With 1.2.7 you can use -Dcassandra.unsafesystem. That will speed up cf
creation. So you will get in even more trouble even faster!

Low number of hundreds is highest practical. The limit in practice is
amount of heap, each CF consumes heap.

Hi all:
i have two questions to ask:
1,how many column families can be created in a cluster?is there a limit to the
number of it?
2,it spents 2-5 seconds to create a new cf while the cluster contains about
1 cfs(if the cluster is empty,it spents about 0.5s).is it normal?how to
improve the ef
