----------------------------------------
Summary: Metastorage Compaction
Key: IGNITE-20166
URL: https://issues.apache.org/jira/browse/IGNITE-20166
Project: Ignite
Issue Type: Epic
Reporter: Sergey Chugunov
General logic of metastorage is that it supports multiple versions for the same
key corresponding to different timestamps.
At the same time there is a concept of a low watermark - a moment in time when
all timestamps falling below that mark become obsolete and can be pruned from
Metastorage.
We need to implement a mechanism to compact Metastorage to remove obsolete
keys. At the same time some components may rely on availability of history of
key's versions.
