-----------------------------
Hi,[~jark], I understand about "make the construtor arguments to be parameters
of the {{eval}} function", but I do not understand about "do some
initialization when first processing eval method". In sql-client, create a
function by "create function udf_func as 'com.flink.myudf' " ,then use the
udf_func by "select udf_func(name) from table1".Suppose I want to define a UDF
and add a prefix to the input。 Can you write a example about how to initial
the prefix in sql-client ? Thank you very much.
