Test demonstrating issue with rebalancing for PDS and TTL attached
> Store TTL expire times in B+ tree on per-partition basis
> --------------------------------------------------------
>
> Key: IGNITE-5874
> URL: https://issues.apache.org/jira/browse/IGNITE-5874
> Project: Ignite
> Issue Type: Improvement
> Components: cache, persistence
> Affects Versions: 2.1
> Reporter: Ivan Rakov
> Attachments: IgnitePdsWithTtlTest.java
>
>
> TTL expire times for entries are stored in PendingEntriesTree, which is
> singleton for cache. When expiration occurs, all system threads iterate
> through the tree in order to remove expired entries. Iterating through single
> tree causes contention and perfomance loss.
> Related performance issue: https://issues.apache.org/jira/browse/IGNITE-5793
> We should keep instance of PendingEntriesTree for each partition, like we do
> for CacheDataTree.
