Hi Robert, thanks for your fast reply. Luckily this was a upgrade in QA environment ;) We are running SizeTierCompaction. I wonder whether all those files were created during running sstables command. Unfortunately we didn’t check at that time.
I will try to reproduce again and if this is the case open an issue. However thanks for the link. This is really useful. Thanks!
