Method engine_cache_data

sql/log.cc:607–613

The cache_data to use when binlogging into the --binlog-storage-engine. With binlog in storage engine, we're optimizing for transactional event groups, and for simplicity we only pass a single cache into the engine binlog implementation. When mixing transactional and non-transactional updates in a single event group, we flush everything as out-of-band-data, and use the transa

    the engine.
