Description

since MySQL 8.0 we have a newly redesigned lock-free REDO log implementation. However, this development involved several questions about overall efficiency around MT communications and synchronization. Curiously spinning on CPU showed to be the most efficient on low load.. -- but any plans to implement "generic" MT framework for more efficient execution of any MT apps ?
