+# Once the limit is reached Redis will close all the new connections sending

+#
+maxclients %%redisMaxClients
+
+# Don't use more memory than the specified amount of bytes.
+# When the memory limit is reached Redis will try to remove keys
+# according to the eviction policy selected (see maxmemory-policy).
+#
+# If Redis can't remove keys according to the policy, or if the policy is
+# set to 'noeviction', Redis will start to reply with errors to commands
+# that would use more memory, like SET, LPUSH, and so on, and will continue
+# to reply to read-only commands like GET.
+#
+# This option is usually useful when using Redis as an LRU cache, or to set
+# a hard memory limit for an instance (using the 'noeviction' policy).
+#
+# WARNING: If you have slaves attached to an instance with maxmemory on,
+# the size of the output buffers needed to feed the slaves are subtracted
+# from the used memory count, so that network problems / resyncs will
+# not trigger a loop where keys are evicted, and in turn the output
+# buffer of slaves is full with DELs of keys evicted triggering the deletion
+# of more keys, and so forth until the database is completely emptied.
+#
+# In short... if you have slaves attached it is suggested that you set a lower
+# limit for maxmemory so that there is some free RAM on the system for slave
+# output buffers (but this is not needed if the policy is 'noeviction').
+#
+maxmemory %%{redisMaxMemory}mb
+
+# MAXMEMORY POLICY: how Redis will select what to remove when maxmemory
+# is reached. You can select among five behaviors:
+#
+# volatile-lru -> remove the key with an expire set using an LRU algorithm
+# allkeys-lru -> remove any key according to the LRU algorithm
+# volatile-random -> remove a random key with an expire set
+# allkeys-random -> remove a random key, any key
+# volatile-ttl -> remove the key with the nearest expire time (minor TTL)
+# noeviction -> don't expire at all, just return an error on write operations
+#
+# Note: with any of the above policies, Redis will return an error on write
+#       operations, when there are no suitable keys for eviction.
+#
+#       At the date of writing these commands are: set setnx setex append
+#       incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd
+#       sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby
+#       zunionstore zinterstore hset hsetnx hmset hincrby incrby decrby

+#
+# The default is:
+#
+maxmemory-policy %%redisMemoryPolicySlave
+
+# LRU and minimal TTL algorithms are not precise algorithms but approximated
+# algorithms (in order to save memory), so you can tune it for speed or
+# accuracy. For default Redis will check five keys and pick the one that was
+# used less recently, you can change the sample size using the following
+# configuration directive.
+#
+# The default of 5 produces good enough results. 10 Approximates very closely

+#
+# no: don't fsync, just let the OS flush the data when it wants. Faster.
+# always: fsync after every write to the append only log. Slow, Safest.
+# everysec: fsync only one time every second. Compromise.
+#
+# The default is "everysec", as that's usually the right compromise between
+# speed and data safety. It's up to you to understand if you can relax this to
+# "no" that will let the operating system flush the output buffer when
+# it wants, for better performances (but if you can live with the idea of
+# some data loss consider the default persistence mode that's snapshotting),
+# or on the contrary, use "always" that's very slow but a bit safer than

+# When the AOF fsync policy is set to always or everysec, and a background

+# Redis may block too long on the fsync() call. Note that there is no fix for
+# this currently, as even performing fsync in a different thread will block
+# our synchronous write(2) call.
+#
+# In order to mitigate this problem it's possible to use the following option
+# that will prevent fsync() from being called in the main process while a
+# BGSAVE or BGREWRITEAOF is in progress.
+#
+# This means that while another child is saving, the durability of Redis is
+# the same as "appendfsync none". In practical terms, this means that it is
+# possible to lose up to 30 seconds of log in the worst scenario (with the

+#
+# This is how it works: Redis remembers the size of the AOF file after the
+# latest rewrite (if no rewrite has happened since the restart, the size of
+# the AOF at startup is used).
+#
+# This base size is compared to the current size. If the current size is
+# bigger than the specified percentage, the rewrite is triggered. Also
+# you need to specify a minimal size for the AOF file to be rewritten, this
+# is useful to avoid rewriting the AOF file even if the percentage increase

+# data=ordered option (however this can't happen when Redis itself
+# crashes or aborts but the operating system still works correctly).
+#
+# Redis can either exit with an error when this happens, or load as much

+# Note that if the AOF file will be found to be corrupted in the middle

+# ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+# WARNING EXPERIMENTAL: Redis Cluster is considered to be stable code, however
+# in order to mark it as "mature" we need to wait for a non trivial percentage
+# of users to deploy it in production.
+# ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+#
+# Normal Redis instances can't be part of a Redis Cluster; only nodes that are
+# started as cluster nodes can. In order to start a Redis instance as a
+# cluster node enable the cluster support uncommenting the following:
+#
+cluster-enabled yes
+
+# Every cluster node has a cluster configuration file. This file is not
+# intended to be edited by hand. It is created and updated by Redis nodes.
+# Every Redis Cluster node requires a different cluster configuration file.
+# Make sure that instances running in the same system do not have
+# overlapping cluster configuration file names.
+#
+cluster-config-file nodes-slave.conf
+
+# Cluster node timeout is the amount of milliseconds a node must be unreachable
+# for it to be considered in failure state.
+# Most other internal time limits are multiple of the node timeout.
+#
+cluster-node-timeout 15000
+
+# A slave of a failing master will avoid to start a failover if its data
+# looks too old.
+#
+# 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
+#
+# So for example if node-timeout is 30 seconds, and the slave-validity-factor
+# is 10, and assuming a default repl-ping-slave-period of 10 seconds, the
+# 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.
+#
+# For maximum availability, it is possible to set the slave-validity-factor
+# to a value of 0, which means, that slaves will always try to failover the
+# master regardless of the last time they interacted with the master.
+# (However they'll always try to apply a delay proportional to their
+# offset rank).
+#
+# Zero is the only value able to guarantee that when all the partitions heal
+# the cluster will always be able to continue.
+#
+cluster-slave-validity-factor 10
+
+# Cluster slaves are able to migrate to orphaned masters, that are masters
+# that are left without working slaves. This improves the cluster ability
+# to resist to failures as otherwise an orphaned master can't be failed over
+# in case of failure if it has no working slaves.
+#
+# Slaves migrate to orphaned masters only if there are still at least a
+# given number of other working slaves for their old master. This number
+# is the "migration barrier". A migration barrier of 1 means that a slave
+# will migrate only if there is at least 1 other working slave for its master
+# and so forth. It usually reflects the number of slaves you want for every
+# master in your cluster.
+#
+# Default is 1 (slaves migrate only if their masters remain with at least
+# one slave). To disable migration just set it to a very large value.
+# A value of 0 can be set but is useful only for debugging and dangerous
+# in production.
+#
+cluster-migration-barrier 1
+
+# By default Redis Cluster nodes stop accepting queries if they detect there
+# is at least an hash slot uncovered (no available node is serving it).
+# This way if the cluster is partially down (for example a range of hash slots
+# are no longer covered) all the cluster becomes, eventually, unavailable.
+# It automatically returns available as soon as all the slots are covered again.
+#
+# However sometimes you want the subset of the cluster which is working,
+# to continue to accept queries for the part of the key space that is still
+# covered. In order to do so, just set the cluster-require-full-coverage
+# option to no.

+################################## SLOW LOG ###################################
+
+# The Redis Slow Log is a system to log queries that exceeded a specified
+# execution time. The execution time does not include the I/O operations
+# like talking with the client, sending the reply and so forth,
+# but just the time needed to actually execute the command (this is the only
+# stage of command execution where the thread is blocked and can not serve
+# other requests in the meantime).
+#
+# You can configure the slow log with two parameters: one tells Redis
+# what is the execution time, in microseconds, to exceed in order for the
+# command to get logged, and the other parameter is the length of the
+# slow log. When a new command is logged the oldest one is removed from the
+# queue of logged commands.
+
+# The following time is expressed in microseconds, so 1000000 is equivalent
+# to one second. Note that a negative number disables the slow log, while
+# a value of zero forces the logging of every command.

+################################ LATENCY MONITOR ##############################

+#
+# By default latency monitoring is disabled since it is mostly not needed
+# if you don't have latency issues, and collecting data has a performance

+############################# 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.
