Hi, I’m new to Clojure async operations (while have a good understanding of other things) and want to get a bit of advice. Atoms & agents still confuse me.
What I’m implementing is a small REST webservice with custom in-memory database. Database is indexed by unique key, basically it’s a map (I’ll denote it as MAP). There are two basic operations: *PUT /api/…/<KEY>.* Initiate an update for given KEY. The HTTP response should be returned immediately, and the processing should be done asynchronously. The processing consists of downloading a data file from web and doing some data crunching, the result should go into MAP. *GET /api/…/<KEY>.* Use (get MAP KEY) and request params to generate response synchronously. The tricky part (well, for me :) is that parallel PUT requests should be possible. The downloading and processing can and should go in parallel, independently, whereas updating the MAP should come synchronized, one-after-the-other. How would you implement this? -- Oleg. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
