No new options, no new commands… Just faster at full load, where it counts!

Starting on MySQL 8.0.1, a very updated replica server will be more efficient (and probably faster) than previous MySQL versions because of improvements in the relationship between the replication threads. Preliminary testing showed a benefit of up to 65% on Sysbench Update Index.…

Improving the Parallel Applier with Writeset-based Dependency Tracking

MySQL 8.0.1 introduces a new mechanism to track the dependencies between transactions. This feature is used to optimize the binary log applier on asynchronous replication slaves, improving the throughput significantly on workloads where there is low-concurrency on the master and/or on systems with very fast storage.…

TokuDB Hotbackup and Replication

TokuDB Hotbackup is a solution that allows you to do backups on the fly. It works as a library that intercepts certain system calls that duplicate data written to already copied parts of files, so that at the end of the backup process the copied files contain the same content as the original files. There are several blog posts describing how TokuDB Hot Backup works in details:
