Subject [PROPOSAL] Silk as new Incubator project
Date Fri, 19 Sep 2014 04:40:27 GMT
I would like to propose Silk as an Apache Incubator project. The new 
proposal is added to and
is duplicated below.


= 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
 * 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

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

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.

== Existing Documentation ==

Current documentation for GridGain project can be found here: We intend to migrate it into ASF

== Initial Source ==

Initial Apache 2.0 licensed source code can be found here:

== External Dependencies ==

Here’s the list of 3rd party JAR-only dependencies:
 * Apache Hadoop
 * Apache Commons
 * H2
 * JTS
 * Apache Lucene
 * Spring

Here’s the list of the all licenses for 3rd party libraries currently used:
 * Apache 2.0
