Emqx: Where messages store?

[mikybone]

Hi
I produce 200k messages, all sent successfully, some clients subscribe then offline them next begin send messages and when finished offlines became online and get all messages, so all messages exists in Ram, I check with observer ets and mnesia but not exist 200k objects in these.

where messages store?

[huangdan]

publish retained message and configure the expiration in etc/emqttd.conf
BTW we will release 'EmqPlus' product this month to help users store MQTT messages into DB

@huangdan when constructing DB persistence plugin I think that this should be taken into account: https://github.com/erlio/vernemq/issues/197

@huangdan
thanks for your replay.
I think that you didn't grasp my notice.
i don't intent to change retained message config. default config is good.
i say all not delivered messages exists in Memory, but i enter observer:start() nether ets nor mnesia didn't have 200k objects in theirs lists.

where is 200k messages putted(there is)?
