Support DynamoDb transactions

[andrewkrug]

Amazon has just announced this major feature: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/transactions.html

It would be great to ensure that transactions and ACID compliance is supported in Dynalite.

[andrewkrug]

Any traction / support for this?

as of 2019-02-04 dynamodb local supports transactions: https://aws.amazon.com/about-aws/whats-new/2019/02/amazon-dynamodb-local-adds-support-for-transactional-apis-on-demand-capacity-mode-and-20-gsis/

Could we possibly build this as a wrapper on batchGetItems and batchWriteItems? For dev I feel that we don't really need super robust Transactions; mainly we'd just want the method implemented and returning some expected Transactions error messages.

Hi, great project! Any news on this at all... just like @emise says, we don't need anything super robust, but enough to test against. Thanks for the great work!

Came here and was happy to see this was an issue. Any word on if this might occur? Would love to use Dynalite over localstack.

Has anyone found a workaround for this?

Ended up running https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBLocal.DownloadingAndRunning.html locally on port 5555 and start arc with ARC_DB_EXTERNAL=true.

@Xiphe If you want that as an npm dependency with a JS wrapper to start & stop, I can recommend https://github.com/chrisguttandin/dynamo-db-local.

@mantoni Cool! I saw that one and was confused by the relatively low npm downloads of that package. Will give it a try 👍
