First, you need to tell Storm whenever you're creating a new link in the tree of tuples. Second, you need to tell Storm when you have finished processing an individual tuple. By doing both these things, Storm can detect when the tree of tuples is fully processed and can ack or fail the spout tuple appropriately.

First, you need to tell Storm whenever you're creating a new link in the tree of tuples. Second, you need to tell Storm when you have finished processing an individual tuple. By doing both these things, Storm can detect when the tree of tuples is fully processed and can ack or fail the spout tuple appropriately. Storm's API provides a concise way of doing both of these tasks. Specifying a link in the tuple tree is called _anchoring_. Anchoring is done at the same time you emit a new tuple. Let's use the following bolt as an example. This bolt splits a tuple containing a sentence into a tuple for each word:
