@F2006 This test is the one causing the errored emails I think. https://travis-ci.org/awslabs/dynamodb-titan-storage-backend/builds/226407287 shows "Job errored" status, while for the GraphTest ones it only shows "Job failed". Currently this test times out for lack of output. Can you make a PR that causes something to be printed every five minutes or so to the console?

@amcp pull request (https://github.com/awslabs/dynamodb-titan-storage-backend/pull/102) made, will monitor the build and see how it goes: https://travis-ci.org/awslabs/dynamodb-titan-storage-backend/builds/226481447

@F2006 thank you. I reviewed, and now I will sleep, so I will look at your updates in the morning.

Probably fixed in #102, will merge and then enable the MultiStoreTest again
