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.
