     Comments: Currently waiting on SGA (pinged for status, but no response yet). Little activity on mailing lists so
               far. Decision making seems to be taking place off-list (3 non-Apache releases). I concur with Dave 
               Fisher that monthly reporting should be considered (although this is report #2 in their initial monthly
               reporting cycle).

IPMC/Shepherd notes:

  Dave Fisher:  It seems that with 3 non-apache releases while there is not even ay use of Apache resources that Heron ought to focus on migration. I think that they should be monthly until the code is moved.

HTrace

HTrace is a tracing framework intended for use with distributed systems
written in java.

HTrace has been incubating since 2014-11-11.

Three most important issues to address in the move towards graduation:

 1. Continue to grow the Apache HTrace community
 2. Continue to explore projects integrating Apache HTrace
 3. Continue to develop and release stable Apache HTrace incubating artifacts

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware
of?

 In a DISCUSSION thread on our dev list [1], one of us suggested
 moving the podling htrace to the attic because of inactivity.

 A healthy back and forth suggested that we are not
 dead yet, that we cut back our scope radically, and
 that we give it another try before calling it quits.

1. https://s.apache.org/9ybr

How has the community developed since the last report?

 Mailing lists continue quiet (bar the above noted thread).

How has the project developed since the last report?

 No development.

     "...A healthy back and forth suggested that we are not dead yet, 
     that we cut back our scope radically, and that we give it another 
     try before calling it quits." I think HTrace may have a good opportunity 
     to come back to life if the above cut backs are implemented.

OpenWhisk  

OpenWhisk is an open source, distributed Serverless computing platform able to execute application logic (Actions) in response to events (Triggers) from external sources (Feeds) or HTTP requests governed by conditional logic (Rules). It provides a programming environment supported by a REST API-based Command Line Interface (CLI) along with tooling to support packaging and catalog services.  Additionslly, it now provides options to host the platform components as Docker containers on various Container Frameworks such as Mesos, Kunernetes, and Compose.
OpenWhisk has been incubating since 2016-11-23.

   Three most important issues to address in the move towards graduation:    

    1. Est. release process for ZIP of source code
    2. Est. release process for Docker and other platform binaries
    3. Increase additional company and individual Contributors to maintain all project repos.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be  aware of?    

    - It had been our intent to have Apache host our staging (and move it out of disparate private builds within various companies). However, INFRA indicates they only typically allocate 1 VM per project for use with demos and minor things. They indicated that typically a donation is in order (ala. Spark).
      -- Note: the desire for this staging capability was expressed in the Incubator submission where we anticipated needing ~12 VMs to host each platform component and be able to load balance/schedule Functional code as part of the OpenWhisk Serverless (across multiple supported language runtimes). This would also be needed to effectively test auto-scaling/load balancing and container pools and to get accurate performance test measures.
    - Formal hand-off of OpenWhisk trademark/logo from IBM needs to be executed; need to identify process for this.

How has the community developed since the last report?    

    - First substantive design changes allowing for Service Provider Interfaces (SPIs) developed within Apache community (dev list, WIki, etc.).
    - Established bi-weekly Zoom "Technical Interchange" calls that have been well received.
        Complete videos posted to OW YouTube channel and detailed notes to our CWIKI.
    - Kubernetes on OpenWhisk work hosted a few ad-hoc to continue design discussions (CWIKI has designs and comments) 
      for how best to move away from Ansible deployments to self-configuring, autoscalable containers (for use in Kube, Mesos, Compose, etc.).
    - Increased interest/list/Slack traffic in general due to experiment Kube work, as it is applicable to Mesos, etc.
    - Increased community discussions (design topics, features) of substance moved to dev list.

How has the project developed since the last report?

    - incubator-openwhisk Github stars: 1928
    - incubator-openwhisk GitHub forks: 417
    - Movement to become more "pluggable" via Service Provider Interfaces (SPI), several PRs that are ongoing.
        - So far there are now interfaces for MessagingProvider.scala, ArtifactStoreProvider.scala 
          and proposals for others such as LogStore, ContainerFactory, LoadBalancer,

  Sig. PRs:

    - initial work on no root ansible #2669
        This allows to deploy with no sudo/root access. Significant to enable Kube/Mesos deployments.
    - Simplify Spi implementations. #2663
        Service Provider Interfaces (SPI) become more mature as patterns emerge.
        Healthy discussion/growth area for project to allow most components to become (eventually) pluggable 
        (e.g., Log, Trace, Container build, Load    Balancing, Scheduler, Routing, Message Queue, etc.)
    - Apply standard scala formatting #2650
        Coding/linting standards debated/agreed to by community (and CI automated enforcement encoded)
    - Allow multiple controllers and invokers in local environments #2633
        implement a ContainerPool which is completely independent of the underlying container driver to facilitate testing and extensibility.
        More improvements to allow different pooling of invoker containers based upon different application use case 
        (new ideas generated in community) including requirements for diff. scheduling/co-tenanting,/user responsiveness (http), etc. needs.

  Sig. discussions (dev list):

    - Release for OpenWhisk 
    - Releases and SPI plans
    - OpenWhisk shell tool
    - authentication models for openwhisk
    - Performance tests for OpenWhisk
    - Adaption of hosts-files
    - Default handling for HTTP web actions

How has the community developed since the last report?

In the summer of 2017, we took efforts to spread awareness about the
Quickstep project and technology. We had many talks, particularly in
the San Francisco Bay Area. The talks/venues are listed here:

  1.  SRI International in Menlo Park
  2.  A meetup hosted by H2O.ai in Mountain View
  3.  Hortonworks in Santa Clara (Thanks to our mentor Julian Hyde
      for hosting)

We had also applied for a talk at BigDataWisconsin meetup but the
proposal was not selected.
