After some time with 2.X, i saw the Clickhouse container was growing in size very fast despite not having that much stats going on.
After some lookup with it i saw it was that by default the Clickhouse system adds stats without TTL, so it just accumulate over time.
To fix that you can remove the current system stats, and adds a TTL to them so it grows but not too much :
SQL

Summary
ClickHouse database is continuously growing in size when working with Appwrite. It is suggested to review the open pull request on GitHub for potential solutions.
