Jason Wilder d0cc98356b Fix error calling MarshalJSON for type *influxdb.Result: json: unsupported value: NaN 
If the MapMean did not have any values in the iterator, it would return
and empty meanMapOutput().  ReduceMean would in turn divider the results
by an unitialized float64 producing a NaN.  NaN is not serializable to JSON
by default.

Paul Dix 113995032e WIP: Initial implementation of remote mapper for distributed queries. 2015-04-10 16:11:34 -07:00
Paul Dix 6c46a5c83b Add chunked responses and streaming of raw queries. 
Refactored query engine to have different processing pipeline for raw queries. This enables queries that have a large offset to not keep everything in memory. It also makes it so that queries against raw data that have a limit will only p
rocess up to that limit and then bail out.

Raw data queries will only read up to a certain point in the map phase before yielding to the engine for further processing.

Fixes #2029 and fixes #2030
