Roachtest: BackupFixture/tpcc/warehouses=5000/incrementals=48 Failed

by ADMIN 69 views

Introduction

CockroachDB is a distributed relational database that provides a highly available and scalable solution for modern applications. However, like any complex system, it can experience failures and issues that need to be investigated and resolved. In this article, we will discuss a recent failure of the roachtest backupFixture/tpcc/warehouses=5000/incrementals=48 test, which is a critical component of the CockroachDB testing framework.

Test Failure Details

The roachtest backupFixture/tpcc/warehouses=5000/incrementals=48 test failed on the release-25.2.0-rc branch with the commit hash 545da2936c70fdecb9bbbd652aa4bd90b8d26dad. The test timed out after 2 hours and 0 minutes, and the test artifacts and logs can be found in the /artifacts/backupFixture/tpcc/warehouses=5000/incrementals=48/cpu_arch=arm64/run_1 directory.

Test Parameters

The test was run with the following parameters:

  • arch=arm64
  • cloud=aws
  • coverageBuild=false
  • cpu=8
  • encrypted=false
  • fs=ext4
  • localSSD=false
  • metamorphicBufferedSender=false
  • runtimeAssertionsBuild=false
  • ssd=0

Investigation and Resolution

To investigate this failure, we need to analyze the test logs and artifacts to determine the root cause of the issue. The test logs can provide valuable information about the test execution, including any errors or warnings that may have occurred.

In addition to analyzing the test logs, we can also use tools like Grafana to visualize the test execution and identify any performance issues that may have contributed to the failure.

Same Failure on Other Branches

The same failure has been observed on other branches, including #145410. This suggests that the issue may be related to a broader problem with the roachtest framework or the underlying CockroachDB code.

Action Items

To resolve this issue, we need to:

  1. Analyze the test logs and artifacts to determine the root cause of the failure.
  2. Use tools like Grafana to visualize the test execution and identify any performance issues that may have contributed to the failure.
  3. Investigate the same failure on other branches to determine if it is related to a broader problem with the roachtest framework or the underlying CockroachDB code.

Conclusion

The roachtest backupFixture/tpcc/warehouses=5000/incrementals=48 test failure is a critical issue that needs to be investigated and resolved. By analyzing the test logs and artifacts, using tools like Grafana, and investigating the same failure on other branches, we can determine the root cause of the issue and take corrective action to prevent similar failures in the future.

Introduction

In our previous article, we discussed the recent failure of the roachtest backupFixture/tpcc/warehouses=5000/incrementals=48 test. In this article, we will provide a Q&A section to address some of the common questions and concerns related to this issue.

Q: What is the roachtest framework?

A: The roachtest framework is a set of tools and tests used to verify the correctness and performance of the CockroachDB database. It includes a wide range of tests, from basic unit tests to complex integration tests.

Q: What is the purpose of the backupFixture/tpcc/warehouses=5000/incrementals=48 test?

A: The backupFixture/tpcc/warehouses=5000/incrementals=48 test is a critical component of the roachtest framework. It simulates a large-scale database workload, with 5000 warehouses and 48 incrementals, to test the performance and reliability of the CockroachDB database.

Q: What caused the test failure?

A: The test failure was caused by a timeout after 2 hours and 0 minutes. The test logs and artifacts are being analyzed to determine the root cause of the issue.

Q: Is this a known issue?

A: Yes, this issue has been observed on other branches, including #145410. This suggests that the issue may be related to a broader problem with the roachtest framework or the underlying CockroachDB code.

Q: How can I help investigate this issue?

A: If you are interested in helping investigate this issue, please reach out to the CockroachDB team. We can provide you with access to the test logs and artifacts, and you can help us analyze the data to determine the root cause of the issue.

Q: What are the next steps to resolve this issue?

A: The next steps to resolve this issue are:

  1. Analyze the test logs and artifacts to determine the root cause of the failure.
  2. Use tools like Grafana to visualize the test execution and identify any performance issues that may have contributed to the failure.
  3. Investigate the same failure on other branches to determine if it is related to a broader problem with the roachtest framework or the underlying CockroachDB code.

Q: How can I stay up-to-date with the latest developments on this issue?

A: You can stay up-to-date with the latest developments on this issue by following the CockroachDB team on GitHub, and by checking the roachtest framework documentation for any updates or changes.

Q: What are the implications of this issue for CockroachDB users?

A: The implications of this issue for CockroachDB users are still being determined. However, it is possible that this issue may affect the performance and reliability of the CockroachDB database, particularly in large-scale deployments.

Conclusion

The roachtest backupFixture/tpcc/warehouses=5000/incrementals=48 test failure is a critical issue that needs to be investigated and resolved. By working together, we can determine the root cause of the issue and take corrective action to prevent similar failures in the future.
