DS210 DSE6 Operations Course: Time Window Compaction: https://academy.datastax.com/units/21017-time-window-compaction-dse-operations-apache-cassandra
At 4:00 minute of the video. The slide mentions:
expired_sstable_check_frequency_seconds determines how often to check for fully expired (tombstoned) SSTables.
Can you please give the link to the documentation related to that
expired_sstable_check_frequency_seconds parameter? Surprisingly there is verly little mention of that param on the internet. A search on DataStax documentation https://docs.datastax.com/en/dse/6.8/dse-admin/search.html?searchQuery=exprired_sstable_check_frequency_seconds ended up with zero hit.
In case this param had become obsolete in modern Cassandra. Maybe this video should be updated?
