Background

Split from:

• Unordered batch commit queue for compaction jobs #3686

Required for:

• State store method to add a transaction from S3 #3899

Description

We'd like to refactor the code that uploads a transaction to S3 to give us the option to do that before we pass the transaction to the transaction log store.

This is so that we can upload a transaction to S3 before we pass it to the state store committer lambda.

Analysis

We'll need to be able to say that the transaction has already been written to S3, and we could move the responsibility for uploading the transaction out of the log store entirely.

Currently the transaction gets uploaded to S3 in DynamoDBTransactionLogStore.setBodyDirectlyOrInS3IfTooBig. We can make a separate class to do that, and we could call that before we call the TransactionLogStore to add the transaction.
