What the board has decided about this committee or office, and the reports it filed, most recent first. Generated from the published minutes.
These categorised views are best effort. They are read from the published minutes by a program, and what it can attribute to a committee depends on how each resolution happens to be worded — so a page may be incomplete, and nothing here overrides the minutes themselves. The raw minutes are the source of truth.
Please note. The board approves the minutes of a meeting at the meeting after it, and they are published then - so the most recent meeting is not usually here. ASF Members can read the draft in the board's own repository until it is.

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
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
Apache DirectMemory is an off-heap cache implementation for the JVM * General Information Development and mailing lists traffic are mostly quiet.

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

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

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.
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).

off-heap memory management (a-la BigMemory) to enable efficient handling
of a large number of java objects without affecting JVM garbage collection
performance.
There is only one important issue to address in the move towards graduation
Understanding process/decision making guidelines (new committer process
is undergoing testing, release process still yet to be worked out)
Any issues that the Incubator PMC or ASF Board might wish/need to be aware of
None
How has the community developed since the last report
