Add in support for NULL_LOGICAL_AND and NULL_LOGICAL_OR binops (#10016)
Browse files Browse the repository at this point in the history
These already exist as a part of the AST. Spark's AND/OR implementations follow these requirements and to be able to re-implement it using existing CUDF functionality ended up being very expensive. We found that this one change could cut almost 13% off the total run time on TPC-DS query 28.  AND/OR are common enough in all queries we expect this to have a major performance impact generally.

We tried to use the AST version instead, but depending on the hardware used the overhead of AST does not pay for itself when the input/intermediate outputs are boolean columns. It appears to be because the amount of memory transfers saved is relatively small in most boolean cases and on large GPUs like the a100 the intermediate results might even fit entirely in the L2 cache.
