Summary

Paul Stovell discusses the challenges and solutions regarding eventual consistency in software systems, particularly in the context of using RavenDB for Octopus Deploy. Initially, Octopus 1.0 attempted to force non-stale results, which had its drawbacks. For Octopus 2.0, Stovell embraced eventual consistency by implementing strategies such as providing a flag in the REST API to handle stale query results. However, he was not fully satisfied with these methods until discovering a suggestion by Chris Marisic, which he terms "perceptual consistency." This approach ensures that write operations wait for non-stale results, while read operations do not, providing a seamless user experience by the time the user is redirected. This method allows the UI to present data that appears consistent to users, effectively balancing the need for up-to-date information with system efficiency.
