Expand description

Information about WAL checkpointing call for logging.

Fields§

§total_duration: Duration

Duration of the whole WAL checkpointing.

§writers_blocked_duration: Duration

Duration for which WAL checkpointing blocked the writers.

§readers_blocked_duration: Duration

Duration for which WAL checkpointing blocked the readers.

§pages_total: i64

Number of pages in WAL before truncating.

§pages_checkpointed: i64

Number of checkpointed WAL pages.

It should be the same as pages_total unless there are external connections to the database that are not in the pool.
