valkey-data-types - Man Page

valkey-strings(7) are the most basic Valkey data type, representing a sequence of bytes. For more information, see:

• valkey-strings(7) Overview of Strings
• valkey-commands(7) String command reference

valkey-lists(7) are lists of strings sorted by insertion order. For more information, see:

• valkey-lists(7) Overview of Lists
• valkey-commands(7) List command reference

valkey-sets(7) are unordered collections of unique strings that act like the sets from your favorite programming language (for example, Java HashSets\c , https://docs.python.org/3.10/library/stdtypes.html#set-types-set-frozenset Python sets\c , and so on). With a Set, you can add, remove, and test for existence in O(1) time (in other words, regardless of the number of set elements). For more information, see:

• valkey-sets(7) Overview of Sets
• valkey-commands(7) Set command reference

valkey-hashes(7) are record types modeled as collections of field-value pairs. As such, Hashes resemble Python dictionaries\c , Java HashMaps\c , and Ruby hashes\c . For more information, see:

• valkey-hashes(7) Overview of Hashes
• valkey-commands(7) Hashes command reference

valkey-sorted-sets(7) are collections of unique strings that maintain order by each string’s associated score. For more information, see:

• valkey-sorted-sets(7) Overview of Sorted Sets
• valkey-commands(7) Sorted Set command reference

A valkey-streams-intro(7) Stream is a data structure that acts like an append-only log. Streams help record events in the order they occur and then syndicate them for processing. For more information, see:

• valkey-streams-intro(7) Overview of Streams
• valkey-commands(7) Streams command reference

valkey-geospatial(7) Geospatial indexes are useful for finding locations within a given geographic radius or bounding box. For more information, see:

• valkey-geospatial(7) Overview of Geospatial indexes
• valkey-commands(7) Geospatial indexes command reference

valkey-bitmaps(7) let you perform bitwise operations on strings. For more information, see:

• valkey-bitmaps(7) Overview of Bitmaps
• valkey-commands(7) Bitmap command reference

valkey-bitfields(7) efficiently encode multiple counters in a string value. Bitfields provide atomic get, set, and increment operations and support different overflow policies. For more information, see:

• valkey-bitfields(7) Overview of Bitfields
• The BITFIELD command.

The valkey-hyperloglogs(7) HyperLogLog data structures provide probabilistic estimates of the cardinality (i.e., number of elements) of large sets. For more information, see:

• valkey-hyperloglogs(7) Overview of HyperLogLog
• valkey-commands(7) HyperLogLog command reference

To extend the features provided by the included data types, use one of these options:

1. Write your own custom valkey-programmability(7) server-side functions in Lua.
2. Write your own Valkey module using the valkey-modules-intro(7) modules API or check out the community-supported modules\c .
