                  I would like to see maxscale using EITS embedded MariaDB tables to produce QP. as maxsale can link to multiple backends one need to select witch backend statistics tables to use. Also we can use same concept to enable non blocking analyze table that populate a new version of statistics content and make the switch to the new version atomic despite i agree that this is may be not needed as a per record modification may not affect quality of EITS plans
