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). JSON values are managed as binary objects, thus allowing Redis-blazing performance.

Quickstart

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

Documentation

Limitations and known issues

• Alpha stage
• AOF rewrite will probably fail for documents with serialization over 0.5GB
• 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 bits integers or doubles, 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:

• jsonsl
• redis
