The uniform key-value API for SQL and NOSQL databases with Node.js

Using Multiple Databases

If multiple databases are configured, the reading and writing behave as if it is a caching system. When writing to RedKV, the key-value pair gets to write to all databases. When getting a key, RedKV sequentially tries a database from the front of the list, moves on to the next database if the key was not found, and stops until the key is found in a database. After that, the key-value pair is filled to all the databases in front of the list, up to the database where the key is actually found, just like filling a cache.

let kvStore = new RedKV();
kvStore.addStore('redis');
kvStore.addStore('dynamodb', {
        region: "us-east-1",
        endpoint: "https://DynamoDB.us-east-1.amazonaws.com",
        tableName:  'dev.calculator'
    });
