slim bouguerra created HIVE-20932: ------------------------------------- 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
