distributedIterator
Returns element iterator that can be shared across multiple applications. Creating multiple iterators on the same object with this method will result in a single shared iterator. See distributedIterator(String, String, int) for creating different iterators.- Parameters:

- shared elements iterator
-
distributedIterator
Returns iterator over elements that match specified pattern. Iterator can be shared across multiple applications. Creating multiple iterators on the same object with this method will result in a single shared iterator. See distributedIterator(String, String, int) for creating different iterators.- Parameters:
pattern
- element pattern- Returns:
- shared elements iterator
-
distributedIterator

- element patterncount
- batch size- Returns:
- shared elements iterator
-
