Date Tue, 21 Aug 2018 09:31:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-9311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16587208#comment-16587208

ASF GitHub Bot commented on FLINK-9311:

Xeli opened a new pull request #6594: [FLINK-9311] [pubsub] Added PubSub source connector
with support for checkpointing (ATLEAST_ONCE)
URL: https://github.com/apache/flink/pull/6594
   **What is the purpose of the change**
   Adding a PubSub connector with support for Checkpointing
   **Verifying this change**
   This change added tests and can be verified as follows:
   - Added unit tests.
   - Added integration tests to flink-end-to-end which runs against docker.
   - An example has been added in flink-examples which runs against the actual Google PubSub
service. this has been manually verified.
   - Is there a need for integration tests?
   We feel like there is and have added them. 
   **Does this pull request potentially affect one of the following parts:**
   - Dependencies (does it add or upgrade a dependency): Yes, Google Cloud Sdk for PubSub
 but because it is a connector this does not add any dependencies in flink itself.
   - The public API, i.e., is any changed class annotated with @Public(Evolving): No
   - The serializers: No
   - The runtime per-record code paths (performance sensitive): Nothing has been changed only
a connector has been added.
   - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing,

   - Yarn/Mesos, ZooKeeper: No
   - The S3 file system connector: No
   Does this pull request introduce a new feature? Yes
   If yes, how is the feature documented? JavaDocs, added an example in flink-examples and
we updated the website docs.

> I would like start adding some google cloud connectors starting with a PubSub Source.
I have a basic implementation ready but I want it to be able to:
>  * easily scale up (should I have it extend RichParallelSourceFunction for this?)
>  * Make it easier to provide the google cloud credentials. This would require being able
to send some json string / ServiceAccount to the nodes when starting up this source.
> CouldĀ this be something that would be useful for others and added to the flink connectors
