Redis lists

Introduction to Redis lists

Redis lists are linked lists of string values. Redis lists are frequently used to:

• Implement stacks and queues.
• Build queue management for background worker systems.

Basic commands

• LPUSH adds a new element to the head of a list; RPUSH adds to the tail.
• LPOP removes and returns an element from the head of a list; RPOP does the same but from the tails of a list.
• LLEN returns the length of a list.
• LMOVE atomically moves elements from one list to another.
• LRANGE extracts a range of elements from a list.
• LTRIM reduces a list to the specified range of elements.

Blocking commands

Lists support several blocking commands. For example:

• BLPOP removes and returns an element from the head of a list. If the list is empty, the command blocks until an element becomes available or until the specified timeout is reached.
• BLMOVE atomically moves elements from a source list to a target list. If the source list is empty, the command will block until a new element becomes available.

See the complete series of list commands.

Examples

• Treat a list like a queue (first in, first out):

  >_ Redis CLI

  > LPUSH bikes:repairs bike:1
  (integer) 1
  > LPUSH bikes:repairs bike:2
  (integer) 2
  > RPOP bikes:repairs
  "bike:1"
  > RPOP bikes:repairs
  "bike:2"

  C# Quick-Start

• To limit the length of a list you can call LTRIM:

  >_ Redis CLI

  > RPUSH bikes:repairs bike:1 bike:2 bike:3 bike:4 bike:5
  (integer) 5
  > LTRIM bikes:repairs 0 2
  OK
  > LRANGE bikes:repairs 0 -1
  1) "bike:1"
  2) "bike:2"
  3) "bike:3"
