@brief maximum number of historic logfiles
|
|
`--wal.historic-logfiles`
|
|
|
|
The maximum number of historic logfiles that ArangoDB will keep after they
|
|
have been garbage-collected. If no replication is used, there is no need
|
|
to keep historic logfiles except for having a local changelog.
|
|
|
|
In a replication setup, the number of historic logfiles affects the amount
|
|
of data a slave can fetch from the master's logs. The more historic
|
|
logfiles, the more historic data is available for a slave, which is useful
|
|
if the connection between master and slave is unstable or slow. Not having
|
|
enough historic logfiles available might lead to logfile data being
|
|
deleted
|
|
on the master already before a slave has fetched it.
