Got this error again on a single node cassandra.
Would appreciate some pointers.

Hi Eric,
Zitat von Eric Stevens :
@Jens,
will "inactive" CFs be released from C*'s memory after i.e. a few days
or when under resource pressure?
No, certain memory structures are allocated and will remain resident on
each node for as long as the table exists.
That's good to know, while not

Hi Eric,
Zitat von Eric Stevens :
Be careful with creating many dynamically created column families unless
you're cleaning up old ones to keep the total number of CF's reasonable.
Having many column families will increase memory pressure and reduce
overall performance.

Hi,
We use a four-node Cassandra-Cluster in Version 2.1.2. Our
Client-Applications creates Tables dynamically. At one point two (or
