Hi all, Few weeks back we found that event-based aggregates take a long time and that affects the performance very badly. To give you a rough idea, it takes...
Then to control each fired periodic event, there should be a separate table like guard, right? Also is it possible to "create" or "insert" a table like "delete...
Awesome! I will look over the HOWTO soon, and we'll get it into the wiki. In terms of stopping a periodic, the way I can think of to do it is to set up a...
Thank you for the guide. I wrote a HOWTO to write built-in functions and attached. I have another question though. Is it possible to stop a periodic event in a...
Folks: With the end of the semester and people going off in various directions for summer, let's call off official group meetings. We can regroup in fall if...
The following program should exhibit the behavior you expect. The boundary of a fixpoint is not reached until all internal events have been processed. Only...
In the current version of the system it's unpleasantly hard to add these. I'm not sure anybody has written down how to do it, but it's all handled in the...
Hi, I am a student in CS at Boston University. First of all, I think P2 is a very nice and interesting work. I started playing with it and I have a question....
Folks, Joe or I may have mentioned the Mono language from MIT for programming tiny little robots. Jonathan Bachrach is giving a talk on Proto (presumably the...
We're due to discuss the rewriting of the underbelly of Evita Raced in other languages, and implications on the short- and long-term fate of the current P2...
That makes sense. The only thing I'm skeptical about is whether we'd be able to build a "distributed datalog" on top of just local datalog and an imperative...
... Actually, I didn't think about including an interface that lets imperative programs register new rules directly (I guess you could insert tuples into the...

Hi Rusty, Thanks for taking a stab at this. We've all been talking about doing this, but nobody has cracked the eggs before. I find nice and clean the idea of...
Ahhh, I (we) need to set aside some time and do a reading group... Jason, thanks for making the connection to magic templates, that's a nice one. WRT to...
"Trigger" is probably not a good word to use; since SQL triggers typically can fail, and are written to muck with table state or enforce constraints. The...

I'll put up what we discussed w.r.t. semantics tomorrow. Tyson...
Just FYI, database triggers = bad, at least in the minds of most. The commercial implementations have trouble scaling, and the semantics are typically...
I've written up an event handling API for the next iteration of P2. We were discussing a few different approaches to this during today's meeting. My hope is...
