Implement a Multi-Partition Transactional Producer with Two-Phase Commit

Problem Overview

Kafka Transactions guarantee atomic multi-partition writes using a centralized Transaction Coordinator and Two-Phase Commit (2PC).

In this landmark capstone, you will implement:

  1. Atomic Transaction State Transitions: Manage transaction state across multiple topic partitions.
  2. 2PC Control Marker Injection: Append COMMIT and ABORT control records.
  3. Read-Committed Consumer Filtering: Filter out uncommitted and aborted records up to the Last Stable Offset (LSO).
