# By default kvrocks listens for connections from all the network interfaces
# available on the server. It is possible to listen to just one or multiple
# interfaces using the "bind" configuration directive, followed by one or
# more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1
bind 0.0.0.0

# Accept connections on the specified port, default is 6666.
port 6668

# Close the connection after a client is idle for N seconds (0 to disable)
timeout 0

# The number of worker's threads, increase or decrease it would effect the performance.
workers 8

# The number of replication worker's threads, increase or decrease it would effect the replication performance.
# default is 1
repl-workers 1

# The value should be INFO, WARNING, ERROR, FATAL
# default is INFO
loglevel INFO

# By default kvrocks does not run as a daemon. Use 'yes' if you need it.
# Note that kvrocks will write a pid file in /var/run/kvrocks.pid when daemonized.
daemonize yes 

# 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 kvrocks.
#
# 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 kvrocks 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

# 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 foobared

# Master-Salve replication would check db name is matched. if not, the slave should
# refuse to sync the db from master. Don't use default value, set the db-name to identify
# the cluster.

# The working directory
#
# The DB will be written inside this directory
# Note that you must specify a directory here, not a file name.

# The backup directory
#
# The DB will be written inside this directory
# Note that you must specify a directory here, not a file name.
# backup-dir /tmp/kvrocks/backup

# When running daemonized, kvrocks writes a pid file in ${CONFIG_DIR}/kvrocks.pid by
# default. You can specify a custom pid file location here.
# pidfile /var/run/kvrocks.pid

# 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.
slave-read-only yes

# The slave priority is an integer number published by Kvrocks in the INFO output.
# It is used by Redis Sentinel in order to select a slave to promote into a
# master if the master is no longer working correctly.
#
# A slave with a low priority number is considered better for promotion, so
# for instance if there are three slave with priority 10, 100, 25 Sentinel will
# pick the one with priority 10, that is the lowest.
#
# However a special priority of 0 marks the replica as not able to perform the
# role of master, so a slave with priority of 0 will never be selected by
# Redis Sentinel for promotion.
#
# By default the priority is 100.
slave-priority 100

# TCP listen() backlog.
#
# In high requests-per-second environments you need an high backlog in order
# to avoid slow clients connections issues. Note that the Linux kernel
# will silently truncate it to the value of /proc/sys/net/core/somaxconn so
# make sure to raise both the value of somaxconn and tcp_max_syn_backlog
# in order to Get the desired effect.

# Master-Slave replication. Use slaveof to make a kvrocks instance a copy of
# another kvrocks server. A few things to understand ASAP about kvrocks replication.
#
# 1) Kvrocks 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) Kvrocks 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.

################################## SLOW LOG ###################################

# The Kvrocks 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 Kvrocks
# 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 100000

# 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.
