ballerinax/persist.inmemory Ballerina library

Overview

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

The In-Memory data store is a simple data store that stores data in memory. This data store is useful for testing purposes.

How to use with bal persist

Integrate to bal build

By default, bal persist utilizes the in-memory data store. Therefore, you do not need to explicitly specify the data store when you integrate to bal build.

1. Initialize bal persist and integrate to bal build using the following command,

   $ bal persist add --module <module_name>
   

2. After defining the entities, build the application using the following command,

   $ bal build
   

One time generation

When using one-time generation, you need to specify the data store.

1. Initialize bal persist using the following command,

   $ bal persist init
   

2. Generate the persist client using the following command,

   $ bal persist generate --datastore inmemory --module <module_name>
   

Supported Ballerina Types

In-memory uses Ballerina tables as the data store. Therefore, all types supported by Ballerina are supported with bal persist when in-memory is used as the data source.

Configuration

The In-Memory data store does not require any configuration.
