Even a window create= s a chunk on the unbounded PCollection, but the "sub" PCollection is still = unbounded. > It would be helpful for users to have a Window function that create a bou= nded PCollection (on the window) from an unbounded PCollection coming from = the source. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
