# 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 ::1
bind 127.0.0.1
# Unix socket.
#
# Specify the path for the unix socket that will be used to listen for
# incoming connections. There is no default, so kvrocks will not listen
# on a unix socket when not specified.
#
# unixsocket /tmp/kvrocks.sock
# unixsocketperm 777
# Accept connections on the specified port, default is 6666.
port 6383
# 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
# 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 no
# Kvrocks implements cluster solution that is similar with redis cluster solution.
# You can get cluster information by CLUSTER NODES|SLOTS|INFO command, it also is
# adapted to redis-cli, redis-benchmark, redis cluster SDK and redis cluster proxy.
# But kvrocks doesn't support to communicate with each others, so you must set
# cluster topology by CLUSTER SETNODES|SETNODEID commands, more details: #219.
#
# PLEASE NOTE:
# If you enable cluster, kvrocks will encode key with its slot id calculated by
# CRC16 and modulo 16384, endoding key with its slot id makes it efficient to
# migrate keys based on slot. So if you enabled at first time, cluster mode must
# not be disabled after restarting, and vice versa. That is to say, data is not
# compatible between standalone mode with cluster mode, you must migrate data
# if you want to change mode, otherwise, kvrocks will make data corrupt.
#
# Default: no
cluster-enabled no
# Set the max number of connected clients at the same time. By default
# this limit is set to 10000 clients, however if the server is not
# able to configure the process file limit to allow for the specified limit
# the max number of allowed clients is set to the current file limit
#
# Once the limit is reached the server will close all the new connections sending
# an error 'max number of clients reached'.
#
maxclients 10000
# 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 "masterauth" 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.
dir /home/aurelien/git/ail-framework/DATA_KVROCKS
# You can configure where to store your server logs by the log-dir.
# If you don't specify one, we will use the above `dir` as our default log directory.
# We also can send logs to stdout/stderr is as simple as:
#
# log-dir stdout
# 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
pidfile ""
# 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.
tcp-backlog 511
# If the master is an old version, it may have specified replication threads
# that use 'port + 1' as listening port, but in new versions, we don't use
# extra port to implement replication. In order to allow the new replicas to
# copy old masters, you should indicate that the master uses replication port
# or not.
# If yes, that indicates master uses replication port and replicas will connect
# to 'master's listening port + 1' when synchronization.
# If no, that indicates master doesn't use replication port and replicas will
# connect 'master's listening port' when synchronization.
master-use-repl-port no
# Currently, master only checks sequence number when replica asks for PSYNC,
# that is not enough since they may have different replication history even
# the replica asking sequence is in the range of the master current WAL.
#
# We design 'Replication Sequence ID' PSYNC, we add unique replication id for
# every write batch (the operation of each command on the storage engine), so
# the combination of replication id and sequence is unique for write batch.
# The master can identify whether the replica has the same replication history
# by checking replication id and sequence.
#
# By default, it is not enabled since this stricter check may easily lead to
# full synchronization.
use-rsid-psync no
# 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.
#
# slaveof <masterip> <masterport>
# slaveof 127.0.0.1 6379
# When a slave loses its 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 date 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
# To guarantee slave's data safe and serve when it is in full synchronization
# state, slave still keep itself data. But this way needs to occupy much disk
# space, so we provide a way to reduce disk occupation, slave will delete itself
# entire database before fetching files from master during full synchronization.
# If you want to enable this way, you can set 'slave-delete-db-before-fullsync'
# to yes, but you must know that database will be lost if master is down during
# full synchronization, unless you have a backup of database.
#
# This option is similar redis replicas RDB diskless load option:
# repl-diskless-load on-empty-db
#
# Default: no
slave-empty-db-before-fullsync no
# If replicas need full synchronization with master, master need to create
# checkpoint for feeding replicas, and replicas also stage a checkpoint of
# the master. If we also keep the backup, it maybe occupy extra disk space.
# You can enable 'purge-backup-on-fullsync' if disk is not sufficient, but
# that may cause remote backup copy failing.
#
# Default: no
purge-backup-on-fullsync no

################################## SLOW LOG ###################################
# The Kvrocks Slow Log is a mechanism 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 -1 value 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.
slowlog-max-len 128
# If you run kvrocks from upstart or systemd, kvrocks can interact with your
# supervision tree. Options:
# supervised no - no supervision interaction
# supervised upstart - signal upstart by putting kvrocks into SIGSTOP mode
# supervised systemd - signal systemd by writing READY=1 to $NOTIFY_SOCKET
# supervised auto - detect upstart or systemd method based on
# UPSTART_JOB or NOTIFY_SOCKET environment variables
# Note: these supervision methods only signal "process is ready."
# They do not enable continuous liveness pings back to your supervisor.
supervised no
################################## PERF LOG ###################################
# The Kvrocks Perf Log is a mechanism to log queries' performance context that
# exceeded a specified execution time. This mechanism uses rocksdb's
# Perf Context and IO Stats Context, Please see:
# https://github.com/facebook/rocksdb/wiki/Perf-Context-and-IO-Stats-Context
#
# This mechanism is enabled when profiling-sample-commands is not empty and
# profiling-sample-ratio greater than 0.
# It is important to note that this mechanism affects performance, but it is
# useful for troubleshooting performance bottlenecks, so it should only be
# enabled when performance problems occur.
# The name of the commands you want to record. Must be original name of
# commands supported by Kvrocks. Use ',' to separate multiple commands and
# use '*' to record all commands supported by Kvrocks.
# Example:
# - Single command: profiling-sample-commands get
# - Multiple commands: profiling-sample-commands get,mget,hget
#
# Default: empty
# profiling-sample-commands ""
# Ratio of the samples would be recorded. We simply use the rand to determine
# whether to record the sample or not.
#
# Default: 0
profiling-sample-ratio 0
# There is no limit to this length. Just be aware that it will consume memory.
# You can reclaim memory used by the perf log with PERFLOG RESET.
#
# Default: 256
profiling-sample-record-max-len 256
# profiling-sample-record-threshold-ms use to tell the kvrocks when to record.
#
# Default: 100 millisecond
profiling-sample-record-threshold-ms 100
################################## CRON ###################################
# Compact Scheduler, auto compact at schedule time
# time expression format is the same as crontab(currently only support * and int)
# e.g. compact-cron 0 3 * * * 0 4 * * *
# would compact the db at 3am and 4am everyday
# compact-cron 0 3 * * *
# The hour range that compaction checker would be active
# e.g. compaction-checker-range 0-7 means compaction checker would be worker between
# 0-7am every day.
compaction-checker-range 0-7
# Bgsave scheduler, auto bgsave at schedule time
# time expression format is the same as crontab(currently only support * and int)
# e.g. bgsave-cron 0 3 * * * 0 4 * * *
# would bgsave the db at 3am and 4am everyday
# Command renaming.
#
# It is possible to change the name of dangerous commands in a shared
# environment. For instance the KEYS command may be renamed into something
# hard to guess so that it will still be available for internal-use tools
# but not available for general clients.
#
# Example:
#
# rename-command KEYS b840fc02d524045429941cc15f59e41cb7be6c52
#
# It is also possible to completely kill a command by renaming it into
# an empty string:
#
# rename-command KEYS ""
# The key-value size may so be quite different in many scenes, and use 256MiB as SST file size
# may cause data loading(large index/filter block) ineffective when the key-value was too small.
# kvrocks supports user-defined SST file in config(rocksdb.target_file_size_base),
# but it still too trivial and inconvenient to adjust the different sizes for different instances.
# so we want to periodic auto-adjust the SST size in-flight with user avg key-value size.
#
# If enabled, kvrocks will auto resize rocksdb.target_file_size_base
# and rocksdb.write_buffer_size in-flight with user avg key-value size.
# Please see #118.
#
# Default: yes
auto-resize-block-and-sst yes
################################ MIGRATE #####################################
# If the network bandwidth is completely consumed by the migration task,
# it will affect the availability of kvrocks. To avoid this situation,
# migrate-speed is adpoted to limit the migrating speed.
# Migrating speed is limited by controling the duraiton between sending data,
# the duation is calculated by: 1000000 * migrate-pipeline-size / migrate-speed (us).
# Value: [0,INT_MAX], 0 means no limit
#
# Default: 4096
migrate-speed 4096
# In order to reduce data transimission times and improve the efficiency of data migration,
# pipeline is adopted to send multiple data at once. Pipeline size can be set by this option.
# Value: [1, INT_MAX], it can't be 0
#
# Default: 16
migrate-pipeline-size 16
# In order to reduce the write forbidden time during migrating slot, we will migrate the incremetal
# data sevral times to reduce the amount of incremetal data. Until the quantity of incremetal
# data is reduced to a certain threshold, slot will be forbidden write. The threshold is set by
# this option.
# Value: [1, INT_MAX], it can't be 0
#

# In order to limit the size of WALs, RocksDB uses DBOptions::max_total_wal_size
# as the trigger of column family flush. Once WALs exceed this size, RocksDB
# will start forcing the flush of column families to allow deletion of some
# oldest WALs. This config can be useful when column families are updated at
# non-uniform frequencies. If there's no size limit, users may need to keep
# really old WALs when the infrequently-updated column families hasn't flushed
# for a while.
#
# In kvrocks, we use multiple column families to store metadata, subkeys, etc.
# If users always use string type, but use list, hash and other complex data types
# infrequently, there will be a lot of old WALs if we don't set size limit
# (0 by default in rocksdb), because rocksdb will dynamically choose the WAL size
# limit to be [sum of all write_buffer_size * max_write_buffer_number] * 4 if set to 0.
#
# Moreover, you should increase this value if you already set rocksdb.write_buffer_size
# to a big value, to avoid influencing the effect of rocksdb.write_buffer_size and

# BlobDB(key-value separation) is essentially RocksDB for large-value use cases.
# Since 6.18.0, The new implementation is integrated into the RocksDB core.
# When set, large values (blobs) are written to separate blob files, and only
# pointers to them are stored in SST files. This can reduce write amplification
# for large-value use cases at the cost of introducing a level of indirection
# for reads. Please see: https://github.com/facebook/rocksdb/wiki/BlobDB.
#
# Note that when enable_blob_files is set to yes, BlobDB-related configuration
# items will take effect.
#
# Default: no
rocksdb.enable_blob_files no
# The size of the smallest value to be stored separately in a blob file. Values
# which have an uncompressed size smaller than this threshold are stored alongside
# the keys in SST files in the usual fashion.
#
# Default: 4096 byte, 0 means that all values are stored in blob files
rocksdb.min_blob_size 4096
# The size limit for blob files. When writing blob files, a new file is
# opened once this limit is reached.
#
# Default: 268435456 bytes
rocksdb.blob_file_size 268435456
# Enables garbage collection of blobs. Valid blobs residing in blob files
# older than a cutoff get relocated to new files as they are encountered
# during compaction, which makes it possible to clean up blob files once
# they contain nothing but obsolete/garbage blobs.
# See also rocksdb.blob_garbage_collection_age_cutoff below.
#
# Default: yes
rocksdb.enable_blob_garbage_collection yes
# The percentage cutoff in terms of blob file age for garbage collection.
# Blobs in the oldest N blob files will be relocated when encountered during
# compaction, where N = (garbage_collection_cutoff/100) * number_of_blob_files.
# Note that this value must belong to [0, 100].
#
# Default: 25
rocksdb.blob_garbage_collection_age_cutoff 25
# The purpose of following three options are to dynamically adjust the upper limit of
# the data that each layer can store according to the size of the different
# layers of the LSM. Enabling this option will bring some improvements in
# deletion efficiency and space amplification, but it will lose a certain
# amount of read performance.

# https://github.com/facebook/rocksdb/wiki/Leveled-Compaction#levels-target-size
#
# Default: no
rocksdb.level_compaction_dynamic_level_bytes no
# The total file size of level-1 sst.
#
# Default: 268435456 bytes
rocksdb.max_bytes_for_level_base 268435456
# Multiplication factor for the total file size of L(n+1) layers.
# This option is a double type number in RocksDB, but kvrocks is
# not support double data type number yet, so we use int data
# number instead of double currently.
