> Disable catalog compaction
> --------------------------

> Key: IGNITE-21585
> URL: https://issues.apache.org/jira/browse/IGNITE-21585
> Project: Ignite
> Issue Type: Improvement
> Reporter: Andrey Mashenkov
> Assignee: Andrey Mashenkov
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-beta2
>
>
> Catalog compaction is not synchronized with transactions on nodes.
> There are a bunch of issues:
> * We expect Catalog compaction should be called for minimal LWM on all the
> nodes. But LWM is node-local value.
> * Recovery RW transaction may require old catalog version to get list of
> indexes, that should be updated.
> * incoming snapshot may require outdated version of catalog in some cases.
> * LWM wait for RO transaction, but not RW.
> So,
> 1. Let's just do nothing with catalog history on compaction.
> 2. Let's node update some key in the metastorage and put it's id. Make node
> will react on it's own updates only. On the key update event, node should
> trigger destroy event for table/index, which are under the LWM.
> We can't trigger local events instead, because we need a causality token for
> VV in several components.
> 2. Fix recovery procedure if needed.
