I am making a Messenger bot and I am using Ring as my http framework.
Sometime I want to apply delays between messages sent by the bot. My expectation would be that it is safe to use Thread/sleep because this will make the active thread sleep and not the entire server. Is that so, or should I resort to clojure/core.async?
This is the code I would be writing without async:
(match [reply]
; The bot wants to send a message (text, images, videos etc.) after n milliseconds
[{:message message :delay delay}]
(do
(Thread/sleep interval delay)
(facebook/send-message sender-id message))
; More code would follow...
A link to Ring code where its behaviour in this sense is clear would be appreciated, as well as any other with explanation on the matter.
