[jira] [Created] (IGNITE-5323) Move record serializer version from
file name to file header
Alexey Goncharuk created IGNITE-5323:
----------------------------------------
Summary: Move record serializer version from file name to file header
Key: IGNITE-5323
URL: https://issues.apache.org/jira/browse/IGNITE-5323
Project: Ignite
Issue Type: Improvement
Components: cache
Affects Versions: 2.1
Reporter: Alexey Goncharuk
Assignee: Konstantin Dudkov
Fix For: 2.1
Keeping records serializer version in the WAL segment file name makes it hard to implement forward serializer version update because we need to rename files on recovery.
Instead, we should write serializer version in the file header and use it when reading records.
We should also add some boilerplate code in order to make it easier to add new serializer versions in the future.
