> This patch aims at adding support for vectorize read of data from Druid to
> Hive.
> [~t3rmin4t0r] suggested that this will improve the performance of the top
> level operators that supports vectorization.
> As a first cut am just adding a wrapper around the existing Record Reader to
> read up to 1024 row at a time.
> Future work will be to avoid going via old reader and convert straight the
> Json (smile format) to Vector primitive types.
