Compare data types

Mon, 01 Jan 0001 00:00:00 +0000

Redis provides a wide range of data types to store your data. The following are highly specialized for precise purposes:

Geospatial: store strings with associated coordinates for geospatial queries.
Probabilistic data types: keep approximate counts and other statistics for large datasets.
Time series: store real-valued data points along with the time they were collected.
Vector sets: store strings with associated vector data (and optional metadata) for vector similarity queries.

The remaining data types are more general-purpose:

Redis arrays

Array command summary (view reference, 18 commands)

Redis arrays are sparse, index-addressable data structures that map integer indexes (in the range 0 to 2⁶⁴−1) to string values. Unlike lists, elements are accessed directly by index rather than by position in a sequence, and you can set any index without allocating the gaps between occupied slots. This makes arrays well-suited for timestamped event logs, ring buffers over streaming measurements, sliding-window analytics, and other workloads that involve sparse or high-index access patterns.

Redis geospatial

Mon, 01 Jan 0001 00:00:00 +0000

Geospatial command summary (view reference, 10 commands)

Redis geospatial indexes let you store coordinates and search for them. This data structure is useful for finding nearby points within a given radius or bounding box.

Redis hashes

Mon, 01 Jan 0001 00:00:00 +0000

Hash command summary (view reference, 28 commands)

Redis hashes are record types structured as collections of field-value pairs. You can use hashes to represent basic objects and to store groupings of counters, among other things.

Redis lists

Mon, 01 Jan 0001 00:00:00 +0000

List command summary (view reference, 22 commands)

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

Redis sets

Mon, 01 Jan 0001 00:00:00 +0000

Set command summary (view reference, 17 commands)

A Redis set is an unordered collection of unique strings (members). You can use Redis sets to efficiently:

Redis sorted sets

Mon, 01 Jan 0001 00:00:00 +0000

Sorted set command summary (view reference, 35 commands)

A Redis sorted set is a collection of unique strings (members) ordered by an associated score. When more than one string has the same score, the strings are ordered lexicographically. Some use cases for sorted sets include:
