ReJSON - a JSON data type for Redis

ReJSON 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. Build the ReJSON module library
2. Load ReJSON to Redis
3. Use ReJSON from any Redis client, e.g.:

Current limitations and known issues

• Beta quality
• Searching for object keys is O(N)
• Containers 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

Acknowledgements

ReJSON is developed with <3 at Redis Labs.

ReJSON is made possible only because of the existance of these amazing open source projects:
