> == Abstract ==
> The following proposal is about Apache !DirectMemory, a Java
> !OpenSource multi-layered cache implementation featuring off-heap
> memory storage (a-la Terracotta !BigMemory) to enable caching of Java
> objects without degrading JVM performance
>
> == Proposal ==
> !DirectMemory's main purpose is to to act as a second level cache
> (after a heap based one) able to store large amounts of data without
> filling up the Java heap and thus avoiding long garbage collection
> cycles. Although serialization has a runtime cost store/retrieve
> operations are in the sub-millisecond range being pretty acceptable in
> every usage scenario even as a first level cache and, most of all,
> outperforms heap storage when the count of the entries goes over a
> certain amount. !DirectMemory implements cache eviction based on a
> simple LFU (Least Frequently Used) algorythm and also on item
> expiration. Included in the box is a small set of utility classes to
> easily handle off-heap memory buffers.
>
> == Background ==
> !DirectMemory is a project was born in the 2010 thanks to Raffaele P.
> Guidi initial effort under
> [[https://github.com/raffaeleguidi/!DirectMemory/|GitHub]] and already
> licensed under the Apache License 2.0.
>
> == Rationale ==
> The rationale behind !DirectMemory is bringing off-heap caching to the
> open source world, empowering FOSS developers and products with a tool
> that enables breaking the heap barrier and override the JVM garbage
> collection mechanism collection - which could be useful in scenarios
> where RAM needs are over the usual limits (more than 8, 12, 24gb) and
> to ease usage of off-heap memory in general

> == Meritocracy ==
> As a majority of the initial project members are existing ASF
> committers, we recognize the desirability of running the project as a
> meritocracy. We are eager to engage other members of the community
> and operate to the standard of meritocracy that Apache emphasizes; we
> believe this is the most effective method of growing our community and
> enabling widespread adoption.

> = Known Risks =
> == Orphaned Products ==
> !DirectMemory does not have any reported production usage, yet, but is
> getting traction with developers and being evaluated by potential
> users and thus the risks of it being orphaned are minimal
>
> == Inexperience with Open Source ==
> All of the committers have experience working in one or more open
> source projects inside and outside ASF.
>
> == Homogeneous Developers ==
> The list of initial committers are geographically distributed across
> the Europe with no one company being associated with a majority of the
> developers. Many of these initial developers are experienced Apache
> committers already and all are experienced with working in distributed
> development communities.
>
> == Reliance on Salaried Developers ==
> To the best of our knowledge, none of the initial committers are being
> paid to develop code for this project.
>
> == Relationships with Other Apache Products ==
> !DirectMemory fits naturally in the ASF because it could be
> successfully employed together with a large number of ASF products
> ranging from JCS - as a new cache region between the heap and indexed
> file ones, to ORM systems like Cayenne (i.e. replacing current OSCache
> based implementation), Apache JDO and JPA implementations and also
> java based databases (i.e. Derby) and all systems managing large
> amounts of data from Hadoop to Cassandra
>
> == A Excessive Fascination with the Apache Brand ==
> While the Apache Software Foundation would be a good home for the
> !DirectMemory project it already has some traction and it could live
> on its own - however we see reciprocal benefits for both the ASF and
> the project in adopting the brand to better reach the community
