Post on Trigger
I am fairly new to CouchDb and loving it so far. I think this database is shockingly underated. I love the
"Relax" approach and the design choices that have been done, and I hope things will continue with the same philosophy.
I couldn't find if this has been discussed before but I was thinking that it would be extremely cool to be able
to setup triggers that POST arbitrary json to arbitrary endpoints. I think this would be a killer feature
if there was built-in support for that - and seems to fit well with the HTTP approach of couch.
So basically, this would be about allowing us to add an arbitrary number of triggers to any view. Each
trigger would be called only if the view emitted "something" and the trigger would receive the document
passed as a parameter to the view (this is to take advantage of the update frequency of views) Then in terms
called from the triggers.
For the same purpose, it would be interesting to introduce configuration documents at the database level
whose properties could be accessed from these triggers (I'm thinking of situations when one would need to
call a different URL when in testing, staging, production etc...)
maintenance tasks. More generally, this would eliminate the need for most of the maintenance jobs out
there while making these systems much more efficient by removing the need to run jobs at arbitrary times
even when this is not necessary. Also, since most web frameworks are asynchronous and process each
request in a different thread, this would be a way to easily parallelize certain operations.
I just wanted to know if there was any chance to see this come out one day or if this would be a "no-go" for design
of philosophical reasons.
