JSON with Redis in memory Database – Using redis ReJSON module
Redis is one of the well known and widely used in memory database. Redis is basically a key value data store and support multiple data types include string, list, hashes, set and sortedset. However, the support of JSON was missing in the redis database. Though we could store JSON as a redis string, it defeats the purpose of using json at the first place.
Now with the availability of rejson module, this limitation is no longer applicable. with Redis json module, redis now has a full fledged support of JSON data type in redis. To be able to use redis json module, you need to start the redis server by including the rejson module. Without rejson module the redis json support will not be there.
In this video, I’m using python redis to explain how to use JSON datatype of redis in memory key value data store. I’ve explained the usage of JSON.set and JSON.get as well as JSON.del to create, get and delete the JSON data type.
I’ve also explained in this video that how you can use get to extract part of the json so that we don’t fetch the complete json every time we need a part of data.
