Description

1. no data for an entire stream won't trigger gap alert (use local time & batch window)
2. no data policies definition is too complex, make the nodata offer optional settings in stream definition
3. bolt parallellism will cause multiple alerts in the same time window (use loopback)

The extension of no data alert design is posted at https://cwiki.apache.org/confluence/display/EAG/Alert+Engine+Extension.
