Subject [Incubator Wiki] Update of "SilkProposal" by KonstantinIBoudnik
Date Fri, 19 Sep 2014 04:35:59 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Incubator Wiki" for change notification.

The "SilkProposal" page has been changed by KonstantinIBoudnik:

New page:
= Silk Apache Incubator Proposal =

== Abstract ==

Apache Silk will be a unified In-Memory Data Fabric providing high-performance, distributed
in-memory data management software layer between various data sources and user applications.

== Proposal ==

Apache Silk is written mostly in Java and Scala with small amount of C++ code and will initially
combine the following technologies under one unified umbrella:
 * In-Memory Data Grid
 * In-Memory Compute Grid
 * In-Memory Streaming Processing
This unified in-memory fabric will provide high-performance, distributed in-memory software
layer that sits in between various data sources and user applica tions. Data sources can include
SQL RDBMS, NoSQL, or HDFS. Applications APIs will be available for Java (and Java-based scripting
languages), Scala, C++ and .NET (C#).

GridGain Systems, Inc. submits this proposal to donate its Apache 2.0-licensed open source
project generally known as “GridGain In-Memory Computing Platform”, its source code, documentation,
and websites to the Apache Software Foundation (“ASF”) with the goal of extending the
vibrant open source community around this technology ultimately governed by “Apache Way”.
Proposed Naming

We have been advised by the ASF mentors that the name “Silk” may not be ideal because
the name may be too generic and may not pass ASF legal check. Here are the alternatives that
we have come up with and any of those will be acceptable for the project pending the ASF legal
green light:

 * Apache Silk (preferable name)
 * Apache Sylk
 * Apache Memstor
 * Apache Ignite

== Background & Rationale ==

In-Memory Data Fabric is a natural and evolutionary consolidation of various “in-memory
technologies” from the last decade. From simple local caching (JSR-107), to distributed
caching, to data grids and databases, to streaming and plug-n-play acceleration - the in-memory
space has grown quite dramatically.

With rapid advances in NVRAM and significant price reduction of traditional DRAM on one hand,
and growing sophistication and demand for faster data processing on another - many users of
these silo-ed technologies and products started to look for a “strategic approach” to
in-memory - an in-memory data fabric - that would provide suitable APIs for different types
of payloads: from data caching, to data grids, to in-memory SQL data stores, to HPC, to streaming

With expensive and proprietary in-memory computing products from companies like Oracle, SAP,
Microsoft, and IBM -  the developers worldwide need an unhindered access to advanced open
source in-memory software technology, the technology they can trust to develop with and deploy
for critical applications.
Current Status

Apache Silk will be based on the technology that is currently developed by GridGain Systems
and available under Apache 2.0 license ( The software has been in
development since 2007 and in production since 2009. It is currently used by over 500 production
deployments with over 1,000,000 downloads to date, and with over 20,000,000 GridGain nodes
started in the last 5 years.
Initial Goals

The number one goal during ASF incubation will coalesce around building a true active and
vibrant community governed by the “Apache Way”. The initial development goals for Silk
primarily revolve around migrating the existing code base, documentation, and refactoring
of the existing internal build, test & release processes. We believe these initial goals
are sufficiently difficult to be considered early milestones.

Some of the specific initial goals include:
 * Migrate the existing Silk code base to the ASF.
 * Refactor development, testing, build and release processes to work in ASF.
 * Attract developer and user interest in the new Apache Silk project.
 * Road map the integration efforts with “sister” projects in ASF eco-system like Storm
and Spark.
 * Incorporate externally developed features into the core Apache Silk project.

== Known Risks ==

This proposal is not without its risks, some of which are outlined below.

The current list of committers are primarily from GridGain Systems. One of the key purposes
of proposing Silk for incubation is to attract new committers and spur the adoption of Silk.
The ASF has a well-deserved reputation of fostering and building open source communities,
which makes it the ideal location to attempt this community bootstrap.

Most of the initial committers are supported by their employers to work on Silk, and may be
assigned to work on other priorities. However, the employers of these salaried individuals
- GridGain Systems or current customers and users - have a vested interest in seeing Silk
thrive as a long-term, growing project.

GridGain Systems understands that their employees are acting as individuals when contributing
to Apache projects. As a major initial contributor GridGain Systems is prepared to bring additional
staff on board to assist with Silk development to ensure its active growth.

One of the key motivators in creating the Silk project as part of the Incubator is to leverage
the vendor-neutral nature of the ASF. The ASF has a strong and recognized brand as being a
leader in open source, and by hosting Silk at the ASF, we hope to attract developers to build
a viable community for the project.

== Meritocracy ==

Apache Silk plans to adopt the policy that encourages an environment that supports a meritocracy.
We intend to actively ask the community  for help, listing/specifying the work that needs
to be done, and  keeping track of and encouraging members of the community who make any contributions.
Community & Core Developers

GridGain project has been actively building community of users in the last couple of years
with an active StackOverflow group, support groups, and Meetups (
This group includes active members of Apache community as well. We strongly believe that this
community will grow and develop substantially as part of Apache family and that’s our commitment.
