RedisJSON

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 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/rejson:latest

Then, build as usual:

cargo build --release

When running the tests, you need to explicitly specify the test feature to disable use of the Redis memory allocator when testing:

cargo test --features test

If you forget to do this, you'll see an error mentioning signal: 4, SIGILL: illegal instruction.

redis-server --loadmodule ./target/release/librejson.so

redis-server --loadmodule ./target/release/librejson.dylib

Some languages have client libraries that provide support for RedisJSON's commands:
