This depends on rapidsai/cudf#7127.
This change avoids manifesting cudf
TableandColumnVectorinstances after a partition via contiguous split, as these buffers are likely to be shipped off to other nodes over the network rather than used as a columnar batch input in the same process. Instantiating all of the tables and column objects for many splits can take a significant amount of time per task.This also changes the table metadata used for UCX shuffle to use the new libcudf opaque metadata generated by the
contiguous_splitandpackmethods, eliminating a lot ofColumnMetaflatbuffer classes.
