The dynamodb source enables change data capture (CDC) on Amazon DynamoDB tables. It can receive table events, such as create, update, or delete, using DynamoDB streams and supports initial snapshots using point-in-time recovery (PITR).

The source includes two ingestion options to stream DynamoDB events:

  1. A full initial snapshot using PITR gets an initial snapshot of the current state of the DynamoDB table. This requires the PITR Snapshots and DyanmoDB option enabled on your DynamoDB table.
  2. Stream events from DynamoDB streams without full initial snapshots. This is useful if you already have a snapshot mechanism within your pipelines. This requires that the DynamoDB stream option is enabled on the DynamoDB table.


The following example pipeline specifies DynamoDB as a source. It ingests data from a DyanmoDB table named table-a through a PITR snapshot. It also indicates the start_position, which tells the pipeline how to read DynamoDB stream events:

version: "2"
        - table_arn: "arn:aws:dynamodb:us-west-2:123456789012:table/table-a"
            s3_bucket: "test-bucket"
            s3_prefix: "myprefix"
            start_position: "LATEST" # Read latest data from streams (Default)
        region: "us-west-2"
        sts_role_arn: "arn:aws:iam::123456789012:role/my-iam-role"

Configuration options

The following tables describe the configuration options for the dynamodb source.

Option Required Type Description
aws Yes AWS The AWS configuration. See aws for more information.
acknowledgments No Boolean When true, enables s3 sources to receive end-to-end acknowledgments when events are received by OpenSearch sinks.
shared_acknowledgement_timeout No Duration The amount of time that elapses before the data read from a DynamoDB stream expires when used with acknowledgements. Default is 10 minutes.
s3_data_file_acknowledgment_timeout No Duration The amount of time that elapses before the data read from a DynamoDB export expires when used with acknowledgments. Default is 5 minutes.
tables Yes List The configuration for the DynamoDB table. See tables for more information.


Use the following options in the AWS configuration.

Option Required Type Description
region No String The AWS Region to use for credentials. Defaults to standard SDK behavior to determine the Region.
sts_role_arn No String The AWS Security Token Service (AWS STS) role to assume for requests to Amazon Simple Queue Service (Amazon SQS) and Amazon Simple Storage Service (Amazon S3). Defaults to null, which will use the standard SDK behavior for credentials.
aws_sts_header_overrides No Map A map of header overrides that the AWS Identity and Access Management (IAM) role assumes for the sink plugin.


Use the following options with the tables configuration.

Option Required Type Description
table_arn Yes String The Amazon Resource Name (ARN) of the source DynamoDB table.
export No Export Determines how to export DynamoDB events. For more information, see export.
stream No Stream Determines how the pipeline reads data from the DynamoDB table. For more information, see stream.

Export options

The following options let you customize the export destination for DynamoDB events.

Option Required Type Description
s3_bucket Yes String The destination bucket that stores the exported data files.
s3_prefix No String The custom prefix for the S3 bucket.
s3_sse_kms_key_id No String An AWS Key Management Service (AWS KMS) key that encrypts the export data files. The key_id is the ARN of the KMS key, for example, arn:aws:kms:us-west-2:123456789012:key/0a4bc22f-bb96-4ad4-80ca-63b12b3ec147.
s3_region No String The Region for the S3 bucket.

Stream option

The following option lets you customize how the pipeline reads events from the DynamoDB table.

Option Required Type Description
start_position No String The position from where the source starts reading stream events when the DynamoDB stream option is enabled. LATEST starts reading events from the most recent stream record.
