Edward Zhang commented on EAGLE-343:
------------------------------------
To alert when value changes, we can use 2 event slide length window, and check
if they are same (probably you can compare avg with min). Senthil you can
experiment that please.
Pattern match also works, but looks 2 event slide length window is more
straightforward.
Regarding advanced requirement of content check between 2 event, that is also
doable, for example we can do hash on the missing block list, but the
complexity is on the ingestion side, we have to feed missing block list.
