Simple application demonstrating the issue raised in a GCP bug report.
Build using ./gradlew build, and then run the application using java -jar build/libs/bigtable-jdk-issue-all.jar.
At least Java 17 is required to run the example.
If the firewall is configured to refuse incoming network connections the application takes ~16-17 seconds to run, but if the firewall is configured to accept incoming network connections it only takes a couple of seconds.
Notes:
- GCloud authentication using
gcloud auth loginmust have been performed.- If no valid credentials are registered the application fails immediately with an exception.
- This has been tested on Mac OS Sonoma 14.4
- Note that system restart is required for firewall settings to be properly applied.
- The configured GCP project, instance and table are completely irrelevant:
- This simple demo uses values that are not pointing at anything real, but the result is identical with proper values.
