-################################# REPLICATION #################################
|
|
|
-
|
|
|
-# Master-Slave replication. Use slaveof to make a Redis instance a copy of
|
|
|
-# another Redis server. A few things to understand ASAP about Redis replication.
|
|
|
-#
|
|
|
-# 1) Redis replication is asynchronous, but you can configure a master to
|
|
|
-# stop accepting writes if it appears to be not connected with at least
|
|
|
-# a given number of slaves.
|
|
|
-# 2) Redis slaves are able to perform a partial resynchronization with the
|
|
|
-# master if the replication link is lost for a relatively small amount of
|
|
|
-# time. You may want to configure the replication backlog size (see the next
|
|
|
-# sections of this file) with a sensible value depending on your needs.
|
|
|
-# 3) Replication is automatic and does not need user intervention. After a
|
|
|
-# network partition slaves automatically try to reconnect to masters
|
|
|
-# and resynchronize with them.
|
|
|
-#
|
|
|
-# slaveof <masterip> <masterport>
|
|
|
-
|
|
|
-# If the master is password protected (using the "requirepass" configuration
|
|
|
-# directive below) it is possible to tell the slave to authenticate before
|
|
|
-# starting the replication synchronization process, otherwise the master will
|
|
|
-# refuse the slave request.
|
|
|
-#
|
|
|
-# masterauth <master-password>
|
|
|
-
|
|
|
-# When a slave loses its connection with the master, or when the replication
|
|
|
-# is still in progress, the slave can act in two different ways:
|
|
|
-#
|
|
|
-# 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will
|
|
|
-# still reply to client requests, possibly with out of date data, or the
|
|
|
-# data set may just be empty if this is the first synchronization.
|
|
|
-#
|
|
|
-# 2) if slave-serve-stale-data is set to 'no' the slave will reply with
|
|
|
-# an error "SYNC with master in progress" to all the kind of commands
|
|
|
-# but to INFO and SLAVEOF.
|
|
|
-#
|
|
|
-slave-serve-stale-data yes
|
|
|
-
|
|
|
-# You can configure a slave instance to accept writes or not. Writing against
|
|
|
-# a slave instance may be useful to store some ephemeral data (because data
|
|
|
-# written on a slave will be easily deleted after resync with the master) but
|
|
|
-# may also cause problems if clients are writing to it because of a
|
|
|
-# misconfiguration.
|
|
|
-#
|
|
|
-# Since Redis 2.6 by default slaves are read-only.
|
|
|
-#
|
|
|
-# Note: read only slaves are not designed to be exposed to untrusted clients
|
|
|
-# on the internet. It's just a protection layer against misuse of the instance.
|
|
|
-# Still a read only slave exports by default all the administrative commands
|
|
|
-# such as CONFIG, DEBUG, and so forth. To a limited extent you can improve
|
|
|
-# security of read only slaves using 'rename-command' to shadow all the
|
|
|
-# administrative / dangerous commands.

|
|
|
-#
|
|
|
-# New slaves and reconnecting slaves that are not able to continue the replication
|
|
|
-# process just receiving differences, need to do what is called a "full
|
|
|
-# synchronization". An RDB file is transmitted from the master to the slaves.
|
|
|
-# The transmission can happen in two different ways:
|
|
|
-#
|
|
|
-# 1) Disk-backed: The Redis master creates a new process that writes the RDB
|
|
|
-# file on disk. Later the file is transferred by the parent
|
|
|
-# process to the slaves incrementally.
|
|
|
-# 2) Diskless: The Redis master creates a new process that directly writes the
|
|
|
-# RDB file to slave sockets, without touching the disk at all.
|
|
|
-#
|
|
|
-# With disk-backed replication, while the RDB file is generated, more slaves
|
|
|
-# 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 slaves 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 slaves
|
|
|
-# will arrive and the transfer can be parallelized.
|

|
-# There is no simple way for a slave to actually have a exact measure of
|
|
|
-# its "data age", so the following two checks are performed:
|
|
|
-#
|
|
|
-# 1) If there are multiple slaves able to failover, they exchange messages
|
|
|
-# in order to try to give an advantage to the slave with the best
|
|
|
-# replication offset (more data from the master processed).
|
|
|
-# Slaves will try to get their rank by offset, and apply to the start
|
|
|
-# of the failover a delay proportional to their rank.
|
|
|
-#
|
|
|
-# 2) Every single slave computes the time of the last interaction with
|
|
|
-# its master. This can be the last ping or command received (if the master
|
|
|
-# is still in the "connected" state), or the time that elapsed since the
|
|
|
-# disconnection with the master (if the replication link is currently down).
|
|
|
-# If the last interaction is too old, the slave will not try to failover
|
|
|
-# at all.
|
|
|
-#
|
|
|
-# The point "2" can be tuned by user. Specifically a slave will not perform
|
|
|
-# the failover if, since the last interaction with the master, the time
|
|
|
-# elapsed is greater than:
|
|
|
-#
|
|
|
-# (node-timeout * slave-validity-factor) + repl-ping-slave-period

|
|
|
-# slave will not try to failover if it was not able to talk with the master
|
|
|
-# for longer than 310 seconds.
|
|
|
-#
|
|
|
-# A large slave-validity-factor may allow slaves with too old data to failover

-# a master, while a too small value may prevent the cluster from being able to
|
|
|
-# elect a slave at all.

-# at runtime in order to collect data related to possible sources of
|
|
|
-# latency of a Redis instance.
|
|
|
-#
|
|

-# The system only logs operations that were performed in a time equal or

-############################# EVENT NOTIFICATION ##############################
|
|
|
-
|
|
|
-# Redis can notify Pub/Sub clients about events happening in the key space.
|
|
|
-# This feature is documented at http://redis.io/topics/notifications
|
|
|
-#
|
|
|
-# For instance if keyspace events notification is enabled, and a client
|
|
|
-# performs a DEL operation on key "foo" stored in the Database 0, two
|
|
|
-# messages will be published via Pub/Sub:
|
|
|
-#
|
|
|
-# PUBLISH __keyspace@0__:foo del
|
|
|
-# PUBLISH __keyevent@0__:del foo
|
|
|
-#
|
|
|
-# It is possible to select the events that Redis will notify among a set
|
|
|
-# of classes. Every class is identified by a single character:
|
|
|
-#
|
|
|
-# K Keyspace events, published with __keyspace@<db>__ prefix.
|
|
|
-# E Keyevent events, published with __keyevent@<db>__ prefix.
|
|
|
-# g Generic commands (non-type specific) like DEL, EXPIRE, RENAME, ...
|
|
|
-# $ String commands
|
|
|
-# l List commands
|
|
|
-# s Set commands
|
|
|
-# h Hash commands
|
|
|
-# z Sorted set commands
|
|
|
-# x Expired events (events generated every time a key expires)
|
|
|
-# e Evicted events (events generated when a key is evicted for maxmemory)
|
|
|
-# A Alias for g$lshzxe, so that the "AKE" string means all the events.
|
|
|
-#
|
|
|
-# The "notify-keyspace-events" takes as argument a string that is composed
|
|
|
-# of zero or multiple characters. The empty string means that notifications
|
|
|
-# are disabled.
|
|
|
-#
|
|
|
-# Example: to enable list and generic events, from the point of view of the
|
|
|
-# event name, use:
|
|
|
-#
|
|
|
-# notify-keyspace-events Elg
|
|
|
-#
|
|
|
-# Example 2: to get the stream of the expired keys subscribing to channel
|
|
|
-# name __keyevent@0__:expired use:
|
|
|
-#
|
|
|
-# notify-keyspace-events Ex
|
|
|
-#
|
|
|
-# By default all notifications are disabled because most users don't need
|
|

-# this feature and the feature has some overhead. Note that if you don't
|
|
|
-# specify at least one of K or E, no events will be delivered.

-# The client output buffer limits can be used to force disconnection of clients

|
|

-# normal -> normal clients including MONITOR clients
|
|
|
-# slave -> slave clients
|
|
|
-# pubsub -> clients subscribed to at least one pubsub channel or pattern

-# client-output-buffer-limit <class> <hard limit> <soft limit> <soft seconds>

|
-# So for instance if the hard limit is 32 megabytes and the soft limit is

|
|
-# asynchronous clients may create a scenario where data is requested faster
|
|
|
-# than it can read.
