DynamoDB: Time frame to avoid stale read

Question

Hi,

I am writing to dynamoDB using AWS lambda. I am using AWS Console to read data from dynamoDB. But I have seen instances of stale read with latest not records getting updated when trying to pull records under few mins.  What is a safe time interval for data pull which would ensure that latest data is available on read? Would 30 mins be a safe interval?

The below is from AWS site: Just want to understand how recent is recent here.
"When you read data from a DynamoDB table, the response might not reflect the results of a recently completed write operation. The response might include some stale data"

Answer

30 Minutes is more than reasonable. Once you get the status code of 200 back from your Lambda function, the web console should be up to date in seconds. 5 seconds would be enough to wait in normal circumstances, as long as you have received 200 from Lambda.
