What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

Bulk Inserts via SQLAlchemy and Flask-SQLAlchemy

Problem

I ran into an issue today where I had to perform a bulk insert into a postgres DB. I was already using SQLAlchemy and Flask-SQLAlchemy to manage the connections to the db and I didn't want to have to use things like psycopg2 directly.

Solution

Note: SQLAlchemy provides an ORM. It isn't just an ORM. That is an important thing to be kept in mind. This means that you can bypass choose to not use the ORM layer when you don't want it. The idea with an ORM is to track changes to objects and when you have a case like that is when you'd use the ORM. In a bulk upload scenario, you don't need to track changes to objects. All you care is that everything be pushed into the DB.
