   > Looks good. Minor comment. My preference is to add method in Schema class 
to get all the fieldspecs to extract. This would allow us to hide the 
incomingFieldSpec concept and also handle derived fields in future.

   One reason NOT to do this in schema is because we will be creating a new 
collection that includes all fieldspecs except timefieldspec (which will be 
changed to be the incoming granularity spec). In the past, we have been careful 
about performance and garbage generation while ingesting records from high 
throughput streams (1k+ records per second per partition, peak at 10k  when we 
are starting off consuming a new segment since we don't consume during segment 
build).
   
   I suggest we leave it as it is.
