> A common problem in data modeling is how to prevent too-big partitions. For example, a table usually has 100 rows per partition, but outliers have millions of rows per partition. One "generic" way could be to split the outliers into separate buckets - but reading these outliers may involve multiple read requests (which is bad).
> CASSANDRA-9231 could provide some base functionality - i.e. allow users to "bind" different partitions to the same nodes.
> Making it possible to select all or a range of partitions per routing-key could help - ideally with sorting. (Comparable to what a clustering key is for a partition.)
