Field Detail

MAX_WINDOW_MS

public static final long MAX_WINDOW_MS

The maximum amount of time between the ReviewDb timestamp of the first and last events batched together into a single NoteDb update.

Used to account for the fact that different records with their own timestamps (e.g. PatchSetApproval and ChangeMessage) historically didn't necessarily use the same timestamp, and tended to call System.currentTimeMillis() independently.
