How Achaeans Would Construct Columns in Troy
... The core idea of querying Trojan Columns is to push a part of the query tree down to the UDF. This means that a part of the query is processed by the UDF while the remaining query is still processed by the standard database query executor. Let’s consider query 6 from the TPC-H benchmark [13] as a ru ...
