amazon-dynamodb-streams

AWS DynamoDB provides streams which helps in capturing the table activity. To my understanding the flow of capturing changes in the dream is Stream ARN -> Shards -> shardIterator -> Records . In order for an application to monitor changes on a Dynamo table, it will have to keep on performing the above cycle. I was wondering if this flow can be simplified by hooks that can monitor those changes and trigger, which my application can listen to. I'm aware that there is a AWS Lambda integration which can perform the above cycle and alert, but I was wondering if it can be possible for an application

I am using dynamodb to store configuration for an application, this configuration is likely to be changed a few times a day, and will be in the order of tens of rows. My application will be deployed to a number of EC2 instances. I will eventually write another application to allow management of the configuration, in the meantime configuration is managed by making changes to the table directly in the AWS console. I am trying to use dynamo streams to watch for changes to the configuration, and when the application receives records to process, it simply rereads the entire dynamo table. This works

I'm in the process of writing a Lambda function that processes items from a DynamoDB stream. I thought part of the point behind Lambda was that if I have a large burst of events, it'll spin up enough instances to get through them concurrently, rather than feeding them sequentially through a single instance. As long as two events have a different key, I am fine with them being processed out of order. However, I just read this page on Understanding Retry Behavior , which says: For stream-based event sources (Amazon Kinesis Data Streams and DynamoDB streams), AWS Lambda polls your stream and

I have a Lambda function to which multiple DynamoDB streams are configured as event sources and this is a part of a bigger pipeline. While doing my checks, I found some missing data in one of the downstream components. I want to write a simpler Lambda function which is configured as an event source to one of the earlier mentioned DynamoDB streams. This would cause one of my DynamoDB streams to have two Lambda functions reading from it. I was wondering if this is OK? Are both Lamdba functions guaranteed to receive all records placed in the stream and are there any resource (Read/Write
