We have configured custom scaling instances in azure. I have added the recommended configuration in appsettings as in https://docs.umbraco.com/umbraco-cms/fundamentals/setup/server-setup/azure-web-apps#recommended-configuration. In Umbraco 13 documentation, https://docs.umbraco.com/umbraco-cms/fundamentals/setup/server-setup/load-balancing/azure-web-apps#lucene-examine-configuration , the recommendation is to set TempFileSystemDirectoryFactory. to LuceneDirectoryFactory for the multi-instance Scalable Public Web App. Is this true for Umbraco 10 We face corrupted index issues at times. I delete the index folders and restart the application from azure as a manual fix. What is the recommended configuration for hosting umbraco 10 application to Azure which is configured with auto-scaling. Sorry, I couldnt edit the title. Application is in Umbraco version 10.8.3
