Vitaliy Biryukov updated IGNITE-7986:
-------------------------------------
Description:
GridPartitionStateMap based on BitSet. And the size of a BitSet depends on the
maximum key element, and not on the number of elements.
Just using the "BitSet.nextSetBit" method, will improve the performance of the
iterator for big clusters or caches with a large number of partitions.
was:
GridPartitionStateMap based on BitSet. And the size of a BitSet depends on the
maximum key element, and not on the number of elements.
As far as I understand, size of the GridPartitionStateMap depends on the
number of nodes in the cluster, the number of backups and the number of
partitions (except local map).
