INSERT DELAYED is on its way _out _in_the_dark anyway.  I blogged this http://blog.webyog.com/2012/08/01/insert-delayed-is-gone/ 2 years ago. I am not able to really to recall full details from my brain-dead mind, but I think all references to INSERT DELAYED are now uninteresting.

when using aria as backstorage, aria engine don't support insert delayed, this will make some problems not?

about query cache i didn't found a register_query_cache_table function like aria/innodb/myisam engines, maybe we should change documentation to 'query cache isn't supported with oqgraph' instead of 'needs to be disabled'

i'm thinking about how it work with backend data store

for example...

select somefiled from oq_graph where something..

oq_graph will send some queries to data table (i don't know if it use sql or internal handler)

data table will return

oq_graph will process and send back data to client, here it can/can't query cache

if data table change, oq_graph don't know and old query cache will become inconsistent, the point is, why not it need to be disabled? should be nice a explain about it, i don't know too how it works :/

any other idea?

Hi guys, i was reading docs, and found this:

  * The query cache needs to be disabled in order to use OQGRAPH
    <https://mariadb.com/kb/en/oqgraph/> and, in older versions,
    Galera <https://mariadb.com/kb/en/galera/>.

Why query cache needs to be disabled with OQGRAPH?

My guess is that because it can't cooperate with QC and behaviour to not match our 2 defaukt patterns (like myisam or transactional). If it fit in  one of the patterns it could be switched on.
