DynamoDB Streams exception

Question

I am trying to implement the Dynamodb Streams Java example from AWS. I get the following 2 errors repeated several times and then the program completes as expected. Any ideas what the cause is?

[error] c.a.s.k.c.l.w.ShardSyncTask - Caught exception while sync'ing Kinesis shards and leases

Answer 1

We had the same problem, and it turned out we where missing the region in our settings, explicitly setting the region made it work.

For dynamodb-local you don't need a region though, so using that it will work without the region, and then when you deploy it in AWS you will get the above error.

Answer 2

The answer provided by @mikeal-sundberg didn't work for me, I eventually figured it was down to a difference between provided endpoints in AWS vs Dynamo local.

With Dynamo local you can use the same endpoint for the standard Dynamo client as well as the AmazonDynamoDBStreams client. When deployed, the AmazonDynamoDBStreams client needs a streams specific endpoint such as https://streams.dynamodb.eu-west-1.amazonaws.com .
