Doing Multiple Things Safely: Using RPC for Transactions

How do you ensure data stays correct when one user action triggers multiple steps, like placing an order and updating stock? We ran into issues where partial failures left the system in an inconsistent state.

This talk covers how we solved this by moving critical logic to the server using RPC and transactions.

We’ll share:

• Why handling multi-step operations on the client can fail

• Using RPC to combine multiple actions into a single safe operation

• Ensuring consistency with transactions (all succeed or none do)

• Handling errors and edge cases in real-world scenarios

• When to use RPC vs regular API calls

By the end, you’ll understand how to design safer backend operations and avoid inconsistent data in your applications.
