Subject Re: 1000's of column families
Date Thu, 27 Sep 2012 12:14:26 GMT
Is there a non rhetorical question in there? Maybe is that a feature
request in disguise?


The question was basically, Is Cassandra ok with as many CF's as you want?
 It sounds like it is not based on the email that every CF causes a bit
more RAM to be used though.  So if cassandra is not ok with as many CF's
as you want, does anyone know what that limit would be for 16G of RAM or
something I could calculate with?

Thanks,
Dean
