### Summary

SQLAlchemy `insert` operators are lazy instantiated, which means that they may trigger exceptions not at the point of creation, but at the point of use. When placed into a worker queue, these delayed exceptions may kill worker threads.

### Steps to reproduce

Create a SQLAlchemy `insert` operator with incompatible values argument. Place in worker queue. Worker triggers `sqlalchemy.exc.CompileError` exception, and exits.

### Platform information 

Data ETL

### What is the current *bug* behavior?

ETL pipeline fails

### What is the expected *correct* behavior?

ETL pipeline doesn't fail

### Relevant logs and/or screenshots

### Possible fixes

Pre-instantiate arguments to `insert` operators before placing in queue.
