>>>>>
>>>>> We believe that submitting Dataflow as an Apache project will

>>>>> immediate, worthwhile, and substantial contribution to the open
>>>>>source
>>>>> community. As an incubating project, we believe Dataflow will have a
>>> better
>>>>> opportunity to provide a meaningful contribution to OSS and also
>>> integrate
>>>>> with other Apache projects.
>>>>>
>>>>> In the long term, we believe Dataflow can be a powerful abstraction

>>>>>
>>>>> == Initial Goals ==
>>>>>
>>>>> We are breaking our initial goals into immediate (< 2 months),
>>> short-term
>>>>> (2-4 months), and intermediate-term (> 4 months).
>>>>>
>>>>> Our immediate goals include the following:
>>>>>
>>>>> * Plan for reconciling the Dataflow Java SDK and various runners into
>>> one
>>>>> project
>>>>>
>>>>> * Plan for refactoring the existing Java SDK for better
>>>>>extensibility by
>>>>> SDK and runner writers
>>>>>
>>>>> * Validating all dependencies are ASL 2.0 or compatible
>>>>>
>>>>> * Understanding and adapting to the Apache development process
>>>>>
>>>>> Our short-term goals include:
>>>>>
>>>>> * Moving the newly-merged lists, and build utilities to Apache
>>>>>
>>>>> * Start refactoring codebase and move code to Apache Git repo
>>>>>
>>>>> * Continue development of new features, functions, and fixes in the
>>>>> Dataflow Java SDK, and Dataflow runners
>>>>>
>>>>> * Cleaning up the Dataflow SDK sources and crafting a roadmap and
>>>>>plan
>>> for
>>>>> how to include new major ideas, modules, and runtimes
>>>>>
>>>>> * Establishment of easy and clear build/test framework for Dataflow
>>>>>and
>>>>> associated runtimes; creation of testing, rollback, and validation
>>> policy
>>>>>
>>>>> * Analysis and design for work needed to make Dataflow a better data

>>>>>
>>>>> Finally, we have a number of intermediate-term goals:

>>>>> * Roadmapping, planning, and execution of integrations with other OSS

>>>>> non-OSS projects/products
>>>>>
>>>>> * Inclusion of additional SDK for Python, which is under active
>>> development
>>>>>
>>>>> == Current Status ==
>>>>>
>>>>> === Meritocracy ===
>>>>>
>>>>> Dataflow was initially developed based on ideas from many employees
>>> within
>>>>> Google. As an ASL OSS project on GitHub, the Dataflow SDK has
>>>>>received
>>>>> contributions from data Artisans, Cloudera Labs, and other individual
>>>>> developers. As a project under incubation, we are committed to
>>>>>expanding
>>>>> our effort to build an environment which supports a meritocracy. We
>>>>>are
>>>>> focused on engaging the community and other related projects for
>>>>>support
>>>>> and contributions. Moreover, we are committed to ensure contributors
>>>>>and
>>>>> committers to Dataflow come from a broad mix of organizations
>>>>>through a
>>>>> merit-based decision process during incubation. We believe strongly
>>>>>in
>>> the
>>>>> Dataflow model and are committed to growing an inclusive community of
>>>>> Dataflow contributors.
>>>>>
>>>>> === Community ===
>>>>>
>>>>> The core of the Dataflow Java SDK has been developed by Google for
>>>>>use
>>> with
>>>>> Google Cloud Dataflow. Google has active community engagement in the
>>>>>SDK
>>>>> GitHub repository (

>>>>> ),
>>>>> on Stack Overflow (
>>>>> http://stackoverflow.com/questions/tagged/google-cloud-dataflow) and
>>> has
>>>>> had contributions from a number of organizations and indivuduals.
>>>>>
>>>>> Everyday, Cloud Dataflow is actively used by a number of

>>>>> will allow us to consolidate existing Dataflow-related work, grow the
>>>>> Dataflow community, and deepen connections between Dataflow and other
>>> open
>>>>> source projects.

>>>>> === Core Developers ===
>>>>>
>>>>> The core developers for Dataflow and the Dataflow runners are:

>>>>> our commitment to open source software.
>>>>>
>>>>> === Homogeneous Developers ===
>>>>>
>>>>> The majority of committers in this proposal belong to Google due to
>>>>>the
>>>>> fact that Dataflow has emerged from several internal Google projects.
>>> This
>>>>> proposal also includes committers outside of Google who are actively
>>>>> involved with other Apache projects, such as Hadoop, Flink, and
>>>>>Spark.
>>> We
>>>>> expect our entry into incubation will allow us to expand the number

>>>>> Additionally, separation of the Dataflow SDK from Google Cloud
>>>>>Dataflow
>>>>> allows us to focus on the open source SDK and model and do what is
>>>>>best
>>> for
>>>>> this project.
>>>>>
>>>>> === Reliance on Salaried Developers ===
>>>>>
>>>>> The Dataflow SDK and Dataflow runners have been developed primarily
>>>>>by
>>>>> salaried developers supporting the Google Cloud Dataflow project.
>>>>>While
>>> the
>>>>> Dataflow SDK and Cloud Dataflow have been developed by different
>>>>>teams

>>>>> directory of the Dataflow SDK (
>>>>>
>>> 
>>>https://github.com/GoogleCloudPlatform/DataflowJavaSDK/tree/master/contr

>>>>> )
>>>>> contains items from free-time contributors. Moreover, seperate
>>>>>projects,
>>>>> such as ScalaFlow (https://github.com/darkjh/scalaflow) have been

>>>>> around the Dataflow model and SDK. We expect our reliance on salaried
>>>>> developers will decrease over time during incubation.
>>>>>
>>>>> === Relationship with other Apache products ===
>>>>>
>>>>> Dataflow directly interoperates with or utilizes several existing
>>>>>Apache
>>>>> projects.
>>>>>
>>>>> * Build
>>>>>
>>>>> ** Apache Maven
>>>>>
>>>>> * Data I/O, Libraries
>>>>>
>>>>> ** Apache Avro
>>>>>
>>>>> ** Apache Commons
>>>>>
>>>>> * Dataflow runners
>>>>>
>>>>> ** Apache Flink
>>>>>
>>>>> ** Apache Spark
>>>>>
>>>>> Dataflow when used in batch mode shares similarities with Apache
>>>>>Crunch;
>>>>> however, Dataflow is focused on a model, SDK, and abstraction layer
>>> beyond
>>>>> Spark and Hadoop (MapReduce.) One key goal of Dataflow is to provide
>>>>>an
>>>>> intermediate abstraction layer which can easily be implemented and
>>> utilized
>>>>> across several different processing frameworks.
>>>>>
>>>>> === An excessive fascination with the Apache brand ===
>>>>>
>>>>> With this proposal we are not seeking attention or publicity.
>>>>>Rather, we
>>>>> firmly believe in the Dataflow model, SDK, and the ability to make
>>> Dataflow
>>>>> a powerful yet simple framework for data processing. While the
>>>>>Dataflow
>>> SDK
>>>>> and model have been open source, we believe putting code on GitHub
>>>>>can
>>> only
>>>>> go so far. We see the Apache community, processes, and mission as
>>> critical
>>>>> for ensuring the Dataflow SDK and model are truly community-driven,
>>>>> positively impactful, and innovative open source software. While
>>>>>Google
>>> has
>>>>> taken a number of steps to advance its various open source projects,
>>>>>we
>>>>> believe Dataflow is a great fit for the Apache Software Foundation
>>>>>due
>>> to
>>>>> its focus on data processing and its relationships to existing ASF
>>>>> projects.
