[jira] [Created] (IGNITE-5411) Persist affinity key on disc

Vladimir Ozerov created IGNITE-5411:
---------------------------------------

             Summary: Persist affinity key on disc
                 Key: IGNITE-5411
                 URL: https://issues.apache.org/jira/browse/IGNITE-5411
             Project: Ignite
          Issue Type: Task
          Components: binary
            Reporter: Vladimir Ozerov
             Fix For: 2.1


Currently binary metadata is not persisted on a disk anyhow. It means that after full cluster restart we will loose all runtime metadata (except of those configured explicitly in {{IgniteConfiguration.binaryConfiguration}}.

In future releases we will store metadata in separate storage. For now I propose only to store typeId -> affinityKey mapping on disc to improve value of {{CREATE TABLE}} feature where affinity key is essential for data co-location.
