Hi. I had a brief look at CASSANDRA-2103 (expiring counter columns), and I was wondering if anyone can help me with my problem.
I want to keep some page-view stats on a URL at different levels of granularity (page views per hour, page views per day, page views per year etc etc). so my thinking was to create something a counter with a key based on Year-Month-Day-Hour, and simply increment the counter as I go along. this work's well and I'm getting my metrics beautifully put into the right places. the only problem I have is that I only need the last 48-hours worth of metrics at the hour level. how do I get rid of the old counters? do I need to write a archiver that will go through each url (could be millions) and just delete them? I'm sure other people have encountered this, and was wondering how they approached it. TIA Ian
