---------------------------------
Summary: Extend physical operator test framework to test mini
plans consisting of multiple operators
Key: DRILL-5459
URL: https://issues.apache.org/jira/browse/DRILL-5459
Project: Apache Drill
Issue Type: Improvement
Components: Tools, Build & Test
Reporter: Jinfeng Ni
DRILL-4437 introduced a unit test framework to test a non-scan physical
operator. A JSON reader is implicitly used to specify the inputs to the
physical operator under test.
There are needs to extend such unit test framework for two scenarios.
1. We need a way to test scan operator with different record readers. Drill
supports a variety of data source, and it's important to make sure every record
reader work properly according to the protocol defined.
2. We need a way to test a so-called mini-plan (aka plan fragment) consisting
of multiple non-scan operators.
For the 2nd need, an alternative is to leverage SQL statement and query
planner. However, such approach has a direct dependency on query planner; 1)
any planner change may impact the testcase and lead to a different plan, 2)
it's not always easy job to force the planner to get a desired plan fragment
for testing.
In particular, it would be good to have a relatively easy way to specify a
mini-plan with a couple of targeted physical operators.
This JIRA is created to track the work to extend the unit test framework in
DRILL-4437.
