Facebook's branch of the Oracle MySQL v5.6 database. This includes MyRocks.
use union to merge cf_id and index_id to uint64 full_id, because uint64 compare is faster than two uint32 compare
Use emplace instead of find + emplace, check pair.second for emplace success
branch `fb-mysql-8.0.23` insert should be faster when --disable-log-bin is specified, but it is slow when --disable-log-bin is specified. we found this issue when running sysbench: ```bash sysbench --db-driver=mysql --threads=80 --report-interval=1\...
