Work Description: ZihanLi58 opened a new pull request, #3902:
URL: https://github.com/apache/gobblin/pull/3902
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
- [ ] 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-2024
### Description
- [ ] Here are some details about my PR, including screenshots (if
applicable):
We are seeing slowness in the GobblinMCEWriter, which will cause us huge
backlog when handling large topic and affect the other topics in the same
container for GMIP. After benchmark, we identify that we can improve the
computeSpec part to reduce the duplicate work, also we can add the file size
information in GMCE to avoid calling HDFS for each file.
With this change, I verified that we can now process more than 7000
messages/minute vs 1000 messages/minute before the change.
### Tests
- [ ] My PR adds the following unit tests __OR__ does not need testing for
this extremely good reason:
tested by running both ingestion and metadata pipelines, and verify to adopt
this change, we need to apply change to metadata pipeline first.
### Commits
- [ ] My commits all reference JIRA issues in their subject lines, and I
have squashed multiple commits if they address the same issue. In addition, my
commits follow the guidelines from "[How to write a good git commit
message](http://chris.beams.io/posts/git-commit/)":
1. Subject is separated from body by a blank line
2. Subject is limited to 50 characters
3. Subject does not end with a period
4. Subject uses the imperative mood ("add", not "adding")
5. Body wraps at 72 characters
6. Body explains "what" and "why", not "how"
