Key Vault performance issue breaks Azure Functions
When retrieving the Azure Functions host key, the service sometimes returns a GatewayTimeout error.
The Azure Web App support team analyzed the issue and identified a Key Vault performance issue as the root cause.
"More specific, the related KeyVault API call took longer than expected. As a result of this issue, the related function site failed to be started properly so “ListKey” threw out “Timeout” exception [...]"
Please vote for implementing "Key Vault Reference Perf Improvements".
