Fields§
§subset: Option<Arc<[PlSmallStr]>>
Subset of columns that will be taken into account.
maintain_order: bool
This will maintain the order of the input.
Note that this is more expensive.
maintain_order
is not supported in the streaming
engine.
keep_strategy: UniqueKeepStrategy
Which rows to keep.
slice: Option<(i64, usize)>
Take only a slice of the result
