Community-led development "The Apache Way"
This was extracted (@ 2022-09-21 16:10) from a list of minutes
which have been approved by the Board.
Please Note
The Board typically approves the minutes of the previous meeting at the
beginning of every Board meeting; therefore, the list below does not
normally contain details from the minutes of the most recent Board meeting.
Meeting times vary, the exact schedule is available to ASF Members and Officers, search for "calendar" in the Foundation's private index page (svn:foundation/private-index.html).
Report was filed, but display is awaiting the approval of the Board minutes.

* Presented Nemo at Berlin Beam Summit 2019.
* Discussion with Google Beam, Shopify, Seznam,cz developers
At the Beam Summit Europe 2019, which occurred in Berlin from
June 19th to the 20th, there had been many discussions regarding
Nemo from engineers working in the industry, as well as
with engineers working with Apache Beam. There had been people
from various companies, as Shopify and Seznam.cz, facing problems
as large-shuffle and data skew, and had shown a lot of interest
in using the Apache Nemo runner. Also, in the following ApacheCon
summit happening in Vegas in September, the Apache Beam team will
demonstrate running their workloads using the Apache Nemo runner.
### How has the project developed since the last report?
* Integrate Apache Crail with Nemo
* Off-heap support to improve shuffle speed
* DirectByteBufferInput/OutputStream for
Off-heap SerializedMemoryStore
* Off-heap SerializedMemoryStore
* Off-heap memory management (reuse ByteBuffer)
* Separation of JVM heap region and off-heap memory region
* Enable Nemo single-stage programs to run on a serverless
framework, AWS Lambda
* Refactor Executor to support different types of execution
environment
* Add a Lambda Executor
* Add a compiler pass for Lambda
* Progress on a ML-based smart compiler

IPMC/Shepherd notes:
Dave Fisher: AFAICT the SGA has not been provided and a mentor has
advised that this can wait until graduation.
I don't think that is correct and it is not the same as the guidance
given to other podlings like Heron.

Nemo is a data processing system to flexibly control the runtime behaviors of
a job to adapt to varying deployment characteristics.
Nemo has been incubating since 2018-02-04.
Three most important issues to address in the move towards graduation:
1. Grow the community
2. Create a first Apache release
3. Donate code to ASF
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
None.
How has the community developed since the last report?
* Committers actively involved in mailing lists
* Committers actively started to send PRs and do code reviews
* PPMC accepted a GSoC student to work on Nemo web UI issues
How has the project developed since the last report?
* Progress towards supporting Spark DSL programs
* Optimization policy for geo-distributed data analytics
* Optimization policy for skew handling
* Working on a paper that describes the design and
implementation of Nemo
