//////////////////////////////////////////////////////////////////////////////// /// @startDocuBlock WalLogfileHistoricLogfiles /// @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. /// @endDocuBlock ////////////////////////////////////////////////////////////////////////////////
