Transaction level only has effect on transactional engines

yeap :) i tested with non transactional just to confirm the "dumb doubt"

(and note that read uncommited is treated as read commited on TokuDB if i recall correctly)

hummmm maybe i read this from tokudb... i think you are right, thanks!

thus the variable has no effect on MyISAM and Aria.

yeap... but aria have a jornal file... maybe we could do something...

i was searching jira and found a delete/update concurrent with aria (MDEV-23), maybe that's the 'solution'

anyone know about this MDEV?

hi guys, i use read uncommited sometimes with innodb, that's nice and work
but now, i'm using a myisam table, and a aria table....
does read uncommited work with this kind of engine? i tested and table stay 'waiting table lock' while a looooong update occurs
i don't know what's the internal diference but is possible to "easily" implement read uncommited to myisam/aria?
