Vikram Dixit K created HIVE-8453: ------------------------------------ Summary: Fix possible unnecessary deserialization in hive-tez Key: HIVE-8453 URL: https://issues.apache.org/jira/browse/HIVE-8453 Project: Hive Issue Type: Bug Components: Tez Affects Versions: 0.14.0 Reporter: Vikram Dixit K Assignee: Vikram Dixit K
HIVE-8409 requires deserialization of the entire row to merge on the sorted columns which is expensive. We could potentially deserialize only the sorted column from the serialized data and save on this cost. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
