GitHub user KeeganJin closed a discussion: How do I create a UDF and enable datafusion to parse it in datafusion rust?
Hi all, I want to create a UDF in a stream processing system with the ability to call a ML operator. since I didn't find any support related to that. I wonder if anyone here could help? The table looks like this: `device_id | data` `1 | data_01` `2 | data_02` I want to perform ML operator on the "data" column, which leads me to UDF. The SQL query is like: `SELECT ML_Operator(data) FROM table`, where the ML_Operator should be the user-defined function. I wonder if it is possible in datafusion, and if possible how would the query be parsed? Thanks!
