From what I can tell Schemaless has updates but represents them as inserts. When you want to change something (e.g. change the billing status of a trip), it writes a new billing status for the trip and consumers will always ask for the latest billing status for the trip, which is the most recent and up-to-date one.

Take this with a grain of salt, I just read the Schemaless articles yesterday.

That is how I understood it too. Updating your data with a call to insert won't run into the same problems as updating your data with a call to update. Their immutability implementation seems like it would behave nearly the same under both databases.

Isn't reddit doing schema-less on postgres?
