Hi all,
I maintain an online property rental application. The main focus of
the UI is the search engine, which I'd now like to improve by allowing
filtering of the search results shown on some criteria, but provide a
count of the number of properties that meet that criteria.
For example, we're looking all properties, no criteria. I'd like to
show something like:
Bedrooms:
1 Bedroom (122)
2 Bedrooms (143)
3 Bedrooms (88)
Facilities
BBQ (232)
Pool (122)
...and so on. My question is simple - What's the best way to implement
this - Do I literally have to execute a count for the WHERE criteria
with the filter criteria tagged on, or is there some clever trick that
I'm not aware of? I'd rather not count in the application as I'd like
to plan for the day we have up to 100k properties (
You could try using materialized views. Your churn is probably low
enough that it would make sense to update the views every time a
property is (de)listed.
