JSON Support in Scylla

JSON in Scylla

Beginning with version 2.3, Scylla Open Source supports the Javascript Object Notation (JSON) format. That includes inserting JSON documents, retrieving data in JSON and providing helper functions to transform native CQL types into JSON and vice versa. Also note that schemas are still enforced for all operations — one cannot just insert random JSON documents into a table. The new API is simply a convenient way of working with JSON without having to convert everything back and forth client-side. JSON support consists of CQL statements and functions, described here, one by one, with examples. You can use the following code […]
