Request With Failover

Attempts to retrieve data from multiple sources with timeout-based failover logic.

Behavior:

  • Launches a request to each address with a 500ms timeout.
  • If a request errors, the next address is tried immediately.
  • If a request hangs, the next one is attempted in parallel after 500ms, but the previous request is still allowed to complete.
  • Returns the first successful result from any address.
  • If all attempts fail, returns ErrRequestsFailed
