             Summary: Catalog compaction. Implement remote node part of 
compaction flow
                 Key: IGNITE-22637
                 URL: https://issues.apache.org/jira/browse/IGNITE-22637
             Project: Ignite
          Issue Type: Improvement
            Reporter: Maksim Zhuravkov


To select a compaction time, each node should provide its MinimalRequiredTime 
to compaction coordinator. To compute that time:

1. Get current value of low watermark.
2. Get min check pointed time across all partitions.
3. Get min begin time across all started transaction.
4. Take min of 1., 2., 3.

When the compaction coordinator chooses min catalog version/catalog time, it 
sends a catalog compaction command with this information to each node. Each 
node should execute such command to perform compaction.
