mck commented on CASSANDRA-7688:
--------------------------------
{quote}It would be an on-demand calculation that would be moderately expensive. {quote}
[~iamaleksey] If the implementation is but a rewrite, i'm also keen on [~mbyrd] question.
{quote} Can you please elaborate on what the idea is behind storing this info in a system table?{quote}

> Currently you can't implement something similar to describe_splits_ex purely from the a native protocol driver. 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.
