RedisJSON - a JSON data type for Redis

RedisJSON is a Redis module that implements ECMA-404 The JSON Data Interchange Standard as a native data type. It allows storing, updating and fetching JSON values from Redis keys (documents).

Primary features:

• Full support of the JSON standard
• JSONPath-like syntax for selecting element inside documents
• Documents are stored as binary data in a tree structure, allowing fast access to sub-elements
• Typed atomic operations for all JSON values types

Quickstart

1. Launch RedisJSON with Docker
2. Use RedisJSON from any Redis client, e.g.:

Current limitations and known issues

• Internal arrays are not scaled down after deleting items (i.e. free memory isn't reclaimed)
• Numbers are stored using 64-bit integers or doubles, and out of range values are not accepted
