Redis Commands#

Core Commands#

The following functions can be used to replicate their equivalent Redis command. Generally they can be used as functions on your redis connection. For the simplest example, see below:

Getting and settings data in redis:

r = redis.Redis(decode_responses=True)
r.set('mykey', 'thevalueofmykey')
r.get('mykey')

Create or update an ACL user.

Create or update the ACL for username. If the user already exists, the existing ACL is completely overwritten and replaced with the specified values.

enabled is a boolean indicating whether the user should be allowed to authenticate or not. Defaults to False.

nopass is a boolean indicating whether the can authenticate without a password. This cannot be True if passwords are also specified.

passwords if specified is a list of plain text passwords to add to or remove from the user. Each password must be prefixed with a ‘+’ to add or a ‘-’ to remove. For convenience, the value of passwords can be a simple prefixed string when adding or removing a single password.

hashed_passwords if specified is a list of SHA-256 hashed passwords to add to or remove from the user. Each hashed password must be prefixed with a ‘+’ to add or a ‘-’ to remove. For convenience, the value of hashed_passwords can be a simple prefixed string when adding or removing a single password.

commands if specified is a list of strings representing command permissions. Each string must be prefixed with either a ‘+’ to add the command permission or a ‘-’ to remove the command permission.

keys if specified is a list of key patterns to grant the user access to. Keys patterns allow ‘*’ to support wildcard matching. For example, ‘*’ grants access to all keys while ‘cache:*’ grants access to all keys that are prefixed with ‘cache:’. keys should not be prefixed with a ‘~’.

reset is a boolean indicating whether the user should be fully reset prior to applying the new ACL. Setting this to True will remove all existing passwords, flags and privileges from the user and then apply the specified rules. If this is False, the user’s existing passwords, flags and privileges will be kept and any new specified rules will be applied on top.

By default, LPOS returns the position of the first occurrence of value in the list. When rank 2, LPOS returns the position of the second value in the list. If rank is negative, LPOS searches the list in reverse. For example, -1 would return the position of the last occurrence of value and -2 would return the position of the next to last occurrence of value.

If specified, count indicates that LPOS should return a list of up to count positions. A count of 2 would return a list of up to 2 positions. A count of 0 returns a list of all positions matching value. When count is specified and but value does not exist in the list, an empty list is returned.

If specified, maxlen indicates the maximum number of list elements to scan. A maxlen of 1000 will only return the position(s) of items within the first 1000 entries in the list. A maxlen of 0 (the default) will scan the entire list.

Set any number of element-name, score pairs to the key name. Pairs are specified as a dict of element-names keys to score values.

nx forces ZADD to only create new elements and not to update scores for elements that already exist.

xx forces ZADD to only update scores of elements that already exist. New elements will not be added.

ch modifies the return value to be the numbers of elements changed. Changed elements include new elements that were added and elements whose scores changed.

incr modifies ZADD to behave like ZINCRBY. In this mode only a single element/score pair can be specified and the score is the amount the existing score will be incremented by. When using this mode the return value of ZADD will be the new score of the element.

LT Only update existing elements if the new score is less than the current score. This flag doesn’t prevent adding new elements.

GT Only update existing elements if the new score is greater than the current score. This flag doesn’t prevent adding new elements.

The return value of ZADD varies based on the mode specified. With no options, ZADD returns the number of new elements added to the sorted set.

NX, LT, and GT are mutually exclusive options.

Sentinel Commands#

class redis.commands.sentinel.SentinelCommands[source]#

A class containing the commands specific to redis sentinel. This class is to be used as a mixin.

sentinel(*args)[source]#: Redis Sentinel’s SENTINEL command.

sentinel_ckquorum(new_master_name)[source]#

Check if the current Sentinel configuration is able to reach the quorum needed to failover a master, and the majority needed to authorize the failover.

This command should be used in monitoring systems to check if a Sentinel deployment is ok.

sentinel_failover(new_master_name)[source]#: Force a failover as if the master was not reachable, and without asking for agreement to other Sentinels (however a new version of the configuration will be published so that the other Sentinels will update their configurations).

sentinel_flushconfig()[source]#

Force Sentinel to rewrite its configuration on disk, including the current Sentinel state.

Normally Sentinel rewrites the configuration every time something changes in its state (in the context of the subset of the state which is persisted on disk across restart). However sometimes it is possible that the configuration file is lost because of operation errors, disk failures, package upgrade scripts or configuration managers. In those cases a way to to force Sentinel to rewrite the configuration file is handy.

This command works even if the previous configuration file is completely missing.

sentinel_get_master_addr_by_name(service_name)[source]#: Returns a (host, port) pair for the given service_name

sentinel_master(service_name)[source]#: Returns a dictionary containing the specified masters state.

sentinel_masters()[source]#: Returns a list of dictionaries containing each master’s state.

sentinel_monitor(name, ip, port, quorum)[source]#: Add a new master to Sentinel to be monitored

sentinel_remove(name)[source]#: Remove a master from Sentinel’s monitoring

sentinel_reset(pattern)[source]#

This command will reset all the masters with matching name. The pattern argument is a glob-style pattern.

The reset process clears any previous state in a master (including a failover in progress), and removes every slave and sentinel already discovered and associated with the master.

sentinel_sentinels(service_name)[source]#: Returns a list of sentinels for service_name

sentinel_set(name, option, value)[source]#: Set Sentinel monitoring parameters for a given master

sentinel_slaves(service_name)[source]#: Returns a list of slaves for service_name

Redis Cluster Commands#

The following Redis commands are available within a Redis Cluster. Generally they can be used as functions on your redis connection.

class redis.commands.cluster.RedisClusterCommands(*args, **kwargs)[source]#
