I'm noticing my dynamodb tests are flaky because of what I assume is eventual consistency. Eg a simple test that creates and entity and then reads it out fails randomly. How are other people thinking about this?

Are they repeatably/consistently flaky ? 😅 If so you might want to try transactions against that same infrastructure just to check (changing only one variable in the experiment).

I guess I just should be using returnValues instead of requerying

If you'e testing writes, why not.

Using strong consistency flag on read might also help.

weirdly the strong consistency flag didn't fix it but need to test further

Wouldn't you need to use a transaction to guarantee it'd be immediately readable after the write?

hmm i might be wrong.. this is what I gather from the doc

A strongly consistent read in Amazon DynamoDB returns a result that reflects all writes that received a successful response prior to the read.

And it’s been pretty stable in my experience without using transaction.

I use return values instead of requerying on a put to a dynamo table. For gets, I run a script to seed the tables so they have data for reads.

^ this is exactly what I setup 👍🏽
