Hello Kudu developers! Kudu has made great efforts to improve predicate pushdown and a lot of work has been done here(KUDU-1639). And there seems to be a decent amount of interest in the support of OR/NOT predicate. To name a few that I've seen, there is: - Add NOT EQUAL predicate type (KUDU-2516) - Support NOT predicates (KUDU-2864) - Support OR predicates (KUDU-2863) - KuduScannerBuilder OR operator for predicates (KUDU-2494)
So, I and Yao Xu start a document to organize our thoughts on the design of those predicates. Please take a look, if you're interested. The feedback and discussion is opened. https://docs.google.com/document/d/1kuJKNWXv7gL7bEjSytV-7-RGfaJhru1zrxgdP3QUk3Q/edit?usp=sharing Thanks!
