@peter-toth Hi, we are very much expecting a recursive sql. We hope you will be able to complete this pull request :)

Just update delta library

@imback82 Any progress on the doc or implementing solution in delta project? Databricks 13.2 has already implemented the liquid clustering, but we still have lack of information about this solution

Will be in future an option to change the column type of a table from int to string without overwriting the entire table? Unless such an option is now available...
