------------------------------------------
Summary: Advanced heuristics for historical rebalance
Key: IGNITE-13253
URL: https://issues.apache.org/jira/browse/IGNITE-13253
Project: Ignite
Issue Type: Improvement
Reporter: Vladislav Pyatkov
Before, cluster detects partitions that have not to rebalance by history, by
them size. This threshold might be set through a system property
IGNITE_PDS_WAL_REBALANCE_THRESHOLD. But it is not fair deciding which
partitions will be rebalanced by WAL only by them size. WAL can have much more
records than size of a partition (many update by one key) and that rebalance
required more data than full transferring by network.
Need to implement a heuristic, that might to estimate data size.
