      Description

      Currently, index_interval is measured in number of keys: how may keys before adding an entry to the index summary. After CASSANDRA-2319, each index entry also contains the columns index for the row, so index entry can be a bit bigger and of differing sizes. Measuring in number of keys is thus sub-optimal and difficult to tune, since you might want a different setting depending of whether your rows are big or small, but the setting is global.

      So we should move to measuring the interval in bytes.
