DynamoDB Source Plugin

Introduction

DynamoDB Batch Source that will read the data items from AWS DynamoDB table and convert each item into the StructuredRecord as per the schema specified by the user, that can be further processed downstream in the pipeline.

Getting Started

Prerequisites

CDAP version 3.5.x or higher.

Building Plugins

You get started with Run transform plugin by building directly from the latest source code::

git clone git@github.com:hydrator/dynamodb-source.git cd dynamodb-source mvn clean package

After the build completes, you will have a JAR for each plugin under each <plugin-name>/target/ directory.

Deploying Plugins

You can deploy a plugin using the CDAP CLI::

load artifact <target/plugin-jar> config-file <resources/plugin-config>

load artifact target/dynamodb-source-plugin-.jar
config-file target/dynamodb-source-plugin-.json

You can build without running tests: mvn clean install -DskipTests

Limitations

• UI doesn't support schema's with hyphens (-), so the plugin currently transforms all the schemas with - into underscores (_). This change will be reverted after this is fixed: https://issues.cask.co/browse/HYDRATOR-1125

Mailing Lists

CDAP User Group and Development Discussions:

• cdap-user@googlegroups.com <https://groups.google.com/d/forum/cdap-user>__

The cdap-user mailing list is primarily for users using the product to develop applications or building plugins for appplications. You can expect questions from users, release announcements, and any other discussions that we think will be helpful to the users.
