Does dynamodb have maximum size limitation on query input?

I know dynamodb query has limitation on maximum response data size is 1MB. But does it have limitation on the input filter parameter? I may need to send a filter expression has a long list of values, I wonder whether it works without limtation?

Solution

  • As per AWS documentation:

    The maximum length of any expression string is 4 KB, which includes ProjectionExpression, ConditionExpression, UpdateExpression, and FilterExpression.

    Check more details here: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Constraints.html#limits-expression-parameters

    Additional DynamoDB service limits are documented at https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ServiceQuotas.html#limits-expression-parameters

    hope it answer your question.
