I think we should first agree on the high-level direction and then start polishing the implementation. We could ignore the implementation details and test coverage for now. I think the two most important questions are: - What are the precise semantics of an ASOF join? I suspect that different systems, such as DuckDB and Snowflake, may differ slightly, so we should first define the semantics rigorously. - What is the high-level algorithm used by the ASOF join operator? -- This is an automated message from the Apache Git Service.
