Description we can let users pass their own _retryable_error method, which will validate if retry is allowed or not. As of now, databricks operators only accept retry_limit and retry_delay. Adding support for custom retry function and af...

of the design trade-offs between applying user-defined functions on existing computation kernels vs. partially re-writing the kernel in SQL and thus taking advantage of the underlying SQL query optimizer. Our performance evaluation demonstrates almost linear scalability for the best design choice. ...
