Our Java Application doing a batch inserts on 1 of the table, That table schema is something like..
CREATE TABLE "My_KeySpace"."my_table" (
key text,
column1 varint,
column2 bigint,
column3 text,
column4 boolean,
value blob,
PRIMARY KEY (key, column1, column2, column3, column4)
) WITH CLUSTERING ORDER BY ( column1 DESC, column2 DESC, column3 ASC, column4 ASC )
AND COMPACT STORAGE
AND bloom_filter_fp_chance = 0.1
AND comment = ''
AND crc_check_chance = 1.0
AND dclocal_read_repair_chance = 0.0
AND default_time_to_live = 0
AND gc_grace_seconds = 0
AND max_index_interval = 2048
AND memtable_flush_period_in_ms = 0
AND min_index_interval = 128
AND read_repair_chance = 0.1
AND speculative_retry = 'NONE'
AND caching = {
'keys' : 'ALL',
'rows_per_partition' : 'NONE'
}
AND compression = {
'chunk_length_in_kb' : 64,
'class' : 'LZ4Compressor',
'enabled' : true
}
AND compaction = {
'class' : 'LeveledCompactionStrategy',
'sstable_size_in_mb' : 5
};
gc_grace_seconds = 0 in above schema. Because of this I am getting following warning:
2019-02-05 01:59:53.087 WARN [SharedPool-Worker-5 - org.apache.cassandra.cql3.statements.BatchStatement:97] Executing a LOGGED BATCH on table [My_KeySpace.my_table], configured with a gc_grace_seconds of 0. The gc_grace_seconds is used to TTL batchlog entries, so setting gc_grace_seconds too low on tables involved in an atomic batch might cause batchlog entries to expire before being replayed.
I have seen Cassandra code, this warning is there for obvious reasons at: this line
Any solution without changing batch code in application?? Should I increase gc_grace_seconds?
