Calcite DynamoDB Adapter

Calcite DynamoDB Adapter is SQL interface for Amazon DynamoDB.

Make sure you installed Maven and Java8, in the project home directory run maven command:

mvn clean package

Calcite DynamoDB Adapter is build on top of Apache Calcite, when connect it via JDBC, the connect string contains a json model file:

{
  "version": "1.0",
  "defaultSchema": "DEMO",
  "schemas": [
    {
      "name": "DEMO",
      "type": "custom",
      "factory": "calcite.adapter.dynamodb.DynamoDBSchemaFactory",
      "operand": {
        "region": "us-west-2",
        "meta": "meta"
      }
    }
  ]
}

In this json model file, "region": "us-west-2" means DynamoDB region is us-west-2, and "meta": "meta" means the DynamoDB table "meta" stores table metadata.

Then Calcite DynamoDB Adapter will scan DynamoDB table "meta" to generate all of the available tables under DEMO schema.
