Subject [jira] [Created] (IGNITE-12099) Don't write metadata to disk in discovery thread
Date Fri, 23 Aug 2019 13:09:00 GMT
Denis Mekhanikov created IGNITE-12099:

             Summary: Don't write metadata to disk in discovery thread
                 Key: IGNITE-12099
                 URL: https://issues.apache.org/jira/browse/IGNITE-12099
             Project: Ignite
          Issue Type: Improvement
          Components: binary
            Reporter: Denis Mekhanikov

When persistence is enabled, binary metadata is written to disk upon registration. Currently
it happens in the discovery thread, which makes processing of related messages very slow.

A different thread should be used to write metadata to disk. Binary type registration will
be considered finished before information about it will is written to disks on all nodes.

The implementation should guarantee consistency in cases of cluster restarts.
