Formal board meeting minutes from 2010 through present. Please Note: The board typically approves minutes from one meeting during the next board meeting, so minutes will be published roughly one month later than the scheduled date. Other corporate records are published, as is an alternate categorized view of all board meeting minutes.

Mnemonic

15 Mar 2017

Report was filed, but display is awaiting the approval of the Board minutes.

21 Dec 2016

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 several 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 0.3.0-incubating
 2. Improved dev. docker to facilitate development.
 3. provided information to potential customers e.g. bank user, other
    project's Apache committers

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 April. Since then

 * Two more developers are going to join our community.
 * We need to encourage more discussion on the dev list in the coming months

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
   memory for DNCS in an unified way
 * 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.

 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.

 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.
