@Documented @Retention(value=RUNTIME) @Target(value=TYPE) @Experimental(value=SPLITTABLE_DO_FN) public static @interface DoFn.UnboundedPerElement
DoFn
specifying that the DoFn
performs an unbounded amount of work per input element, so
applying it to a bounded PCollection
will produce an unbounded PCollection
. It
is an error to specify this on a non-splittable DoFn
.
