It is a large data set. If there are no values, I want to send the data to a writer, if there are any values, I want to go to the terminator. My issue is that the data set is large and using a tester or attributeValidator isn't work because values are getting to my writer before validation is complete.
Solved
I am trying to test an entire field to see if there are any populated values.

Try the feature holder as it will hold all the records until the last one arrives. So your null records should hit terminator before the last correct record arrives at the feature holder.

What reader format is being used. If it is a SQL enabled format, you could use the WHERE clause on the reader to determine if any features exist with a value.

It is an Esri Geodatabase that is being used for the reader
You could use something like:
"0 = (Select count(*) from table where attribute is not null)"
That would have the database check if the table contains any not null attributes.
