Later the file is transferred by the parent -# process to the replicas incrementally. -# 2) Diskless: The Redis master creates a new process that directly writes the -# RDB file to replica sockets, without touching the disk at all. -# -# With disk-backed replication, while the RDB file is generated, more replicas -# can be queued and served with the RDB file as soon as the current child -# producing the RDB file finishes its work. With diskless replication instead -# once the transfer starts, new replicas arriving will be queued and a new -# transfer will start when the current one terminates. -# -# When diskless replication is used, the master waits a configurable amount of -# time (in seconds) before starting the transfer in the hope that multiple -# replicas will arrive and the transfer can be parallelized. -# -# With slow disks and fast (large bandwidth) networks, diskless replication -# works better. -repl-diskless-sync yes - -# When diskless replication is enabled, it is possible to configure the delay -# the server waits in order to spawn the child that transfers the RDB via socket -# to the replicas. -# -# This is important since once the transfer starts, it is not possible to serve -# new replicas arriving, that will be queued for the next RDB transfer, so the -# server waits a delay in order to let more replicas arrive. -# -# The delay is specified in seconds, and by default is 5 seconds.

Replicas in this mode can keep serving current -# dataset while replication is in progress, except for cases where -# they can't recognize master as having a data set from same -# replication history. -# Note that this requires sufficient memory, if you don't have it, -# you risk an OOM kill. -# "on-empty-db" - Use diskless load only when current dataset is empty.
