBCACHE-1464 URL: https://jira.jboss.org/jira/browse/JBCACHE-1464 Project: JBoss Cache Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Cache loaders Reporter: J B Assignee: Manik Surtani Priority: Minor It would be great if one could make a bulk "get" call through the TcpCacheLoader, currently one has to make many call single calls to get data from the TcpCacheServer. It would be nice to be able to query in bulk for a list of Fqns. -- 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] Updated: (JBCACHE-1214) Can the cache be backed by LinkedHashSet instead of HashSet

by Manik Surtani (JIRA)

The primary reason for wanting it to be backed by a LinkedHashSet is the guaranteed ordering of the elements when iterated over. Having this guarantee would facilitate implementations of say a TableModel, but would make other iterations more predictable too. -- 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: (JBCACHE-1421) Optimize writes on primitives and Strings to short-circuit if there are no changes

by Manik Surtani (JIRA)

Optimize writes on primitives and Strings to short-circuit if there are no changes ---------------------------------------------------------------------------------- Key: JBCACHE-1421 URL: https://jira.jboss.org/jira/browse/JBCACHE-1421 Project: JBoss Cache Issue Type: Feature Request Security Level: Public (Everyone can see) Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 3.1.0 E.g., cache.put(fqn, "key", "Hello"); // tx 1 ... wait ... cache.put(fqn, "key", "Hello"); // tx 2 tx 2 should be able to short-circuit the process if there is no change in the payload. Only makes sense for primitives and Strings though. Even primitive arrays are not worth it since it would involve iterating through the array. -- 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
