Summary: Vectorize Druid Storage Handler Reader
Key: HIVE-20932
URL: https://issues.apache.org/jira/browse/HIVE-20932
Project: Hive
Issue Type: Improvement
Reporter: slim bouguerra
Assignee: slim bouguerra
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.
