Hi All. If We build a pinot cluster without deep storage , The controller will store all the segments in controller disk configured in

controller.data.dir

, If there have some methods to delete controller segments with retention times, since we don’t have enough disk space to store in controller?

In the table config, you can set retentionTimeValue and retentionTimeUnit. Check out the table config documentation

Thx for your replay, But I am confused that, if we keep table retentionTimeValue very long like 1 year , all the segments still need stored in controller, which will make controller node full quickly

Typically, you would attach an NFS to the contollers for this.

right, all segments are kept in segment tar gz format in controller for backup purpose. If you don’t keep that copy in controller, then once you lost a server, you may not have that segment recovered.
