             Summary: Cassandra stops compacting
                 Key: CASSANDRA-12614
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12614
             Project: Cassandra
          Issue Type: Bug
          Components: Compaction
         Environment: linux cas-2.1.15
            Reporter: Pavel Trukhanov


After some issues 3 out of 9 our cassandra nodes stopped to compact one particular cf. So we see constantly increasing number of sstables for that cf.
While other cfs on these nodes and other nodes keep compacting.

This cf has DTCS.
Here's desc:

CREATE TABLE okmeter.bunches (
    bunch_key text,
    bunch_ts bigint,
    version uuid,
    value blob,
    PRIMARY KEY (bunch_key, bunch_ts, version)
) WITH COMPACT STORAGE
    AND CLUSTERING ORDER BY (bunch_ts DESC, version ASC)
    AND bloom_filter_fp_chance = 0.01
    AND caching = '\{"keys":"ALL", "rows_per_partition":"NONE"\}'
    AND comment = ''
    AND compaction = \{'class': 'org.apache.cassandra.db.compaction.DateTieredCompactionStrategy', 'max_window_size_seconds': '3686400', 'base_time_seconds': '14400', 'max_sstable_age_days': '90'\}
    AND compression = {}
    AND dclocal_read_repair_chance = 0.1
    AND default_time_to_live = 0
    AND gc_grace_seconds = 864000
    AND max_index_interval = 2048
    AND memtable_flush_period_in_ms = 0
    AND min_index_interval = 128
    AND read_repair_chance = 0.0
    AND speculative_retry = '99.0PERCENTILE';
{quote}

I couldn't find anything interesting in logs.

I've tried drain & restart - no luck.

I've tried to disable/enable autocompation - nothing's changed.

I've tried force major - it works but sstable count starts increasing after major is done. 

It seems that it just completely ignores autocompaction enabled.
