WAL files.
|For example, suppose
checkpoint_interval
= 2 and
checkpoint_count
= 5
and the average amount that Tarantool writes between each checkpoint interval
= 1 GB.
Then one could calculate that the necessary amount is (251) 10GB.
But this calculation would be wrong if, instead of writing 1 GB
during one checkpoint interval,
Tarantool encounters an unusual spike and tries to write 11 GB,
causing an operating-system ENOSPC (“no space”) error.
By setting checkpoint_wal_threshold to a lower value, say 9 GB,
an administrator could prevent the error.|Type: integer

The example is confusing.
