GCP Cloud Run service timing out on HTTP requests after deploying new version with Spring Boot
I've looked through the documentation and I'm still confused about I'm optimizing some code but I'm sure I'm missing something obvious here, but I recently deployed a new version of my Spring Boot application to GCP Cloud Run, and I'm working with a timeout scenario..... My application processes incoming HTTP requests that involve fetching data from a Google Cloud SQL database. Since the deployment, I'm receiving a `504 Gateway Timeout` behavior for requests that take longer than 60 seconds. I've tried increasing the timeout setting in the Cloud Run service configuration to 120 seconds, but I still encounter the same scenario. Here's the relevant part of my `application.yml` configuration: ```yaml server: port: 8080 spring: datasource: url: jdbc:mysql://<CLOUD_SQL_INSTANCE_IP>:3306/mydb username: myuser password: mypassword jpa: hibernate: ddl-auto: update show-sql: true ``` I also adjusted my service in Cloud Run to allow up to 120 seconds of request timeout, but the scenario continues. I have verified that my database is reachable, and I can run longer queries successfully from my local environment. Just to diagnose the scenario, I added some logging to the controller to determine how long each request takes, and I noticed that any request processing that exceeds 60 seconds leads to the timeout behavior. Additionally, I checked the Cloud Run logs and saw entries indicating that the requests are being terminated after 60 seconds but did not provide further insights into why. Here’s a snippet of my controller that handles the request: ```java @RestController @RequestMapping("/api") public class MyController { @Autowired private MyService myService; @GetMapping("/data") public ResponseEntity<String> getData() { String result = myService.fetchData(); // This can take a while return ResponseEntity.ok(result); } } ``` I suspect it might be related to how long Cloud Run allows a request to be processed or possibly an scenario with the database connection pool timing out. Any suggestions or insights on how to troubleshoot this would be greatly appreciated. What's the best practice here? For context: I'm using Java on Linux. Thanks for your help in advance! This is happening in both development and production on Windows 10.
