wal_retrieve_retry_interval

doc html

<p>
        Specifies how long the standby server should wait when WAL data is not
        available from any sources (streaming replication,
        local <code class="filename">pg_wal</code> or WAL archive) before trying
        again to retrieve WAL data.
        If this value is specified without units, it is taken as milliseconds.
        The default value is 5 seconds.
        This parameter can only be set in
        the <code class="filename">postgresql.conf</code> file or on the server
        command line.
       </p><p>
        This parameter is useful in configurations where a node in recovery
        needs to control the amount of time to wait for new WAL data to be
        available. For example, in archive recovery, it is possible to
        make the recovery more responsive in the detection of a new WAL
        file by reducing the value of this parameter. On a system with
        low WAL activity, increasing it reduces the amount of requests necessary
        to access WAL archives, something useful for example in cloud
        environments where the number of times an infrastructure is accessed
        is taken into account.
       </p><p>
        In logical replication, this parameter also limits how often a failing
        replication apply worker or table synchronization worker will be
        respawned.
