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
|
||||
log 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 amount of times an infrastructure is accessed
|
||||
is taken into account.
