Hi,
Very new to the Triggers and Sprocs.
I have few tables which stores raw data on minute basis. I want to aggregate this data into another table to store every hour worth of data. And from there on - from this hourly Aggregated table, want to store into another Aggregate Table for a day's worth of data.
You got the direction I am going with this.. :-).... Hourly, Daily, Weekly aggregated data into their respective tables.
I could write some Java code to run periodically on these tables to transform them into Aggregate tables but that would have the overhead (Network, Disk I/O). I am wondering if there is any easy way to be able to write something at the Postgres level, where some Trigger will call some Stored Procedure on a particular table which will do the Aggregate (min, max, avg) and store that into a new table.
Any pointers or suggestions or examples would be highly appreciated !
Thanks!
Arvind
