>
> * Entry point for transaction requests
> * Appends transaction control records to the transaction journal
> * Sends transaction control records to data brokers
> * Responsible for expiring transactions
> * Supports fail-over: for which it needs to maintain a transaction HW which
> is the offset of the BEGIN control record of the earliest pending
> transaction. It should checkpoint the HW periodically either to ZK/separate
> topic/offset commit.
> The scope of this ticket will be the basic transaction coordinator
> functionality. E.g., we can just have a basic transaction manager that can
> begin/commit/abort transactions. No expiration, no fail-over. We will add
> failure handling in subsequent jiras.
