DynamoDB: Time frame to avoid stale read

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"
