## Overview

This adapter allows you to access document data that is stored in a [Amazon's DynamoDB](https://aws.amazon.com/dynamodb/) from inside of the Exasol analytical database. It abstracts over the different interfaces so that you can access the document data just like any regular Exasol table.

## Features

* Read access to data stored in DynamoDB

* Maps unstructured document data to Exasol tables that you can access using regular SQL statements

* Pushes down queries to the remote source

* Distributes the data loading over the whole Exasol Cluster, what makes queries more than six times faster compared to using a JDBC adapter

* Flexible definition of the schema mapping using the [Exasol Document Mapping Language (EDML)](https://github.com/exasol/virtual-schema-common-document/blob/main/doc/user_guide/edml_user_guide.md)

## Limitations

* The adapter does not support comparisons between two columns.
