= Accumulo Proposal =
== Abstract ==
Accumulo is a distributed key/value store that provides expressive,
cell-level access labels.
== Proposal ==
Accumulo is a sorted, distributed key/value store based on Google's
BigTable design. It is built on top of Apache Hadoop, Zookeeper, and
Thrift. It features a few novel improvements on the BigTable design in
the form of cell-level access labels and a server-side programming
mechanism that can modify key/value pairs at various points in the data
management process.
== Background ==
Google published the design of BigTable in 2006. Several other open
source projects have implemented aspects of this design including HBase,
CloudStore, and Cassandra. Accumulo began its development in 2008.
== Rationale ==
There is a need for a flexible, high performance distributed key/value
store that provides expressive, fine-grained access labels. The
communities we expect to be most interested in such a project are
government, health care, and other industries where privacy is a
concern. We have made much progress in developing this project over the
past 3 years and believe both the project and the interested communities
would benefit from this work being openly available and having open
development.
== Current Status ==
=== Meritocracy ===
We intend to strongly encourage the community to help with and
contribute to the code. We will actively seek potential committers and
help them become familiar with the codebase.
=== Community ===
A strong government community has developed around Accumulo and training
classes have been ongoing for about a year. Hundreds of developers use
Accumulo.
=== Core Developers ===
The developers are mainly employed by the National Security Agency, but
we anticipate interest developing among other companies.
=== Alignment ===
Accumulo is built on top of Hadoop, Zookeeper, and Thrift. It builds
with Maven. Due to the strong relationship with these Apache projects,
the incubator is a good match for Accumulo.
== Known Risks ==
=== Orphaned Products ===
There is only a small risk of being orphaned. The community is
committed to improving the codebase of the project due to its fulfilling
needs not addressed by any other software.
=== Inexperience with Open Source ===
The codebase has been treated internally as an open source project since
its beginning, and the initial Apache committers have been involved with
the code for multiple years. While our experience with public open
source is limited, we do not anticipate difficulty in operating under
Apache's development process.
=== Homogeneous Developers ===
The committers have multiple employers and it is expected that
committers from different companies will be recruited.
=== Reliance on Salaried Developers ===
The initial committers are all paid by their employers to work on
Accumulo and we expect such employment to continue. Some of the initial
committers would continue as volunteers even if no longer employed to do so.
=== Relationships with Other Apache Products ===
Accumulo uses Hadoop, Zookeeper, Thrift, Maven, log4j, commons-lang,
-net, -io, -jci, -collections, -configuration, -logging, and -codec.
=== Relationship to HBase ===
Accumulo and HBase are both based on the design of Google's BigTable, so
there is a danger that potential users will have difficulty
distinguishing the two. Some of the key areas in which Accumulo differs
from HBase are discussed below. It may be possible to incorporate the
desired features of Accumulo into HBase. However, the amount of work
required would slow development of HBase and Accumulo considerably. We
believe this warrants a podling for Accumulo at the current time. We
expect active cross-pollination will occur between HBase and podling
Accumulo and it is possible that the codebases and projects will
ultimately converge.
Access Labels
Accumulo has an additional portion of its key that sorts after the
column qualifier and before the timestamp. It is called column
visibility and enables expressive cell-level access control.
Authorizations are passed with each query to control what data is
returned to the user. The column visibilities are boolean AND and OR
combinations of arbitrary strings (such as (AB)|C) and authorizations
are sets of strings (such as {C,D}).

Thanks, Doug --- = Accumulo Proposal = == Abstract == Accumulo is a distributed key/value store that provides expressive, cell-level access labels. == Proposal == Accumulo is a sorted, distributed key/value store based on Google's BigTable design.

It features a few novel improvements on the BigTable design in the form of cell-level access labels and a server-side programming mechanism that can modify key/value pairs at various points in the data management process. == Background == Google published the design of BigTable in 2006. Several other open source projects have implemented aspects of this design including HBase, CloudStore, and Cassandra. Accumulo began its development in 2008. == Rationale == There is a need for a flexible, high performance distributed key/value store that provides expressive, fine-grained access labels. The communities we expect to be most interested in such a project are government, health care, and other industries where privacy is a concern. We have made much progress in developing this project over the past 3 years and believe both the project and the interested communities would benefit from this work being openly available and having open development. == Current Status == === Meritocracy === We intend to strongly encourage the community to help with and contribute to the code. We will actively seek potential committers and help them become familiar with the codebase. === Community === A strong government community has developed around Accumulo and training classes have been ongoing for about a year. Hundreds of developers use Accumulo. === Core Developers === The developers are mainly employed by the National Security Agency, but we anticipate interest developing among other companies. === Alignment === Accumulo is built on top of Hadoop, Zookeeper, and Thrift.

While our experience with public open source is limited, we do not anticipate difficulty in operating under Apache's development process. === Homogeneous Developers === The committers have multiple employers and it is expected that committers from different companies will be recruited. === Reliance on Salaried Developers === The initial committers are all paid by their employers to work on Accumulo and we expect such employment to continue. Some of the initial committers would continue as volunteers even if no longer employed to do so. === Relationships with Other Apache Products === Accumulo uses Hadoop, Zookeeper, Thrift, Maven, log4j, commons-lang, -net, -io, -jci, -collections, -configuration, -logging, and -codec. === Relationship to HBase === Accumulo and HBase are both based on the design of Google's BigTable, so there is a danger that potential users will have difficulty distinguishing the two. Some of the key areas in which Accumulo differs from HBase are discussed below. It may be possible to incorporate the desired features of Accumulo into HBase.
