🔗 Batch updates and advanced inserts in Ecto for Elixir

When you build Elixir applications, you'll likely encounter scenarios where you need to handle large datasets efficiently. Whether you're importing user data from a CSV file, updating thousands of product prices, or synchronizing data from external APIs, performing operations one record at a time can quickly become a performance bottleneck.

In this two-part tutorial, we'll start by exploring Ecto's powerful batch update and advanced insert capabilities for handling bulk data operations. Then, in the second part, we'll learn how to integrate AppSignal for Elixir to build an observability layer on top of Ecto to catch errors and any performance issues that could arise.
