---------------------------------------

             Summary: Optimize memory usage of data regions in tests
                 Key: IGNITE-9157
                 URL: https://issues.apache.org/jira/browse/IGNITE-9157
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 2.6
            Reporter: Pavel Kovalenko
            Assignee: Pavel Kovalenko
             Fix For: 2.7


If we use persistence in tests and do not explicitly set the max size of a data region, by default it will be 20% of available RAM on a host. This can lead to memory over-usage and sometimes JVMs, where such tests are running, will be killed by Linux OOM killer.
We should find all tests where data region max size has forgotten and set this value explicitly to minimal possible value.
