Cross linking several related issues for tracking purposes, as this issue feels like it could be the "catch-all" for various window functions:
from blazingsql.
We are in complete agreement that window functions are an important tool in SQL. At this time they are not supported but we should have the subset that is currently supported in CUDF in the next few sprints.
from blazingsql.
Window funtions support on cudf would be great for custreamz. We process micro batches and window function support helps us to run with in batches and across batches. Most common funtion would be groupby (inter & intra micro batches) & perform computations. Use cases mentioned above (#1, #2, #3) would help a lot
