Yes, your are right. I am using STCS compaction strategy with some kind of
timeseries model. Too much disk space has been occupied.
What should I do to stop the disk full ?
I only want to keep 100 days data most recently, so I set
default_time_to_live = 8640000(100 days ).
I know I need to do something to stop the disk space cost, but I really don’t
know how to do it.
Here is the strategy of the big data table :
AND compaction = {'class':
'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy',
'max_threshold': '32', 'min_threshold': '12', 'tombstone_threshold': '0.1',
'unchecked_tombstone_compaction': 'true'}
AND compression = {'chunk_length_in_kb': '64', 'class':
'org.apache.cassandra.io.compress.LZ4Compressor'}
AND crc_check_chance = 1.0
AND dclocal_read_repair_chance = 0.1
AND default_time_to_live = 8640000
AND gc_grace_seconds = 432000
