TiDB is an hybrid transactional and analytical database. For analytical queries, I find that I often need window functions. I know that TiDB is MySQL-compatible, and that MySQL does not have window functions. But TiDB SQL can have extra features that MySQL SQL does not have, right? As such I wonder if there are plans to support window functions in the future?
Does TiDB plan to support window functions?
