> If a partition has a static row and is large enough to be indexed, then {{firstName}} of the first index block will be set to a static clustering. When deserializing the column index we then incorrectly deserialize the {{firstName}} as a regular, non-{{STATIC}} {{Clustering}} - a singleton array with an empty {{ByteBuffer}} to be exact. Depending on the clustering comparator, this can trip up binary search over {{IndexInfo}} list and cause an incorrect resultset to be returned.
