Honestly speaking, it's hard to me to get the relationship of these classes and how to use them from this PR. It would be great if there is a simple diagram or something to show the relationship.

Sorry, my previous comment might be unclear. I just read the design document again. The definition of the following terms are still unclear to me, so adding comments about the definitions of xxxxx would be enough:

• batch (I guess ImportTransactionBatch is related)
• task (I guess ImportTaskAction and ImportTaskResult are related)
