Apache Pinot

Hi Team,

We are onboarding on Pinot.
Faced a strange issue that *two tables out of 4 in Pinot got deleted for an unknown reason*. We might have done something wrong.
Any idea about the possible reason for tables deletion. Also any logs I can refer to check this deletion operation. Any help would be appreciated. Thanks

when table is being deleted, the deep store segment files will be put in retention for 7 days (default cluster setting)
usually they are moved from your PinotFS base/&lt;table_name&gt;/&lt;segment_name&gt; to /base/deleted_segments/&lt;table_name&gt;/&lt;segment_name&gt;

you could probably look at the deep store deleted segment and try to find out when that deletion operation occurs, then backtrack into the controller log at that time.

Thanks Rong for the insights. Any reason of default table deletion? is there any configuration that we can do to stop the default table deletion?

there's no default table deletion. it can only happen if someone specifically deleted the table via controller API.
