In which cases is it advisable to use the JSONB data type in PostgreSQL?

The JSONB data type in PostgreSQL is suitable for the following cases:

• When you need to store semi-structured or dynamic data, whose structure may change over time.
• If you need to perform queries and filtering based on the content of JSON, as JSONB is indexed and supports efficient operations.
• For storing nested objects and arrays with quick access to individual elements.
• When performance is important for reading and updating data in JSON format.

Unlike regular JSON, JSONB stores data in a binary format, which allows for faster operations and the use of indexes.

Example of using JSONB:

CREATE TABLE products (
  id serial PRIMARY KEY,
  specs jsonb
);

INSERT INTO products (specs) VALUES ('{"color": "red", "size": "M"}');

-- Find products with color red
SELECT * FROM products WHERE specs->>'color' = 'red';

Thus, JSONB is suitable for flexible storage and efficient search of JSON data in the database.
