             Summary: Use gtest's sharding support to parallelise long-running be-tests
                 Key: IMPALA-5684
                 URL: https://issues.apache.org/jira/browse/IMPALA-5684
             Project: IMPALA
          Issue Type: Improvement
          Components: Infrastructure
    Affects Versions: Impala 2.9.0
            Reporter: Henry Robinson
            Assignee: Henry Robinson


Googletest has support for sharding test cases from a single test across different processes.
We could use this to speed up the execution of some backend tests - particularly {{expr-test}}.

The runtime of each expr-test is heavily skewed, but once we have sharding we can make the
test cases a bit more fine-grained and then automatically get better performance as the sharding
handles the work balancing.
