Improving DynamoDB Write Operation

Question

I am trying to call dynamodb write operation to write around 60k records.

I have tried to put 1000 write capacity unites for Provisioned Write capacity. But my write operation is still taking lot of time. Also when I check the metrics I can still see the consumed Write capacity units as around 10 per seconds.

My record size is definitely less than 1KB.

Is there a way we can speed up the write operation for dynamodb?

Answer 1

So here is what I figured out.

I changed my call to use batchWrite and my consumed Write capacity units has increased significantly upto 286 write capacity units. Also the complete write operation finished within couple of minutes. As mentioned in all above answers using putItem to load large number of data has the latency issues and it affects your consumed capacities. It is always better to batchWrite.
