I want to write a trigger which runs semi-complicated code after each insert. I have done some reading and from what I can gather this could cause problems because after insert triggers "don't spill to the disk" and can cause queue problems. Many people suggest LISTEN NOTIFY but that's not going to help me because my daemons could be offline and I would lose records.
I have two questions.
There are some hints out there that it could be possible to do asynchronous triggers based on dblink but I haven't seen any documentation or examples of this. Is there a writeup someplace about this?
Secondly I had the idea of "partitioning" the trigger processing by partitioning the table and then putting a trigger on each child table. This way theoretically I could be running the triggers in parallel. Is my presumption correct here? If I only have one table the trigger calls get queued up one at a time but if I partition my table into N tables I am running N triggers simultaneously?
