    Details

      Description

      trx_sys_t::rw_trx_set implemented as std::set, which does a few quite expensive operations under trx_sys_t::mutex protection. E.g. malloc/free when adding/removing elements.

      Aim of this task is to reduce trx_sys_t::mutex contention by replacing rw_trx_set with LF_HASH.
