dynamodb streams vs kinesis

DynamoDB offers two streaming models for change data capture: Kinesis Data Streams for DynamoDB and DynamoDB Streams. AWS Kinesis Data Streams vs Kinesis Data Firehose. 5. Amazon Kinesis Data Streams for DynamoDB help you to publish item-level changes in any DynamoDB table to a Kinesis data stream of your choice. For no additional cost, customers can build sum, average, count, and other simple analytics functions over a contiguous, non-overlapping time windows (tumbling window) of up to 15 minutes per shard. DynamoDB to Kinesis Stream. DynamoDB Streams. Additionally, you can take advantage of this feature for use cases that require longer data retention on the stream and fan out to multiple concurrent stream readers. Customers can now use AWS Lambda to build analytics workloads for their Amazon Kinesis or Amazon DynamoDB Streams. Kinesis acts as a highly available conduit to stream messages between data producers and data consumers. AWS DynamoDB Streams’s pricing model is also slightly different from Kinesis Streams. Applications can access this log and view the data items as they appeared before and after they were modified, in near real time. Processing DynamoDB streams using the AWS Java DynamoDB streams Kinesis adapter. Whereas Kinesis charges you based on shard hours as well as request count, DynamoDB Streams only charges for the number of read requests. In Cloudwatch I see the 'Try Put to Kinesis Stream' message, but I don't even see the Success/Failure messages. There appears to be about 100 elements coming in at a time. If you use KCL for your Amazon Kinesis Applications, you will be charged for Amazon DynamoDB resources in addition to Amazon Kinesis Data Streams costs. Is there a way to read from Dynamo DB stream with a fixed no of workers and leases without any issue. DynamoDB Streams is a feature of DynamoDB (not a separate service) that makes use of the Kinesis model to capture a time-ordered sequence of item-level modifications in any DynamoDB table. Interestingly, Kinesis Streams is not the only streaming option available on AWS, there is also DynamoDB Streams. To help you choose the right solution for your application, the following table summarizes the features of each streaming model. Interestingly, when processing DynamoDB Streams events with Lambda, the read requests are free! But you indeed has to use a stream name on the table, not the table name. How to process DynamoDB Stream in a Spark streaming application. 0. You don’t have to write or maintain complex code to load and synchronize your data into these services. Increasing DynamoDB Stream + Lambda throughput. 5. By and large, DynamoDB Streams + Lambda works the same way as Kinesis Streams + Lambda. This allows a quick turnaround on tasks like tracking new events of interest, doing ad-hoc analytics, quality assurance, and detecting issues in near real-time. 3. If you enable Enhanced Shard-Level Metrics , you will be charged for Amazon CloudWatch costs associated with enabled shard-level metrics in addition to Amazon Kinesis Data Streams costs. AWS Lambda now allows customers to automatically checkpoint records that have been successfully processed for Amazon Kinesis and Amazon DynamoDB Streams, using a new parameter, FunctionResponseType.When customers set this parameter to “Report Batch Item Failure”, if a batch fails to process, only records after the last successful message are retried. You should mark your question with AWS tags as well because location for the stream name from DynamoDB table is out of Spring Cloud Stream scope.

DynamoDB Streams + Lambda DynamoDB Streams can be used as a like-for-like replacement for Kinesis Streams. This writes successfully to my Kinesis Stream when I have three or four elements in the Lambda test event. Using DynamoDB Streams, Amazon Kinesis Streams, and Lambda together for ad-hoc analytics also means that the processing can begin much faster, as there is no cluster to launch.
