Work Description: sv2000 opened a new pull request #3102:
URL: https://github.com/apache/incubator-gobblin/pull/3102
Dear Gobblin maintainers,
Please accept this PR. I understand that it will not be reviewed until I
have checked off all the steps below!
### JIRA
- [x] My PR addresses the following [Gobblin
JIRA](https://issues.apache.org/jira/browse/GOBBLIN/) issues and references
them in the PR title. For example, "[GOBBLIN-XXX] My Gobblin PR"
- https://issues.apache.org/jira/browse/GOBBLIN-1259
### Description
- [x] Here are some details about my PR, including screenshots (if
applicable):
This PR provides an implementation of Kafka Extractor that uses Gobblin's
streaming mode. The streaming extractor is implemented to periodically
generate Flush control messages to allow the pipeline to commit the data to the
destination system. For the case of Kafka-> HDFS, the Flush message serves as
the logical point to commit files to the destination publish directory, and
checkpointing watermarks to the state store. The extractor also tracks various
statistics concerning the input source such as the (moving) average of
production rate and record sizes, which will be used by the KafkaSource when
computing work units.
### Tests
- [x] My PR adds the following unit tests __OR__ does not need testing for
this extremely good reason:
Added unit tests.
### Commits
