How can I increase the frequency that a lambda pull dynamodb stream?

Question

My lambda is triggered by a dynamodb table stream. Based on the doc: https://docs.aws.amazon.com/lambda/latest/dg/with-ddb.html, Lambda polls shards in your DynamoDB stream for records at a base rate of 4 times per second. When records are available, Lambda invokes your function and waits for the result. If processing succeeds, Lambda resumes polling until it receives more records.

This means I will get about 250 millionseconds latency to trigger my lambda when there is an update happens on dynamodb. Is there a way to improve this pull rate?

Answer 1

You can not change the polling interval, you can only change things like the batch size or the parallelization factor.

Here you can look up the possibilities of configuration, when invoking a lambda through DynamoDBStreams:
