### Describe the enhancement requested I would like to do a `join_asof` that would exclude exact matches. This is supported in pandas https://pandas.pydata.org/docs/reference/api/pandas.merge_asof.html In the example below, I expect [1,2,2,3] instead of [1,2,3,4]. ``` left = pa.table({"left": [10, 20, 30, 40], "key": [1, 1, 1, 1]}) right = pa.table( { "right": [9, 12, 30, 41], "key": [1, 1, 1, 1], "value": [1, 2, 3, 4], } ) assert left.join_asof( right, on="left", by="key", tolerance=-10, right_on="right", right_by="key" ) == pa.table( { "left": [10, 20, 30, 40], "key": [1, 1, 1, 1], "value_right": [1, 2, 3, 3], # Should be [1,2,2,3] } ) ``` ### Component(s) Python -- This is an automated message from the Apache Git Service.
