Supabase is like the open-source cousin of Google's Firebase. It packs a punch with tools for building modern web apps—think real-time databases, authentication, auto-generated APIs, storage, and more.

When it comes to managing transactions, Supabase leans on PostgreSQL. Now, PostgreSQL is great with ACID properties (Atomicity, Consistency, Isolation, Durability), but only within a single database. So, if you're dealing with distributed transactions in Supabase, you'll need to be a bit more strategic.

Here are some steps to make distributed transactions in Supabase less of a headache:

Start by creating an independent transaction in each system where you need to perform operations. Treat these transactions like they're each their own little world, without worrying about the distributed nature of your setup.

Next, add some business logic to your app to coordinate these independent transactions. Think of it as a single source of truth that checks and validates each transaction before moving on to the next step.

Handle the success or failure of each transaction individually. This is super important to make sure all operations either complete or none do. Depending on your needs, you might need to include retry mechanisms in your logic.

Once all operations in all transactions are done without errors, commit all transactions. If any operation fails, roll back all transactions. You can do this using PostgreSQL's "ROLLBACK" command.

Supabase, by leveraging PostgreSQL, gives you control over transactions using Savepoints. If something goes wrong, Savepoints let you roll back to a specific point without scrapping the whole transaction.

Keep testing and monitoring your transactions, especially when working with distributed transactions in Supabase.

Remember, while Supabase is packed with powerful tools, handling distributed transactions can be tricky and might need extra steps and considerations. Plan ahead and make sure each transaction is handled properly for a more robust and reliable system.
