Hi guys. Sometime I'm not sure what I have to look at to do queries to build new visualization so I want to check in the db the data available.

SHOW TABLES FROM signoz_metrics;

Gives me a lot of differents tables. Some with the suffix v2 or v4. Is the v4 version the newest used version of the table and v2 just being kept for legacy stuff ? Do you have some documentation that goes deeper into how you organize data into the DB ?
