getSchemaUpdateOptions()

public List<JobInfo.SchemaUpdateOption> getSchemaUpdateOptions()

[Experimental] Returns options allowing the schema of the destination table to be updated as a side effect of the query job. Schema update options are supported in two cases: when writeDisposition is WRITE_APPEND; when writeDisposition is WRITE_TRUNCATE and the destination table is a partition of a table, specified by partition decorators. For normal tables, WRITE_TRUNCATE will always overwrite the schema.
