CEP

[Mitz Leiner]

Hi!
I would like to apply CEP to built an autonomous model factory. I have
already found a lot on the documentation but still have some questions. It
would be great if some of you could help me with those:

- What components are distributed by the open source software? Is there a
way to perform complex event processing with apache storm, other than
adding an external cep engine like esper or drools to it?
- how well is Apache Storm scalable (horizontally)? how can you measure
scalability?
- how stable is the event throughput by adding more rules?
- What knowledge is needed to use Apache storm? How easy is it to maintain
the system once it is set up?
- How powerful is the EPL?
- What data formats are supported?
- How many times has Apache Storm been downloaded? Or do you have any
numbers available of how often it is used not only for ESP but also CEP?
- Are there any analytical  tools available? Is there a reporting system
which, e.g., exports analytic results as .pdf?
- How reliable are the results?

Many thanks in advance,

M

What about having a look at Heron? Afaik it was developed specifically 
to be run with an external scheduling component.

I had to rebuild some of the images for Storm to fix issues with

kubernetes as well.

Re: Containerising Storm

[Paritosh Anand]

Hi,

There is an official image for Apache Storm available on Docker hub. You
can start by trying this image.

If you may, you can also try this image
https://hub.docker.com/r/kakapari/docker-storm/ this simply installs

1. Zookeeper v3.4.8
2. Storm nimbus v0.10.1
3. Storm supervisor with 2 workers.

It is easier if you go through the Dockerfile for these repo and you might
find easy to write your own as well.

Re: Is LoadAwareShuffleGrouping The Default?

[Kevin Peek]

My apologies, the code I referenced above is old. I believe the correct
references are these:

https://github.com/apache/storm/blob/cd5c9e8f904205a6ca6eee9222ca954ca8b37ec3/storm-core/src/jvm/org/apache/storm/daemon/GrouperFactory.java#L63

https://github.com/apache/storm/blob/master/conf/defaults.yaml#L261

Based on these, I believe the LoadAwareShuffleGrouping is the default. Can
anyone more familiar with the code confirm this?

Containerising Storm

Is LoadAwareShuffleGrouping The Default?

[Kevin Peek]

Hello. I have a question about the load aware shuffle grouping.

If I create a grouping like below, will I end up with a
LoadAwareShuffleGrouping by default?

topologyBuilder.setBolt("boltId", new
SomeBolt()).shuffleGrouping("otherBoltId");

I would expect this to result in a traditional ShuffleGrouping, but I think
it does not based on the following:

(1) the config option TOPOLOGY-DISABLE-LOADAWARE-MESSAGING defaults to
false.
(2) This block of code seems to create a LoadAwareShuffleGrouping
automatically if load messaging is enabled (the default).
https://github.com/revans2/incubator-storm/blob/024ff263800e4032d7b2395fbbf072e0183ebb5b/storm-core/src/clj/backtype/storm/daemon/executor.clj#L66


Is this correct? Is load aware the default behavior in Storm 1.0.x?

Support of topic wildcards in Kafka spout

[Wijekoon, Manusha]

We have a topology that has multiple kafka spout tasks. Each spout task is 
supposed to read a subset of messages from a set of Kafka topics. Topics have 
to be subscribed using a wild card such as AAA.BBB.*. The expected behaviour 
would be that all spout tasks collectively will consume all messages in all of 
the topics that match the wild card. Each message is only routed to a single 
spout task (Ignore failure scenarios). Is this currently supported?
