Hello @mhaseeb123, after some investigation with @vuule and @etseidl, we think that a good option here could be changing the libcudf and cuDF-python default dictionary_policy
to ADAPTIVE
. Would you please create a draft PR to change the default? I would like to request evaluation by Spark in the next week or two (FYI @revans2 and @nvdbaranec)
from cudf.
That was fast!
Should we adjust the behavior of ADAPTIVE to be less restrictive?
One proposal that came out of discussion with Ed is to match compression block limit if it exists (if not, behavior is the same as ALWAYS) and follow user-specified limit if it's set. Just defaulting to ADAPTIVE and keeping a hard-coded limit might lead to larger files when we give up on dictionaries even when they don't interfere with compression.
