 WHEREAS, the Project Management Committee of the Apache DirectMemory
 project has chosen by vote to recommend moving the project to the

 of the Foundation to continue the Apache DirectMemory project due to
 lack of developer interest;

 NOW, THEREFORE, BE IT RESOLVED, that the Apache DirectMemory project is
 hereby terminated; and be it further

 RESOLVED, that the Attic PMC be and hereby is tasked with oversight
 over the software developed by the Apache DirectMemory Project; and be it
 further

 RESOLVED, that the office of "Vice President, Apache DirectMemory" is
 hereby terminated; and be it further

 RESOLVED, that the Apache DirectMemory PMC is hereby terminated.

 Special Order 7D, Terminate the Apache DirectMemory Project,
 was approved by Unanimous Vote of the directors present.

Apache DirectMemory is an off-heap cache implementation for the JVM

* General Information

As no one volounteered to take over the PMC chair role we decided to move
the project to the attic

* Issues
Development is stuck since long time and developer's appeal is lost. No one,
including me, seems to have time to devote to the project

* Committers or PMC members change
Last added PMC PMC member was Noctarius (Cristoph Engelbert) on 2013-09-25

* Releases
Release 0.2 has seen the light on 2013-09-17

17 Jun 2015 [Raffaele P. Guidi / Rich]

Apache DirectMemory is an off-heap cache implementation for the JVM

* General Information

We had only one contact on the developer's list since april. A formal votation
has been made about retiring to the attic and it held only 3 votes (all in
favour of retirement). Some team members discussed proposals to improve
documentation in order to improve our appeal to developers and a call for help
has been submitted to the developers list but nothing much happened. I
proposed to step back as PMC chair but no one volunteered to take over the
role

* Issues
Development is stuck since long time and developer's appeal is lost. No one,
including me, seems to have time to devote to the project. I honestly think
it's time to retire the project or, at least, for me to retire as PMC chair

* Committers or PMC members change
Last added PMC PMC member was Noctarius (Cristoph Engelbert) on 2013-09-25

* Releases
Release 0.2 has seen the light on 2013-09-17

@Rich: need a resolution for the Attic

Apache DirectMemory is an off-heap cache implementation for the JVM

* General Information
DirectMemory is being evaluated by project jackrabbit for integration of off-heap
memory into OAK.
Another, more performant back-end implementation is being contributed by
noctarius

* Issues
Development is not moving really fast and adoption is still quite limited to other
apache projects - although more than some interesting integrations have been
contributed. Any help would be appreciated, though, in suggestions, spreading the word,
testing and facilitating the adoption of the platform

* Committers or PMC members change
Noctarius has been added as a new PMC member on 2013-09-25

* Releases
Release 0.2 has seen the light on 2013-09-17 - this is the first one since we left incubation

Apache DirectMemory is an off-heap cache implementation for the JVM

* General Information
DirectMemory is being evaluated by project jackrabbit for integration of
off-heap memory into OAK.

Another, more performant back-end implementation is being contributed by
noctarius

* Issues
Development is not moving really fast and adoption is still quite limited
to other apache projects - although more than some interesting integrations have been
contributed. It has to be said that DirectMemory is a niche product - its
target is people and organizations that need to enable their application to handle
large (gigabytes) quantities of objects into memory and it competes in the same space
of terracotta, jboss, memcached and other big players with strong corporate backing
and sponsorship. We feel that we accomplished at least, being the first open source
offheap cache implementation, the goal to bring big memory to the masses, forcing,
in a way, companies to offer free tiers of commercial products (as bigmemory go).

We feel that we are moving, although slowly, and we are making things move.
Any help would be appreciated, though, in suggestions, spreading the word,
testing and facilitating the adoption of the platform

* Releases
 No releases since july 2012. Release 0.2 is planned for the end of the
month - this will be the first one since we left incubation

* General Information
Community interest seems to be still high but nothing serious happened in
code and in the mailing list except for a proposal to contribute some
benchmarks and performance testing that, since we are still far away from a
release, could really help.

* New Committers
 * None

* Project Branding Requirements
 Already completed.

* Issues
 No board level issues at this time.

AI: Doug: let PMCs know to leave off branding from board reports unless there are issues

Apache DirectMemory is an off-heap cache implementation for the JVM. It
features direct memory management (a-la BigMemory) to enable efficient
handling of a large number of Java objects without affecting JVM garbage
collection performance.

Community interest has increased since TLP graduation, we are receiving
interesting contributions on the mailing list. A proposal to join forces
with another interesting although young project (the lightning serializer)
has been accepted by the author and it is going to be defined as a
subproject.  Synergies with other projects are being explored too (kryo, another
serializer, at the end DirectMemory is all about serializing objects in
off-heap memory and back).

We are probably better defining the technical direction of the project even
though there's still plenty of work to do.

19 Sep 2012 [Raffaele P. Guidi / Sam]

Apache DirectMemory is an off-heap cache implementation for the JVM. It
features direct memory management (a-la BigMemory) to enable efficient
handling of a large number of java objects without affecting JVM garbage
collection performance.

DirectMemory graduated August 15th and not much happened since - except for
the payoff that has been considerably shortened. Next steps will be in
gathering community and development team proposals to better identify a
direction for our efforts (which has sometimes been an issue, as pointed
out during the graduation voting process) and, maybe, spread adoption
(which is very limited at the moment regardless of the good number of
integrations developed).

All tasks regarding TLP graduation have been completed (including svnpubsub
for both distribution and site deployment).

AI Bertrand: what does "payoff that has been considerably shortened" mean?
