Description: Why this PR? Support startup retry and timeout. Handle error in a more managed way Added boot loop protection ref The retry/backoff behavior is the same as .NET provider. Retriable error in .NET provider: ref reference: #488 Usage const config = await load(connectionString, { startupOptions: { timeoutInMs: 30_000 } }); By default the startup timeout will be 100 seconds. The pseudo code of the whole startup retry + failover logic: function startupWithRetry(): while not timeout: try: result = loadWithFailover() return result // Load successful; exit the retry loop except error: if isRetriable(error): backoffDuration = calculateBackoffDuration() sleep(backoffDuration) // Wait for the backoff duration before retrying else: throw error // Non-retriable error; rethrow immediately function loadWithFailover(): // Retrieve the fallback client list via DNS SRV records fallbackClients = getFallbackClientsFromDNS() // Attempt to perform the load operation using each fallback client sequentially for client in fallbackClients: try: result = client.load() return result // Load successful; return result immediately except error: if not isFailoverable(error): // If the error is not failoverable, immediately rethrow the error throw error // If the error is failoverable, continue with the next client // If all fallback clients have failed, throw a retriable error to trigger another retry throw new Error("All fallback clients failed")
