Subject Wrong concistency level
Date Tue, 01 Jan 2019 08:18:11 GMT
Hi All and Happy New Year!!!
This year started with Cassandra 3.11.3 sometimes forces level ALL despite query level LOCAL_QUORUM
(actually there is only one DC) and it fails with timeout.
As far as I understand, it can be caused by read repair attempts (we see "DigestMismatch"
errors in Cassandra log), but table has no read repair configured:
    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.SizeTieredCompactionStrategy',
'max_threshold': '32', 'min_threshold': '4'}
    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 = 0.0
    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 = '99PERCENTILE';


Any suggestions?
Thanks.
