説明
Enhancement
There are some expressions that has been implemented in TiKV copr but the push down is not enabled. There are two reasons:
- The test is insufficient.
- The implementation is not compatible with MySQL because the underlying library is different(such as the math library).
For the first situation, we can add more testcase to ensure its correctness. Especially when Projection push down is finished, We can do testing with greater efficiency.
