------------------------------------------
Summary: [C++][Compute] Add Find method to Grouper
Key: ARROW-13706
URL: https://issues.apache.org/jira/browse/ARROW-13706
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Michal Nowakiewicz
Fix For: 6.0.0
After SwissTable implements find() method in ARROW-13532, Grouper can add
Find() method to its interface. Note that the main problem is that Grouper uses
mutable member variables for storing temporary data, whenever it is doing hash
table lookups, even when the hash table is used as read-only. Grouper is also
not thread-safe, while Find() method ideally should be thread-safe, working on
immutable object.
