The following screenshot shows an example flow that learns a Random Forest model using a local H2O context which is then registered as UDF and used to predict the classes for a database table with previously unseen data. The prediction result is then stored in a Snowflake table. For another...

Then we can create a RAP, RAP_REGION_USER, that checks to see if the input region ID is in the array returned by the UDF_REGIONS() when passing in the CURRENT_USER() . With the RAP defined, we just need to attach that RAP to the APP_DATA table on the REGION_ID column. Now ...

When a SQL statement calls your Java UDF, Snowflake calls a Java method you have written. Your Java method is called a “handler method”, or “handler” for short. As with any Java method, your method must be declared as part of a class. Your handler method can be a static method ...
