09/10/2022, 9:33 AMwhen cold storage is enabled with TTL, telemetry data would be stored at clickhouse default volume disk and AWS S3.
Let's say, default disk for 7 days and 30 days in S3.
When data is queried from SigNoz UI for last 15 days, it automatically aggregates 7 days data from default disk and rest 8 days data from S3.
Data older than 7 days are "eventually" moved to S3 while data older than 30 days are "eventually" removed from S3.
So, there would be no need to view raw data which is being kept at S3.

09/10/2022, 9:36 AMIt is taken care by SigNoz..
You would just have to set TTL value accordingly.
