Hướng nghiên cứu

Start by reading QueryIndexEndpointStrategy and ProbeEndpointsStrategy, which are named in the issue, and trace where SBA switches between them. Identify how endpoint detection failures are handled and where retry configuration belongs. Done means configurable retries occur before fallback to probing; add or update tests for that behavior.

Hello.

I'm using the latest 4.1.4 version of SBA and I can observe the following behaviour:

Basically, if the QueryIndexEndpointStrategy fails, SBA switches automatically to ProbeEndpointsStrategy and starts to flood with requests.

While the behaviour is understandable, it would be nice to have some configurable retries in place before falling back to the ProbeEndpointsStrategy.
