-----------------------------------------
Summary: Make system cache non-persistent and deprecate.
Key: IGNITE-11483
URL: https://issues.apache.org/jira/browse/IGNITE-11483
Project: Ignite
Issue Type: Bug
Components: cache, compute, igfs, managed services
Reporter: Andrew Mashenkov
For now, persistent Default Region makes System cache persistent as well (same
correct for non-persistent region). This behavior is non-obvious and it may
causes unpredictable issues.
We have number of components that uses system cache, some of them doesn't need
system cache to be persistent, while other ok with it:
* DataStructures - datastructures persistence should be configured in it's
configuration. Moreover, some structures looks broken as
CacheDataStructureManages uses in-memory maps.
* Compute - most likely persistence not needed.
* Services - metastore can be used instead.
* Igfs - candidate to remove in 3.0
