I noticed that running the
wcnfbasefeature extractor took a long time even after the features had already been extracted for all instances. Turns out writing the features one by one into the database is really inefficient.With this PR the
set_valuesmethods ofDatabaseandSchemanow take dicts of multiple values and write as much as possible in one SQL query. I'm not sure I fully understand the schema for non-unique features, so I tried to not modify the logic there.This made a
wcnfbasefeature extraction run for me go from ~20 minutes to 40 seconds.
