[jira] [Created] (CASSANDRA-9336) Partition paging

Robert Stupp created CASSANDRA-9336:
---------------------------------------

             Summary: Partition paging
                 Key: CASSANDRA-9336
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9336
             Project: Cassandra
          Issue Type: New Feature
            Reporter: Robert Stupp
            Priority: Minor


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.)
