Aleksey Yeschenko commented on CASSANDRA-7688:
----------------------------------------------
There most definitely won't be a separate CQL command just for that, but when
we switch this to a virtual table implementation (when we have those) it might
be as simple as {{UPDATE}}ing a boolean field in that table to trigger recalc.
We could temporarily add a JMX method. Or you could set the interval to be
really low for now, and add some sleep.
I know it's a bit ugly, but it's just an interim measure.

> Currently you can't implement something similar to describe_splits_ex purely

> https://datastax-oss.atlassian.net/browse/JAVA-312 is open to expose easily
> getting ownership information to a client in the java-driver. But you still
> need the data sizing part to get splits of a given size. We should add the
> sizing information to a system table so that native clients can get to it.
