staleSec, gapMs and crossOriginLoads are -1 when unknown; mismatch is -1 when nothing was
compared, 0 for a match and 1 for a mismatch. A page's loads report is a row with blob1 of
loads, the view id as blob2 and at and the count as double1 and double2. Analytics
Engine caps an index at 96 bytes and a row at 16 KB, so a body longer than MAX_BEACON_BLOB
bytes is written as several points, one per slice, with the same index, content type, vendor and
at; join the slices by those and double2 (the slice number) to rebuild it. Nothing is cut off.
A sink for a Workers Analytics Engine dataset, one data point per event.
