Re: Announcing Phoenix: A SQL layer over HBase
Thanks, everyone, and sorry to keep you waiting :-)

We're using Phoenix in lots of different use cases and product areas at
Product Metrics
Data Archival
Server Metrics and Monitoring
Trending over time-series data

I'll go into more detail on a future post at my blog:
http://phoenix-hbase.blogspot.com. Was thinking to start with the topic
of "Performance Tuning of Phoenix (i.e. what are all the knobs and
dials)", then "How to add your own built-in function". I folks have
other topics of interest drop me a line over there.
