[jira] [Created] (ASTERIXDB-2392) Improve Key Comparison During LSM Merge

Chen Luo created ASTERIXDB-2392:
-----------------------------------

             Summary: Improve Key Comparison During LSM Merge
                 Key: ASTERIXDB-2392
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-2392
             Project: Apache AsterixDB
          Issue Type: Improvement
            Reporter: Chen Luo
            Assignee: Chen Luo


Merging search results from multiple LSM components using the priority queue is relatively expensive. To optimize this, we can use a special comparator without type checking since all types of index keys should be the same.
