Yes. For `transcriptss_OFFLINE` table ,I didn't configure a retention
strategy.I guess the old segments of this table were deleted based on segment
lineage, cause there are indeed a few old segments that have been deleted based
on segments' screenshots above.
I guess the reason that I didn't see these old segments name from [this
log](https://github.com/apache/pinot/blob/b8fecb9d5a8fe524c42e29ce99ccf5012a2ebd49/pinot-controller/src/main/java/org/apache/pinot/controller/helix/core/retention/RetentionManager.java#L258)
is log manager has deleted the log file.I found the default log configuration
only maintain 10 log gzip files.

Thanks for helping me again,I will just close this issue :)
