Level-Up Your Cluster: Upgrading Elasticsearch
For some, upgrading can be the bane of their job. Does the latest version fix any bugs that affect my cluster? Will the new minor release break my system?
Often, users decide to upgrade based on a new feature they need, or a bug fix that affects them. But upgrading can have other benefits too, like improved performance and decreased index size. In this talk, we will explore why upgrading can help you, what questions to ask yourself before upgrading, and how to actually perform that pesky upgrade with minimal misery.
