There was a problem hiding this comment.
Previous condition was implicit, led to wrong output when the compressed data is larger.

Some recently merged PRs (#11018 + #11036) do not include enough header which may cause compile error in some systems (in particular, CUDA 11.7 + gcc-11.2). This PR adds the missing header (`<optional>`) to fix the compile issue.

Closes #11023
Expands the nvcomp adapter to cover compression. Supports SNAPPY and ZLIB.
Moves the ORC writer nvcomp compression from
stripe_enc.cuto the adapter and add ZLIB support.Adds padding to compressed blocks in writer to ensure alignment of output pointer alignment that is required for nvcomp ZLIB compression.
Minor changes:
batched_argsso it also makes sense for compression.
