in reply to Re^5: DBI - Table names & placeholders
in thread DBI - Table names & placeholders

Well, it just irks me that I have to do a separate prepare and execute for every single row of data that I want to insert - as opposed to "prepare once, execute many times".

But, it's no biggie - the job is done and the data is flowing.

    You're describing my second snippet.
      oh, duh - yes, of course!

      I've modified my code to use the caching technique in that example, and it works a treat. In production this will be generating ~100,000 inserts on each run (every 2 hours), so I expect it may provide quite a performance boost.

      Thanks again :)

[ambrus]: Corion: ah, so you want a library that parses HTTP, and you want to do the IO yourself, and don't want a full AnyEvent wrapper.
[ambrus]: Corion: I think I parsed a HTTP header from a string with LWP once. You can definitely use that to create a HTTP message too. The problme is
[ambrus]: that if you do that, you'd have to find where each HTTP response ends, which is nontrivial if you want persistent connections (essential for performance if you have small requests).
[Corion]: ambrus: Yes, ideally an API that I feed the incoming data piece by piece and that I can ask "is that response done" and "what should I do next" and "please construct the appropriate redirect for me"
[Corion]: ambrus: Yes, ideally the module would do all that nasty stuff for me and give me a way to ask it what the current situation is
[ambrus]: Corion: you could also consider using some wrapper over the multi interface of curl, I think Net::Curl might be a good one, since implementing enough of what it expects from the event loop might be easier than a full AnyEvent interface.
[ambrus]: Corion: you could also consider using IO::Async and its POE driver and some HTTP module for it, but I don't know if that would solve your problems with AnyEvent+POE
[ambrus]: Corion: wait, you didn't say POE. You said Prima, let me look up what that is.
[ambrus]: Corion: have you considered just writing an AnyEvent integration for that thing?
