Do we get Concurrent issues in Azure time trigger function and retry option in activity functions? RRS feed

  • Question

  • Consider the following code, where my time trigger function runs for every minute. When Orchestrator Function(i.e RunOrchestrator) is started and it calls activity function("FhaDate") which throws argument exception. since I gave retry options while calling activity function when it fails for the first time. The activity function is retried 3 times by interval of 40 seconds.

    My Doubt is, at the time of executing activity functions for 3 attempts by keeping a time gap of 40 seconds, The new time trigger function is also triggered in meanwhile(since I gave it trigger for every 60 seconds), It will give any concurrent issues?

            public async Task RunAsync(
                                         [TimerTrigger("0 */1 * * * *")]TimerInfo myTimer, 
                                         [DurableClient]IDurableOrchestrationClient starter,
                                         ExecutionContext context, ILogger log
                    _logger.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
                    string instanceId = await starter.StartNewAsync(orchestratorFunctionName: "FHATimeTriggerOrchestrator");
                    log.LogInformation($"Started Orchestrator {instanceId}");

            public async Task RunOrchestrator([OrchestrationTrigger] IDurableOrchestrationContext context, ILogger log)
                             var retryOptions = new RetryOptions(
                                       firstRetryInterval: TimeSpan.FromSeconds(40),
                                       maxNumberOfAttempts: 3);
                 List<string> a=   await 

            public async Task<List<string>> Date([ActivityTrigger] ILogger<FHATimeTrigger> log)
                    throw new ArgumentException("Server is down");

    Please tell me the correct flow, as I am new to durable functions.

    Thanks in advance
