how to create pagination ?

What is the best way to update many-to-many item relationships where data are denormalized?

Can I know how to insert more than 25 items into dynamodb table on a single go?

bkk You won't be able to with the BatchWriteItem call, as it only takes 25 items as a time. That said, some languages have higher-level methods that help split a large amount of items into smaller batches. For example, in Boto3 (Python), there is a Table resource with a batch_writer method --> https://boto3.amazonaws.com...
