validate()
Implementation
validate() {
// check for required fields
// alas, we cannot check 'rows' because it's a primitive and you chose the non-beans generator.
// alas, we cannot check 'exec_duration_in_us' because it's a primitive and you chose the non-beans generator.
// alas, we cannot check 'total_duration_in_us' because it's a primitive and you chose the non-beans generator.
// check that fields of type enum have valid values
