Migrating Datastores

Friday, December 09, 2022 - 11:30 am12:00 pm AEDT

Tessa Bradbury, Buildkite


As software engineers, we're often trying to keep up with growing products and new technologies, this means we're often needing to move data from an old datastore to a new one—while the data's still in use. Unsurprisingly, this comes with some challenges.

Tessa will use a recent Redis migration at Buildkite as a case study to explore:

  • The different types of data you might be working with
  • Strategies to safely and efficiently migrate each type
  • How to test; locally, in CI, and in prod

Also, communicating the value of these types of infrastructure projects outside of engineering can often be difficult. Tessa will explain some of the team's strategies to ensure the value of this work was visible across the wider organization.
