+# Redis configuration file example
+
+# Note on units: when memory size is needed, it is possible to specifiy
+# it in the usual form of 1k 5GB 4M and so forth:
+#
+# 1k => 1000 bytes
+# 1kb => 1024 bytes
+# 1m => 1000000 bytes
+# 1mb => 1024*1024 bytes
+# 1g => 1000000000 bytes
+# 1gb => 1024*1024*1024 bytes
+#
+# units are case insensitive so 1GB 1Gb 1gB are all the same.
+
+# By default Redis does not run as a daemon. Use 'yes' if you need it.
+# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.

+# specified all the interfaces will listen for incoming connections.
+#
+# bind 127.0.0.1
+
+# Specify the path for the unix socket that will be used to listen for

+# Set server verbosity to 'debug'
+# it can be one of:
+# debug (a lot of information, useful for development/testing)
+# verbose (many rarely useful info, but not a mess like the debug level)
+# notice (moderately verbose, what you want in production probably)

+# Save the DB on disk:
+#
+# save <seconds> <changes>
+#
+# Will save the DB if both the given number of seconds and the given
+# number of write operations against the DB occurred.
+#
+# In the example below the behaviour will be to save:

+# after 300 sec (5 min) if at least 10 keys changed
+# after 60 sec if at least 10000 keys changed

+
+################################# REPLICATION #################################
+
+# Master-Slave replication. Use slaveof to make a Redis instance a copy of
+# another Redis server. Note that the configuration is local to the slave
+# so for example it is possible to configure the slave to save the DB with a
+# different interval, or to listen to another port, and so on.
+#
+# 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 lost the 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 data 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
+
+# Slaves send PINGs to server in a predefined interval. It's possible to change
+# this interval with the repl_ping_slave_period option. The default value is 10
+# seconds.
+#
+# repl-ping-slave-period 10
+
+# The following option sets a timeout for both Bulk transfer I/O timeout and
+# master data or ping response timeout. The default value is 60 seconds.
+#
+# It is important to make sure that this value is greater than the value
+# specified for repl-ping-slave-period otherwise a timeout will be detected
+# every time there is low traffic between the master and the slave.
+#
+# repl-timeout 60
+
+################################## SECURITY ###################################
+
+# Require clients to issue AUTH <PASSWORD> before processing any other
+# commands. This might be useful in environments in which you do not trust
+# others with access to the host running redis-server.
+#
+# This should stay commented out for backward compatibility and because most
+# people do not need auth (e.g. they run their own servers).
+#
+# Warning: since Redis is pretty fast an outside user can try up to
+# 150k passwords per second against a good box. This means that you should
+# use a very strong password otherwise it will be very easy to break.
+#
+# requirepass foobared
+
+# Command renaming.
+#
+# It is possilbe to change the name of dangerous commands in a shared
+# environment. For instance the CONFIG command may be renamed into something
+# of hard to guess so that it will be still available for internal-use
+# tools but not available for general clients.
+#
+# Example:
+#
+# rename-command CONFIG b840fc02d524045429941cc15f59e41cb7be6c52
+#
+# It is also possilbe to completely kill a command renaming it into
+# an empty string:
+#
+# rename-command CONFIG ""
+
+################################### LIMITS ####################################
+
+# Set the max number of connected clients at the same time. By default there
+# is no limit, and it's up to the number of file descriptors the Redis process
+# is able to open. The special value '0' means no limits.
+# Once the limit is reached Redis will close all the new connections sending
+# an error 'max number of clients reached'.
+#
+# maxclients 128
+
+# Don't use more memory than the specified amount of bytes.
+# When the memory limit is reached Redis will try to remove keys
+# accordingly to the eviction policy selected (see maxmemmory-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
+# an 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 <bytes>
+
+# MAXMEMORY POLICY: how Redis will select what to remove when maxmemory
+# is reached? You can select among five behavior:
+#
+# volatile-lru -> remove the key with an expire set using an LRU algorithm
+# allkeys-lru -> remove any key accordingly 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 all the kind of policies, Redis will return an error on write
+# operations, when there are not suitable keys for eviction.
+#
+# At the date of writing this 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
+# getset mset msetnx exec sort
+#
+# The default is:
+#
+# maxmemory-policy volatile-lru
+
+# LRU and minimal TTL algorithms are not precise algorithms but approximated
+# algorithms (in order to save memory), so you can select as well the sample
+# size to check. For instance for default Redis will check three keys and
+# pick the one that was used less recently, you can change the sample size
+# using the following configuration directive.
+#
+# maxmemory-samples 3
+
+############################## APPEND ONLY MODE ###############################
+
+# By default Redis asynchronously dumps the dataset on disk. If you can live
+# with the idea that the latest records will be lost if something like a crash
+# happens this is the preferred way to run Redis. If instead you care a lot
+# about your data and don't want to that a single record can get lost you should
+# enable the append only mode: when this mode is enabled Redis will append
+# every write operation received in the file appendonly.aof. This file will
+# be read on startup in order to rebuild the full dataset in memory.
+#
+# Note that you can have both the async dumps and the append only file if you
+# like (you have to comment the "save" statements above to disable the dumps).
+# Still if append only mode is enabled Redis will load the data from the
+# log file at startup ignoring the dump.rdb file.
+#
+# IMPORTANT: Check the BGREWRITEAOF to check how to rewrite the append
+# log file in background when it gets too big.
+
+appendonly no
+
+# The name of the append only file (default: "appendonly.aof")
+# appendfilename appendonly.aof
+
+# The fsync() call tells the Operating System to actually write data on disk
+# instead to wait for more data in the output buffer. Some OS will really flush
+# data on disk, some other OS will just try to do it ASAP.
+#
+# Redis supports three different modes:
+#
+# 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 if one second passed since the last fsync. Compromise.
+#
+# The default is "everysec" 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 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
+# everysec.
+#
+# If unsure, use "everysec".
+
+# appendfsync always
+appendfsync everysec
+# appendfsync no
+
+# When the AOF fsync policy is set to always or everysec, and a background
+# saving process (a background save or AOF log background rewriting) is
+# performing a lot of I/O against the disk, in some Linux configurations
+# 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", that in pratical terms means that it is
+# possible to lost up to 30 seconds of log in the worst scenario (with the
+# default Linux settings).
+#
+# If you have latency problems turn this to "yes". Otherwise leave it as
+# "no" that is the safest pick from the point of view of durability.
+no-appendfsync-on-rewrite no
+
+# Automatic rewrite of the append only file.
+# Redis is able to automatically rewrite the log file implicitly calling
+# BGREWRITEAOF when the AOF log size will growth by the specified percentage.
+#
+# This is how it works: Redis remembers the size of the AOF file after the
+# latest rewrite (or if no rewrite 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
+# is reached but it is still pretty small.
+#
+# Specify a precentage of zero in order to disable the automatic AOF
+# rewrite feature.

+
+################################## 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.
+slowlog-log-slower-than 10000
+
+# There is no limit to this length. Just be aware that it will consume memory.
+# You can reclaim memory used by the slow log with SLOWLOG RESET.

+################################ VIRTUAL MEMORY ###############################
+
+### WARNING! Virtual Memory is deprecated in Redis 2.4
+### The use of Virtual Memory is strongly discouraged.
+
+# Virtual Memory allows Redis to work with datasets bigger than the actual
+# amount of RAM needed to hold the whole dataset in memory.
+# In order to do so very used keys are taken in memory while the other keys
+# are swapped into a swap file, similarly to what operating systems do
+# with memory pages.
+#
+# To enable VM just set 'vm-enabled' to yes, and set the following three
+# VM parameters accordingly to your needs.
+
+vm-enabled no
+# vm-enabled yes
+
+# This is the path of the Redis swap file. As you can guess, swap files
+# can't be shared by different Redis instances, so make sure to use a swap
+# file for every redis process you are running. Redis will complain if the
+# swap file is already in use.
+#
+# The best kind of storage for the Redis swap file (that's accessed at random)
+# is a Solid State Disk (SSD).
+#
+# *** WARNING *** if you are using a shared hosting the default of putting
+# the swap file under /tmp is not secure. Create a dir with access granted
+# only to Redis user and configure Redis to create the swap file there.
+vm-swap-file /tmp/redis.swap
+
+# vm-max-memory configures the VM to use at max the specified amount of
+# RAM. Everything that deos not fit will be swapped on disk *if* possible, that
+# is, if there is still enough contiguous space in the swap file.
+#
+# With vm-max-memory 0 the system will swap everything it can. Not a good
+# default, just specify the max amount of RAM you can in bytes, but it's
+# better to leave some margin. For instance specify an amount of RAM
+# that's more or less between 60 and 80% of your free RAM.

+
+# Redis swap files is split into pages. An object can be saved using multiple
+# contiguous pages, but pages can't be shared between different objects.
+# So if your page is too big, small objects swapped out on disk will waste
+# a lot of space. If you page is too small, there is less space in the swap
+# file (assuming you configured the same number of total swap file pages).
+#
+# If you use a lot of small objects, use a page size of 64 or 32 bytes.
+# If you use a lot of big objects, use a bigger page size.
+# If unsure, use the default :)

+#
+# The total swap size is vm-page-size * vm-pages
+#
+# With the default of 32-bytes memory pages and 134217728 pages Redis will
+# use a 4 GB swap file, that will use 16 MB of RAM for the page table.

+# exceed a given threshold. You can configure this limits with the following
+# configuration directives.
+hash-max-zipmap-entries 512
+hash-max-zipmap-value 64

+# Similarly to hashes, small lists are also encoded in a special way in order
+# to save a lot of space. The special representation is only used when
+# you are under the following limits:
+list-max-ziplist-entries 512
+list-max-ziplist-value 64
+
+# Sets have a special encoding in just one case: when a set is composed
+# of just strings that happens to be integers in radix 10 in the range
+# of 64 bit signed integers.
+# The following configuration setting sets the limit in the size of the

+zset-max-ziplist-value 64
+
+# Active rehashing uses 1 millisecond every 100 milliseconds of CPU time in
+# order to help rehashing the main Redis hash table (the one mapping top-level
+# keys to values). The hash table implementation redis uses (see dict.c)
+# performs a lazy rehashing: the more operation you run into an hash table
+# that is rhashing, the more rehashing "steps" are performed, so if the
+# server is idle the rehashing is never complete and some more memory is used
+# by the hash table.
+#
+# The default is to use this millisecond 10 times every second in order to
+# active rehashing the main dictionaries, freeing memory when possible.
+#
+# If unsure:
+# use "activerehashing no" if you have hard latency requirements and it is
+# not a good thing in your environment that Redis can reply form time to time
+# to queries with 2 milliseconds delay.
+#
+# use "activerehashing yes" if you don't have such hard requirements but
+# want to free memory asap when possible.
