-You can read side input pcollection periodically into distinct windows.
-Later, when you apply side input to your main input, windows will be matched
automatically 1:1.

Review comment:
It's probably best to replace "To do this" with "To do ABC" - it'll help the
reader figure out what "this" refers to. Otherwise, if the reader is just
skimming the page and starts at this paragraph, they have to read the previous
paragraph to figure out what the pronoun refers to.
