> Currently, partition filtering only handles the first partition key and the
> type for this partition key must be string. In order to break this
> limitation, several improvements are required:
> 1. Change serialization format for partition key. Currently partition keys
> are serialized into delimited string, which sorted on string order not with
> regard to the actual type of the partition key. We use BinarySortableSerDe
> for this purpose.
> 2. For filter condition not on the initial partition keys, push it into HBase
> RowFilter. RowFilter will deserialize the partition key and evaluate the
> filter condition.
