Inserting JSON data with the INSERT command for testing queries.
In a production database, inserting columns and column values programmatically is more practical than using cqlsh. The CQL INSERT commands supports JSON to provide a manual testing from the cqlsh command line utility.
INSERT INTO [keyspace_name.]table_name JSON '{"column_name": value [,…]}' [DEFAULT UNSET];
Note: Enclose all values other than numbers in double quotes. Booleans, UUID, and other data types typically recognized in cqlsh must be in double quotes.
