RedisJSON2 (RedisJSON nextgen) 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).
- Full support of the JSON standard
- JSONPath syntax for selecting elements 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
- Secondary index support based on RediSearch
docker run -p 6379:6379 --name redis-redisjson redislabs/redisjson2:latest
JSON.INDEX ADD <index> <field> <path>
JSON.QGET <index> <query> <path>
JSON.QSET <index> <query> <path> <json> [NX | XX]
JSON.QDEL <index> <query> <path>
JSON.INDEX DEL <index> <field>
JSON.INDEX INFO <index> <field>
Return value from JSON.QGET is an array of keys and values:
key
json
key
json
In a language such as Java this could be represented as a Map<String, Document>.
A query combining multiple paths:
