Most aggregate functions support multi-stage distributed execution in which on every node we perform a local aggregation, then we route all the intermediate results to all of the nodes (according to the grouping columns), and then we perform a final aggregation that gives us the result.

Sometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.

if leader && s.raft.State() != raft.Leader {
return nil, ErrNotLeader
}

s.mu.Lock()

## Python/Regex fix
This is a reminder for me or a task if anyone wants :P
Basically, The last two questions aren't really regex's questions.
To do:
- Move said questions to correct place.
