Is your Feature Request related to a problem? I don't seem to have a way to get at this DynamoDbRetryPolicy class, for example, because it's marked as an ... My understanding is Dynamodb stream lambda ensures in-order processing at the table partition-key level. It would be great if I could implement a partial infinite blocking for a specific sub-stream (aka a table partition-key stream). I'm thinking to use: MaximumRecordAgeInSeconds to limit the retry logic (up to a few hours to allow hotfixes)If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we strongly recommend that you use an exponential backoff algorithm . If you retry the batch operation immediately, the underlying read or write requests can still fail due to throttling on the individual tables.Retry with options:ErrorEquals,IntervalSeconds, MaxAttempts,BackoffRate link. A lambda function can be configured as destinaton for CodeCommit trigger. Note that this canbe done from lambda console not from CodeCommit event notification console (as of March 2021) Lambda function default timeout is 3 secs, but can be extended upto 15 minsBy default, the DynamoDB write operations (PutItem, UpdateItem, DeleteItem) are unconditional: each of these operations will overwrite an existing item that has the specified primary key. DynamoDB provides mechanism to implement conditional writes that ensures no other write request interferes with the current operation.In SixNines.io, one of my Ruby pet web apps, I'm using DynamoDB, a NoSQL cloud database by AWS.It works like a charm, but the problem is that it's not so easy to create an integration test, to ...DynamoDB is an easy-to-use NoSQL database available only on AWS.

Using optimistic_concurrency_control via delta streamer requires adding the above configs to the properties file that can be passed to the job.To have Amazon DynamoDB return fewer items, you can provide a ScanFilter. If the total number of scanned items exceeds the maximum data set size limit of 1 MB, the scan stops and results are returned to the user with a LastEvaluatedKey to continue the scan in a subsequent operation. The results also include the number of items exceeding the limit. DynamoDB allows multiple threads to update the item. However, when a transaction detects that another thread has already modified the data, it aborts the transaction and rolls the data back. It monitors other threads making changes to the data. Therefore, it has a higher performance overhead than Optimistic Locking.Applying the pub-sub and push-pull messaging patterns with AWS Lambda. Publish-sub is a messaging pattern where publishers and subscribers are decoupled through an intermediary broker (ZeroMQ, RabbitMQ, SNS, etc.) SNS will make 3 attempts for your function to process a message before sending it to a Dead Letter Queue (DLQ) If the burst in ...To have Amazon DynamoDB return fewer items, you can provide a ScanFilter.
