Support InnoDB-based binary log (transactional binlog stored within InnoDB)

This session proposes an InnoDB-based transactional binary log architecture for MySQL, where binlog events are stored directly within InnoDB instead of standalone files. The approach aims to simplify durability and crash recovery, reduce commit overhead by eliminating an extra fsync and two-phase commit coordination, and provide transactionally consistent binlog state for replication and CDC ecosystems, while preserving the existing replication protocol.
