Hi. I also have a similar issue. I’ve created a dataset and one columns I customize the records to represents a list os values (ex.: [“value1”, “value2”, “value3”]), however the datatype created by Dremio is VARCHAR but I would like that column would be a LIST to make me able to use the function “FLATTEN”.
I’ve tried many ways to solve this issue with no success. Are there some way to cast a VARCHAR column to LIST or another methods to make that?
