[GitHub] [pinot] lksvenoy-r7 opened a new issue, #8811: Delete all segments API does not respect retention period
lksvenoy-r7 opened a new issue, #8811:
URL: https://github.com/apache/pinot/issues/8811
I just tried to use the API for deleting segments `/segments/{tableName} ` through the swagger documentation, and found that it did not respect the retention policy I specified.

After executing the following command, all the segments in the table disappeared.

Hi @lksvenoy-r7, this is expected behavior from the delete api. It is indeed expected to delete all (or specified) segments for a table. Retention is auto-managed (via periodic job) and does not require explicit trigger to delete segments.
But, I am curious to learn what's the user experience you are looking for in this case.

This retention is not the retention for the table, but the retention for the deleted segments. When you specify `3d` here, Pinot will keep the deleted segments under the `deletedSegments` folder for 3 days before deleting them completely. We use this retention in case user accidentally deletes the segments and want to recover.

Thanks for the responses @Jackie-Jiang @mayankshriv. That makes sense now, just a slightly confusing API. I'll close this issue as it was simply a misunderstanding
