4 # Note that Redis will write a pid file in /var/run/redis.pid when daemonized.

24 # save <seconds> <changes>
25 #
26 # Will save the DB if both the given number of seconds and the given
27 # number of write operations against the DB occurred.
28 #
29 # In the example below the behaviour will be to save:
30 # after 900 sec (15 min) if at least 1 key changed
31 # after 300 sec (5 min) if at least 10 keys changed
32 # after 60 sec if at least 10000 keys changed

83 # Set the max number of connected clients at the same time. By default there
84 # is no limit, and it's up to the number of file descriptors the Redis process

authored
91 # Don't use more memory than the specified amount of bytes.
92 # When the memory limit is reached Redis will try to remove keys with an
93 # EXPIRE set. It will try to start freeing keys that are going to expire
94 # in little time and preserve keys with a longer time to live.
95 # Redis will also try to remove objects from free lists if possible.
96 #
97 # If all this fails, Redis will start to reply with errors to commands
98 # that will use more memory, like SET, LPUSH, and so on, and will continue
99 # to reply to most read-only commands like GET.

101 # WARNING: maxmemory can be a good idea mainly if you want to use Redis as a
102 # 'state' server or cache, not as a real DB. When Redis is used as a real
103 # database the memory usage will grow over the weeks, it will be obvious if
104 # it is going to use too much memory in the long run, and you'll have the time
105 # to upgrade. With maxmemory after the limit is reached you'll start to get
106 # errors for write operations, and this may even lead to DB inconsistency.

110 ############################## APPEND ONLY MODE ###############################
111
112 # By default Redis asynchronously dumps the dataset on disk. If you can live
113 # with the idea that the latest records will be lost if something like a crash
114 # happens this is the preferred way to run Redis. If instead you care a lot
115 # about your data and don't want to that a single record can get lost you should
116 # enable the append only mode: when this mode is enabled Redis will append
117 # every write operation received in the file appendonly.log. This file will
118 # be read on startup in order to rebuild the full dataset in memory.
119 #
120 # Note that you can have both the async dumps and the append only file if you
121 # like (you have to comment the "save" statements above to disable the dumps).
122 # Still if append only mode is enabled Redis will load the data from the
123 # log file at startup ignoring the dump.rdb file.
