Subject Re: using cassandra as a real time DW
Date Fri, 06 Nov 2009 23:33:19 GMT
I didn't mean reporting tools in the sense of 'management and  
monitoring tools'. Typically data warehouse platforms have integration  
with presentational report tools, visualization, etc... Things end- 
users can use to query their data. Cassandra is all DIY in this  

Ian: if it's going to end up more like a trading desk, then Cassandra  
may be precisely the tool for this real-time DW, in my experience with  
precisely that application.
