pgroonga_wal_applier.naptime parameter

Since 2.3.3.


pgroonga_wal_applier.naptime parameter controls WAL application interval by pgroonga_wal_applier module.

The larger value, the larger pgroonga.max_wal_size parameter value is required.

The smaller value, the more needless CPU load.


In postgresql.conf:

pgroonga_wal_applier.naptime = interval

interval's default unit is second. You can change unit by specify suffix such as min for minutes.

The default is 60 seconds.


Here is an example to specify 10 minutes:

pgroonga_wal_applier.naptime = 10min
