----------------------------------------
Summary: Add EvitionPolicy factory support in IgniteConfiguration.
Key: IGNITE-6649
URL: https://issues.apache.org/jira/browse/IGNITE-6649
Project: Ignite
Issue Type: Bug
Security Level: Public (Viewable by anyone)
Components: cache
Reporter: Andrew Mashenkov
Fix For: 2.4
For now the only way to set EvictionPolicy to IgniteConfiguration is to use
EvictionPolicy instance.
That looks error prone as user can easily share instance between caches or
cache reincarnations and got unexpected results.
E.g. it can cause an AssertionError if EvictionPolicy is reused.
Steps to reproduce.
1. Create CacheConfiguration object that will be reused.
2. Create and fill a cache.
3. Destroy cache and create cache again with same CacheConfiguration object.
4. One of next put can fails with stacktrace below.
The error is throws when EvictionPolicy tries to evict entries from cache that
has just been destroyed.
java.lang.AssertionError
