If we accept the PR, a [maintainer](MAINTAINERS.md) will merge your change and usually take care of backporting it to appropriate branches ourselves.

If we reject the PR, we will close the pull request with a comment explaining why. This decision isn't always final: if you feel we have misunderstood your intended change or otherwise think that we should reconsider then please continue the conversation with a comment on the PR and we'll do our best to address any further points you raise.

## Troubleshooting Failing Builds

The OpenSearch testing framework offers many capabilities but exhibits significant complexity (it does lot of randomization internally to cover as many edge cases and variations as possible). Unfortunately, this posses a challenge by making it harder to discover important issues/bugs in straightforward way and may lead to so called flaky tests - the tests which flip randomly from success to failure without any code changes.

If your pull request reports a failing test(s) on one of the checks, please:
- look if there is an existing [issue](https://github.com/opensearch-project/OpenSearch/issues) reported for the test in question
- if not, please make sure this is not caused by your changes, run the failing test(s) locally for some time
- if you are sure the failure is not related, please open a new [bug](https://github.com/opensearch-project/OpenSearch/issues/new?assignees=&labels=bug%2C+untriaged&projects=&template=bug_template.md&title=%5BBUG%5D) with `flaky-test` label
- add a comment referencing the issue(s) or bug report(s) to your pull request explaining the failing build(s)
- as a bonus point, try to contribute by fixing the flaky test(s)
