DynamoDb Item size issue

Question

I have a Dynamodb table called events and i am storing all events information there.

recently i fell into this type of error.

An error occurred (ValidationException) when calling the UpdateItem operation: Item size to update has exceeded the maximum allowed size

Can anyone suggest a solution to resolve this?

Answer 1

There is a record size limit of 400KB, this includes item size and its local secondary indexes. And this can't be increased.

Standard practice to store message in S3 and index in Dynamo. Here is some documentation.
