leonid.fedorov Question : what is the tentative syntax to invoke UDF ? Do you now of any plans by the server or xpand team to do similar features |

Syntax is discussable. In my draft it is: select columnstore_load_data(params....) I do not know about similar features in our spare products, but if we want syntax to be simular, it's not hard to change |
