Carlos,

I like to announce the work of the package renaming from whisk to 
org.apache.openwhisk for openwhisk main repository, asking folks to be aware of 
the change.

Re: towards the first apache release of openwhisk-composer

[Matt Rutkowski]

That is great news Dave!

Thanks for all your diligence in getting to this point. 

My only ask would be to update the table (README) in the release repo. 
https://github.com/apache/incubator-openwhisk-release
and the automation JSON: 
https://github.com/apache/incubator-openwhisk-release/blob/master/tools/config.json
to include an entry (with hash of commit) for this new repo.

In addition, I would appreciate it if you could follow the release 
process/steps there and open any issues you find with the exiting 
documentation (when following the manual process or auto. process),
i.e., "instructions for release managers (
https://github.com/apache/incubator-openwhisk-release/blob/master/docs/release_instructions.md
).

Of course, Vincent is the "go to" person for questions on docs/process

Cheers to you!

Subject:towards the first apache release of openwhisk-composer





Now that the formal donation process for the composer code base is
completed, we can start working towards the first formal release of
composer from the Apache OpenWhisk.

The motivation for a formal release is that we should have a formal Apache
release to enable us to publish an openwhisk-composer package to npm (to
replace the prior ibm-functions/composer npm package).

I'm willing to act as release manager for the initial release of this
package.

I believe the main technical work to be done before we can start preparing
a release candidate and then initiating the voting process is to agree on
the npm package name (suggestion: openwhisk-composer), and update the
documentation/code in the openwhisk-composer code base  accordingly.  Are
there any other items that I have overlooked?

Now that the formal donation process for the composer code base is
completed, we can start working towards the first formal release of
composer from the Apache OpenWhisk.

The motivation for a formal release is that we should have a formal Apache
release to enable us to publish an openwhisk-composer package to npm (to
replace the prior ibm-functions/composer npm package).

I'm willing to act as release manager for the initial release of this

Re: Relieve CouchDB on high load

[Markus Thömmes]

Hi Christian,

given the recent work towards getting logs to a separate store to relieve
CouchDB and to make it possible to move it into a store that's more
appropriate for logging load and some other bits that are already
implemented (removing the DB based polling, being able to disable log
collection), I think it makes sense to be able to disable activation
writing as well! In that sense, yes I do agree on going forward with the
proposal  + implementation.

One thing that has me worried a bit is the way we're handling global,
namespaced and per-action limits today. I'm wondering if at some point
we'll need to consolidate those and make them cascade reliably. For this
specific knob, for example, I think it would make sense to have one at the
system level and on the action/trigger level accordingly. For some of our
limits that might be true today already, I feel like it might not be for
all though (although I admittedly haven't double-checked).

Cheers,
Markus

Relieve CouchDB on high load

[Christian Bickel]

Hi developpers,

in some performance tests in the past we've seen, that there are the
following issues with Cloudant/CouchDB:
- not all activations can be stored (there are error logs in the invoker,
that storing was not possible)
- during bursts, CouchDB needs to process each document to update all views
in the activations-DB. If CouchDB is not able to process them immediately,
because of a queue, calling these views returns an error or the result will
be outdated (on calling them with stale). This has the impact, that there
is a delay for all users of the system until their activation appear after
calling `activation list`.

To not have negative impact of some high-load users on the system the
proposal is, to not store activations in activations-store for some
specified namespaces.
My proposal of an implementation is to put this flag into the
limits-document in subjects database.
This means, it can only be set by the administrator with wskadmin.

I already opened a PR with this proposal:
https://github.com/apache/incubator-openwhisk/pull/4078

Do you agree on going forward with this proposal and implementation?

Thanks a lot in advance for your feedback.

Greetings
Christian

Re: Tech Interchange call this Wed. Oct. 24 - add agenda topics here

[Michele Sciabarra]

I would like to show my new "actionloop" based Scala runtime!
Yes I know,  it is already possible to use Scala with the Java runtime.  But 
you have to compile, create a jar, include libraries
This one is based on the scripting shell "Ammonite" http://ammonite.io and 
works more like js and python.

Here is a  simple demo:

https://openwhisk.eu-de.bluemix.net/api/v1/web/sciabarra_cloud/scala/calc

And this is the source code:


import play.api.libs.json._
import scala.util.Try

def main(args: JsObject) : JsObject = {
val a = if(args \ "a" isDefined) {
Try(args("a").as[String].toInt).getOrElse(0)
} else 0
val b = if(args \ "b" isDefined) {
Try(args("b").as[String].toInt).getOrElse(0)
} else 0
if( args \ "add" isDefined) {
html(Some(s"${a} + ${b} = ${a+b}"))
} else if ( args \ "mul" isDefined) {
html(Some(s"${a} * ${b} = ${a*b}"))
} else html()
}

def html(msg: Option[String]=None) = {
val body = s"""
${if(msg.isEmpty) "" else ""+msg.get+""}

  
  
  +
  *
"""
Json.obj("body" -> body)
}


Deployed with this command:

wsk action update scala/calc calc.sc -m512 --web true --docker 
msciab/actionloop-scala-v2.12

The runtime is also part of a "collection" of runtimes based on the ActionLoop 
(the engine of the GoLang runtime) and I want to show how to build a new 
runtime for any language with just 3 files: a "compiler" script, a launcher and 
a Dockerfile.

I already did the runtimes for Swift and Scala, and I have in mind many others 
(rust, haskell and kotlin  for example).
