buildIndexClusteringPrefix(java.nio.ByteBuffer partitionKey,
ClusteringPrefix prefix,
CellPath path)
Used to construct an the clustering for an entry in the index table based on values from the base data.

IndexEntry |
decodeEntry(DecoratedKey indexedValue,
Row indexEntry)
Used at search time to convert a row in the index table into a simple struct containing the values required
to retrieve the corresponding row from the base table.
