Apache Mnemonic is an advanced hybrid memory storage oriented library,
we've proposed a non-volatile/durable Java object model and durable
computing service that bring many advantages to significantly improve
the performance of massive real-time data
processing/analytics. developers are able to use this library to design
their cache-less, SerDe-less and native-direct computing high
performance applications.
Three most important issues to address in the move towards graduation:
1. Apache releases: we have release version 0.4.0-incubating
2. Integrated with Hadoop as Mapreduce Input/Output formatters.
3. Introduced Mnemonic to potential developers and users.
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
No.
How has the community developed since the last report?
Our last report was in Dec. Since then
* Two more developers are going to contribute code.
* We need to encourage more discussion on the dev list in the coming months
How has the project developed since the last report?
* Upgraded MemChunkHolder/MemBufferHolder to DurableChunk/DurableHolder
* Provided mnemonic-hadoop-mapreduce module with testcases
* and other bugfixes, features, improvements
How would you assess the podling's maturity?

One year milestone as podling this month. Community growth has been
slow and activity dominated by one to two committers. Not clear how
active the mentors are in helping the podling - only two mentors
signed off on the report last quarter.

Mentors have not been active, including myself. We may want to
solicit new or additional mentors for this podling.

No.
How has the community developed since the last report?
Our last report was in April. Since then
* Two more developers are going to join our community.

How has the project developed since the last report?
* Added durable native sorting service (n-dim linked data) with
testcases
* Removed the 3rd Maven repository and use Maven central repository
only
* DOM and DNCS could apply to volatile memory service except fixed k-v
store
* Added a bench workload to verify the benefits from DNCS with
scripts, generator
* Added a sys-vmem service that makes it possible to utilize system

* Added a script to bundle signed portable artifacts for maven
repository submitting
* and other bugfixes, features, improvements

Mnemonic is a Java based non-volatile memory library for in-place structured data processing and computing. Mnemonic has been incubating since 2016-03-03. On 05/24/2016, we released our first official build at https://dist.apache.org/repos/dist/release/incubator/mnemonic/0.1.2-incubating/ Various metrics for May are as follows: (5/3-5/31/2016) +------------------------------------------+ | Metric | counts | +------------------------------------------+ | Non Merge Commits | 23 | | Contributors | 3 | | Jira New Issues | 18 | | Resolved Issues | 18 | | Pull Requests merged | 0 | | Pull Requests proposed | 0 | +------------------------------------------+ Three most important issues to address in the move towards graduation: 1. Apache releases: Community voted and released Mnemonic-0.1.2-incubating 2. Expand and build strong community, keep active dev list discussions 3. Develop new features: We are working in Native computing layer design Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of? There are no issues requiring board attention at this time How has the community developed since the last report? Yanping and Gary presented Mnemonic project at ApacheCon Big Data Conference. Yanping presented at In-Memory Computing Summit. Both talks were well received. Several developers approached us to ask additional details on how Mnemonic worked for Spark. They are interested to see if we are able to successfully integrate Mnemonic into other projects. While we are focusing on develop new features, we will try to contact other projects' communities to explore integration opportunities. As the official release is done this month, for the next 3 months we expect integration activities will be increased. How has the project developed since the last report? We have been focusing the first Apache release over the past weeks. We also explored ideas on design native computing layer which will further enhance durable Java object model on large non-volatile memory. Date of last release: 2016-05-24 When were the last committers or PMC members elected? No election, the project is still in early stage of developing.

Three most important issues to address in the move towards graduation:
1. Apache releases: we are preparing 0.1.0 release
2. Expand and build strong community, keep active dev list discussions,
adding new contributors
a. Mnemonic website is up: http://mnemonic.incubator.apache.org/
b. Mnemonic cwiki is up:
https://cwiki.apache.org/confluence/display/MNEMONIC/Apache+Mnemonic+Ho
me
3. Develop new features: We are working in Native computing layer design.
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware
of?
Everything is on track, nothing urgent at this time.
How has the community developed since the last report?
1. We completed setting up infrastructure. Both project website and cwiki
are up running. We are working on adding contents and documentation to
the sites so new contributors and community members can get better view
of what this project is and how to get involved.
2. We realized, unlike other application level projects, library (or API)
projects traditionally had less contributors until certain amount of
adopters successfully integrated those libraries. We plan to help some
integrations, such as HBase, Arrow, etc. after our first official code
release.
3. We submitted 2 proposals for Strata Hadoop World NYC.
4. We will present Mnemonic project in upcoming ApacheCon Big Data
conference on 5/11.
How has the project developed since the last report?
We are designing the native computing infrastructure, built native
computing interface code.
In preparing first official release:
1. Defined coding guidelines for the project. Reformatted all code based
on defined coding style.
2. Added the checkstyle to automate the checking process.
3. Formalized the names of annotations, classes and methods.
4. Removed the dependency of property mnemonic.core.version.
5. Added a new profile for artifacts releasing and signing.
6. Added release plugin and configuration for releasing.
Date of last release:
No release yet, working on 0.1.0 release
When were the last committers or PMC members elected?
No election, since the project is still in early stage of developing.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
Everything is on track, nothing urgent at this time.
How has the community developed since the last report?
The project is in early stage in setting up the infra. In addition to
contributors listed in Mnemonic proposal, we had one new contributor
joined us. We are actively discuss with Arrow community in dev list for
the idea on integration. Apache Arrow community is very interested in
Mnemonic integration for extending Arrow into persistent memory and
storage.
How has the project developed since the last report?
We ported source code in Apache on 3/24 after SGA was filed on 3/23. We
are doing several refactorings and defining coding guidelines to fit
Apache project standard.
We are working on enabling Apache Arrow to use Mnemonic as underlying
pooling mechanism.
We are designing the native computing infrastructure, built native
computing interface code.
Bug tracking JIRA setup was done, 13 issues were filed. 4 issues were
solved.
Mailing list discussions are happening actively related to infrastructure,
code standard, features for the project.
Date of last release:
No release yet, working on 0.1.0 release
When were the last committers or PMC members elected?
No election, since the project is just starting. As part of incubation
process, initial committers and contributors were proposed and added.
