Hi.. I have a clarification question. On this page: https://signoz.io/docs/userguide/retention-period/ it says both:

When retention settings are updated, the changes apply only to newly ingested data. Existing data retains the previous retention settings, as updating retention for existing data is a resource-intensive process.

and

SigNoz UI is loading slower than usual after updating retention period.
This is because the retention period update is a long running operation when there's lot of data, it might require a lot of resources and can cause performance issues. So, it is recommended to update retention period when there is less traffic on the platform or increase resources for the clickhouse.

which one is it? 🙂

That does seem weird since Clickhouse suggests TTL is a rule and not per-row metadata, i.e. the opposite of both statements should be true on a vanilla table using TTL rules: https://clickhouse.com/docs/guides/developer/ttl

It’s the first one 🙈 Older version use to update the existing data, which we have disabled in the new version. Will get it updated.
