Hello, I have many updates happening in the DB. All of them works with millions of rows. When this happens I get the following message:
checkpoints are occurring too frequently (294 seconds apart) Consider increasing the configuration parameter "checkpoint_segments". Some values from my postgresql.conf files are as follows. My question is do I really increase the checkpoint segments or should I increase the WAL buffers or do an create table as and then insert instead of update statement? shared_buffers = 20000 #60000 # min 16 or max_connections*2, 8KB each -- Bizgres work_mem = 65536 #131072 #65536 # min 64, size in KB -- Bizgres Database change from 1024 to 65536 maintenance_work_mem = 524288 #131072 # min 1024, size in KB max_fsm_pages = 8000000 # min max_fsm_relations*16, 6 bytes each max_fsm_relations = 32768 # min 100, ~70 bytes each fsync = on # turns forced synchronization on or off wal_buffers = 128 # min 4, 8KB each checkpoint_segments = 256 # in logfile segments, min 1, 16MB each checkpoint_timeout = 3600 #300 # range 30-3600, in seconds checkpoint_warning = 300 # in seconds, 0 is off default_statistics_target = 250 # range 1-1000 Thanks Abu --------------------------------- Have a burning question?
