ASF GitHub Bot commented on BEAM-2899: -------------------------------------- tgroh opened a new pull request #4197: [BEAM-2899] Port DataBufferingOutboundObserver URL: https://github.com/apache/beam/pull/4197 Move to sdks/java/fn-execution. The outbound observers are generally the same on both ends. Introduce a CloseableFnDataReceiver, and remove 'Closeable' from the default FnDataReceiver. Follow this checklist to help us incorporate your contribution quickly and easily: - [ ] Make sure there is a [JIRA issue](https://issues.apache.org/jira/projects/BEAM/issues/) filed for the change (usually before you start working on it). Trivial changes like typos do not require a JIRA issue. Your pull request should address just this issue, without pulling in other changes. - [ ] Each commit in the pull request should have a meaningful subject line and body. - [ ] Format the pull request title like `[BEAM-XXX] Fixes bug in ApproximateQuantiles`, where you replace `BEAM-XXX` with the appropriate JIRA issue. - [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why. - [ ] Run `mvn clean verify` to make sure basic checks pass. A more thorough check will be performed on your pull request automatically. - [ ] If this contribution is large, please file an Apache [Individual Contributor License Agreement](https://www.apache.org/licenses/icla.pdf). --- ---------------------------------------------------------------- This is an automated message from the Apache Git Service.

It would serve multiple purposes: > (1) A reference implementation for other runners. Ideally, any new feature > should be implemented in the ULR first. > (2) A fully-featured test runner for SDKs who participate in the > portability framework. It thus complements the direct runners. > (3) A test runner for user code that depends on or customizes the runtime > environment. For example, a DoFn that shells out has a dependency that may be > satisfied on the user's desktop (and thus works fine on the direct runner), > but perhaps not by the container harness image. The ULR allows for an easy > way to find out. > The Java direct runner presumably has lots of pieces that can be reused. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
