Hey, Data Engineers 🤓 We made it! It’s the final day of our special series exploring how to migrate from to tables.

In Part 1, we looked at the reasons for migrating, including the limitations of Hive, and how Iceberg overcomes these with its feature-rich open-table format. In the second part, we prepared for migration, and in Part 3, we considered the strategies to migrate our data.

In this final part, we’re validating our data, and today, we finish with everyone’s favorite, testing!! The good news is that Iceberg makes testing cool with its Write Audit Publish (WAP) pattern 😎

Firstly, you’ll want to use the same engines and versions your users will, like Athena or Snowflake, to ensure the accuracy of your testing.

Next, to validate updates and deletes, enable WAP on your table, create a branch from any version, and perform changes like updates or deletions within that branch. This keeps the main branch untouched until you're ready to push the final commit 💪

Finally, promote the test branch to the main branch to make your changes visible. How awesome is that? 👌

Thanks for being on this journey with us, it’s been great to have your company. Let us know how you get on with your migration and reach out if you have any questions. See you again soon!
