+# 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.
 
-# When disk store is active Redis works as an on-disk database, where memory
-# is only used as a object cache.
-#
-# This mode is good for datasets that are bigger than memory, and in general
-# when you want to trade speed for:
-#
-#  - less memory used
-#  - immediate server restart
-#  - per key durability, without need for backgrond savig
-#
-# On the other hand, with disk store enabled MULTI/EXEC are no longer
-# transactional from the point of view of the persistence on disk, that is,
-# Redis transactions will still guarantee that commands are either processed
-# all or nothing, but there is no guarantee that all the keys are flushed
-# on disk in an atomic way.
-#
-# Of course with disk store enabled Redis is not as fast as it is when
-# working with just the memory back end.
+# 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.
