What is a 'context deadline' and how is it configured?

The 'context deadline' is the maximum time a client application will wait for a server response during the server selection process. It's configured within the application's settings, often as a timeout value in milliseconds. The specific configuration location depends on the application framework (e.g., Spring Boot, Node.js). Increasing the deadline can resolve the error if servers are slow to respond, but it might mask underlying performance problems. It's best to find and address the root cause of the slowness.
