how to implement aggregated tables in vertica

Question

how to implement aggregated table in vertica database? does vertica provide any inbuilt options. If it is not possible, what is the alternative ? I basically want to avoid the overhead of updating in both fact table and aggregated table.

Answer 1

For an aggregated table, I have rolled my own in the past. Using some sort of script running via cron and keeping track of what was previously aggregated.

I would also highly recommend setting up projection(s) specifically tuned for the types aggregate query you desire. If done properly, you can see some pretty good results.
