The data collection could be very > huge as the discard period could be relative long time. If > fireOnlyUpdatedPanes is false probably there don't have much space to > improve. But if fireOnlyUpdatedPanes is true, we don't have to go through the > whole data collection. We only need to go through the window and key which > handle after last trigger. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
