[JBoss JIRA] (ISPN-5515) Preload only on the node that starts up the first

by Dan Berindei (JIRA)

[ https://issues.jboss.org/browse/ISPN-5515?page=com.atlassian.jira.plugin.... ] Dan Berindei updated ISPN-5515: ------------------------------- Status: Open (was: New) > Preload only on the node that starts up the first > ------------------------------------------------- > > Key: ISPN-5515 > URL: https://issues.jboss.org/browse/ISPN-5515 > Project: Infinispan > Issue Type: Enhancement > Components: Core, Loaders and Stores > Affects Versions: 7.2.2.Final, 8.0.0.Alpha1 > Reporter: Dan Berindei > Assignee: Dan Berindei > Fix For: 8.0.0.Alpha2 > > > Preloading happens before communicating with other nodes that might already have the cache running. When joining the existing members, the cache then waits to receive the first CH in which it is a member, and then deletes only the entries in the segments that it doesn't own in that CH. > The intention of this was to remove as little as possible from the existing data, e.g. if the first node to start up is not the one that was stopped last. But the preloaded entries are not replicated to the other nodes, so this can lead to inconsistencies. > It would be better to delay preloading until we know we are the first node to start up, but failing that we could clear the data container and the store before receiving the initial state. > Note that this will only allow preloading data from one node. Restoring data from more nodes is harder to do, and we will implement it as part of graceful restart. -- This message was sent by Atlassian JIRA (v6.3.15#6346)

[JBoss JIRA] (ISPN-5517) JDBCBinaryStore size method should query count directly instead of iterating

by William Burns (JIRA)

William Burns created ISPN-5517: ----------------------------------- Summary: JDBCBinaryStore size method should query count directly instead of iterating Key: ISPN-5517 URL: https://issues.jboss.org/browse/ISPN-5517 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Reporter: William Burns Fix For: 8.0.0.Final JDBCBinaryStore size method iterates upon all of the rows in the database. We should instead use the getCountRowsSql from the table manipulation just like JDBCStringBasedStore. -- This message was sent by Atlassian JIRA (v6.3.15#6346)

[JBoss JIRA] (ISPN-5516) SingleFileStore should skip loading from disk if value and metadata are not requested

by William Burns (JIRA)

William Burns created ISPN-5516: ----------------------------------- Summary: SingleFileStore should skip loading from disk if value and metadata are not requested Key: ISPN-5516 URL: https://issues.jboss.org/browse/ISPN-5516 Project: Infinispan Issue Type: Enhancement Components: Loaders and Stores Affects Versions: 8.0.0.Alpha1 Reporter: William Burns Fix For: 8.0.0.Final SingleFileStore internally stores all of the keys in memory. If the loader task doesn't require values or metadata there is no reason to go to disk as all of the information is already present in its key cache. -- This message was sent by Atlassian JIRA (v6.3.15#6346)

[JBoss JIRA] (ISPN-5033) Lack of EmbeddedCacheManager.undefineConfiguration(String) can cause memory/classloader leaks

Obviously, this wouldn't work with asynchronous prepare/commit/rollback. -- This message was sent by Atlassian JIRA (v6.3.15#6346)

[JBoss JIRA] (ISPN-5515) Preload only on the node that starts up the first

by Sanne Grinovero (JIRA)

[ https://issues.jboss.org/browse/ISPN-5515?page=com.atlassian.jira.plugin.... ] Sanne Grinovero commented on ISPN-5515: --------------------------------------- What guarantees do you have for this data to be valid? The definition of "first" seems rather subjective to me, and you have no idea how long ago that data was stored. Maybe this node has been down for the last month, while all other nodes worked and now this is being restarted. > Preload only on the node that starts up the first > ------------------------------------------------- > > Key: ISPN-5515 > URL: https://issues.jboss.org/browse/ISPN-5515 > Project: Infinispan > Issue Type: Enhancement > Components: Core, Loaders and Stores > Affects Versions: 7.2.2.Final, 8.0.0.Alpha1 > Reporter: Dan Berindei > Assignee: Dan Berindei > Fix For: 8.0.0.Alpha2 > > > Preloading happens before communicating with other nodes that might already have the cache running.
