[jira] [Commented] (IGNITE-6977) Wrong initial BitSet size in
GridPartitionStateMap
[ https://issues.apache.org/jira/browse/IGNITE-6977?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16260902#comment-16260902 ]
Alexander Belyak commented on IGNITE-6977:
------------------------------------------
Minor memory consumption even in huge topologies/cacheGroup numbers.
> Wrong initial BitSet size in GridPartitionStateMap
> --------------------------------------------------

> Key: IGNITE-6977
> URL: https://issues.apache.org/jira/browse/IGNITE-6977
> Project: Ignite
> Issue Type: Bug
> Components: general
> Affects Versions: 2.1
> Reporter: Alexander Belyak
> Priority: Minor
>
> In constructor of org.apache.ignite.internal.utilGridPartitionStateMap(int parts) {
> states = new BitSet(parts);
> }
> we initialize BitSet with part bit, but use private static final int BITS for each partition state. As result long[] in BitSet get difficult predictable size (depends of access order it can be exact as needed or almost twice bigger with at least one additional array copying)
