#DOCKER LOCAL DYNAMODB STREAMS HOW TO#

The most common approaches use AWS LambdaВ or a standalone application that uses the Kinesis Client Library (KCL) with the DynamoDB Streams Kinesis Adapter. You can process DynamoDB streams in multiple ways.

NEW_AND_OLD_IMAGES-Both the new and the old images of the item.

OLD_IMAGE-The entire item as it appears before it was modified.

NEW_IMAGE-The entire item as it appears after it was modified.

KEYS_ONLY-Only the key attributes of the modified item.

To read and process DynamoDB Streams records, your application must access a DynamoDB Streams endpoint in the same Region.ДЇigure 1: Accessing DynamoDB and DynamoDB StreamsДynamoDB Streams supports the following streamВ recordВ views: To work with database tables and indexes, your application must access a DynamoDB endpoint.

Applications can access a series of stream records, which contain an item change, from a DynamoDB stream in near real time.ДЄWS maintains separate endpoints for DynamoDB and DynamoDB Streams. When you enable DynamoDB Streams, it captures a time-ordered sequence of item-level modifications in a DynamoDB table and durably stores the information for up to 24 hours. DynamoDB Streams is a powerful service that you can combine with other AWS services to solve many similar issues. You can use DynamoDB Streams to address all these use cases.

How do you replicate data across multiple tables (similar to that of materialized views/streams/replication in relational data stores)?.

How do you trigger an event based on a particular item change?.

How do you set up a relationship across multiple tables in which, based on the value of an item from one table, you update the item in a second table?.

We will consider how to manage the following scenarios:

This post describes some common use cases you might encounter, along with their design options and solutions, when migrating data from relational data stores to Amazon DynamoDB. September 8, 2021: Amazon Elasticsearch Service has been renamed to Amazon OpenSearch Service.
