-------------------------------------------
Summary: Cache to optimize SearchArgument deserialization
Key: HIVE-17669
URL: https://issues.apache.org/jira/browse/HIVE-17669
Project: Hive
Issue Type: Improvement
Components: ORC, Query Processor
Affects Versions: 2.2.0, 3.0.0
Reporter: Mithun Radhakrishnan
Assignee: Chris Drome
And another, from [~selinazh] and [~cdrome]. (YHIVE-927)
When a mapper needs to process multiple ORC files, it might land up having use
essentially the same {{SearchArgument}} over several files. It would be good
not to have to deserialize from string, over and over again. Caching the object
against the string-form should speed things up.
