Ballerina Persist - In-Memory Library

This library provides in-memory tables support for the bal persist feature, which provides functionality to store and query data conveniently through a data model.

The persist command will make it easy to enable bal persist feature in a Ballerina project. With this support, users need not worry about the persistence in a project. Users can define an entity data model, validate the model and generate persist clients for Inmemory tables, which provide convenient APIs to store and query data in a data store.

For more information, see persist.inmemory API Documentation.
