2018-06-19 09:57:26 UTC - Harald Gustafsson: I wanted to check if the python 3 
pulsar clients for mac is also in the process of publishing to pypi.
----
2018-06-19 16:06:23 UTC - Karthik Palanivelu: Team, I have a quick question - 
If I start a proxy will by itself start a broker? because I start a broker and 
start a proxy on K8s. Is this a right order?
----
2018-06-19 17:05:27 UTC - Ali Ahmed: @Harald Gustafsson Maybe not for 2.0.1 but 
2.1 is getting close we will add python3 osx modules to it.
----
2018-06-19 17:05:50 UTC - Ali Ahmed: @Karthikeyan Palanivelu proxy does not 
start a broker by itself
----
2018-06-19 17:06:18 UTC - Matteo Merli: @Harald Gustafsson builds for macos and 
py3 are coming now with 2.0.1. just not uploaded yet to pypi
----
2018-06-19 17:06:20 UTC - Ali Ahmed: ideally brokers should be like and then 
then the proxy should start.
----
2018-06-19 17:08:29 UTC - Karthik Palanivelu: Cool then I am doing right 
starting brokers and then proxy. Can you please look into my error I posted 
above from Proxy or I copied below?

2018-06-19 17:10:11 UTC - Ali Ahmed: @Karthikeyan Palanivelu check the 
kubernetes logs for proxy and brokers , to see if any connection errors are 
happening
----
2018-06-19 17:11:34 UTC - Harald Gustafsson: @Matteo Merli thanks, need the new 
simplified auth
----
2018-06-19 17:18:38 UTC - Karthik Palanivelu: @Ali Ahmed I see only below log 
in proxy:
```
21:07:03.181 [pulsar-discovery-io-2-2] INFO  
org.apache.pulsar.proxy.server.ProxyConnection - [/XX.XX.XX.XX:30989] New

And only exception in broker logs is:

 and commented: broker.log - All brokers has this exception
----
2018-06-19 17:26:56 UTC - Ali Ahmed: don’t know the reason for the error , did 
you try to send a message with a very large payload ?
----
2018-06-19 17:27:48 UTC - Karthik Palanivelu: This was happening when I start 
the Listener/Consumer...
----
2018-06-19 17:29:10 UTC - Ali Ahmed: I don’t know right now will have to spend 
some later , can you try your cluster without encryption and see if that works?
----
2018-06-19 19:04:14 UTC - Ivan Kelly: @Karthikeyan Palanivelu that error is 
trying to send a http request to a binary protocol endpoint

2018-06-19 19:40:53 UTC - Harald Gustafsson: Oh, I see now that the 
AuthenticationTLS is commited after 2.0.1. How is the Authentication class used 
that exist in 2.0.1
----
2018-06-19 19:41:19 UTC - Matteo Merli: Yes, I was double checking here
----
2018-06-19 19:41:39 UTC - Matteo Merli: the part about auth was to be included 
in 2.1
----
2018-06-19 19:42:27 UTC - Matteo Merli: we just backported the packaging fixes 
for 2.0.1
----
2018-06-19 19:46:41 UTC - Matteo Merli: btw, @Harald Gustafsson the macos 10.13 
build for py3 is available, though without the auth-tls changes as above
----
2018-06-19 19:52:35 UTC - Harald Gustafsson: @Matteo Merli OK, I will need to 
figure out how to use the current method then, I thought I had seen some 
example of that. I wonder how to get the path to the lib.
----
2018-06-19 19:58:48 UTC - Matteo Merli: Main problem, (which the fix in 2.1 is 
trying to solve) is that the plugin system is expecting the `tls.so` lib 
somewhere. Unfortunaly, the `tls.so` cannot be included in the python wheel 
file. 

You would have to compile C++ library and copy `tls.so` and use 
`pulsar.Authentication()` class. For parameters, it would be similar to the 
example here: 
<http://pulsar.apache.org/docs/v2.0.1-incubating/clients/Cpp/#Authentication-h6s57i>
----
2018-06-19 19:58:52 UTC - Matteo Merli: (for c++)
----
2018-06-19 20:49:40 UTC - Harald Gustafsson: @Matteo Merli I tried the homebrew 
install of the C++ was hoping that the tls.so would be found from that but 
could not find it. The homebrew actually builds 2.1 snapshot. Would it be 
possible to generate the python package for 2.1 instead, from source? Anyway 
need to give up for today.
----
2018-06-19 20:55:04 UTC - Ali Ahmed: yes the python packages can be generated 
from source
----
2018-06-19 21:21:16 UTC - Matteo Merli: @Harald Gustafsson there’s a script to 
generate all combination of Python builds: 
`./pulsar-client-cpp/docker/build-wheels.sh`. It builds the code from the 
current working dir and leaves the `whl` for each Python version

2018-06-20 08:07:57 UTC - Idan: Hi guys, some of our consumers using batching 
model. one of the reasons we use batching is because we want to insert in batch 
to datasources like RDS. on pulsar you can enable batching but the API still 
consume the messages as individual. any code examples how to wrap this with 
internal queue to let our consumers get this in a list (or aggregated) some how
----
2018-06-20 08:17:48 UTC - Ali Ahmed: @Idan consumer batching is already done
----
2018-06-20 08:24:06 UTC - Sijie Guo: @Idan a couple of ideas:

1) if you are using MessageListener, you can create a queue in your message 
listener implementation, when receiving a message from message listener, you 
put the item into the queue and check if the queue reaches a given size, if so, 
then return this list of messages to your application, so your application can 
insert them in batch to RDS.

2) if you are using receiveAsync, you could create a 
List&lt;CompletableFuture&lt;Message&gt;&gt; futures.

then 

```
for (int i = 0; i &lt; batchSize; i++) {
    futures.add(consumer.receiveAsyc());
}

List&lt;Message&gt; messages = 
CompletableFuture.allOf(futures.toArray()).thenApply(result -&gt; 
futureList.stream.map(CompletableFuture::join).collect(Collectors.toList()));

```


then you can return them as a list of messages.


however in both 1) and 2), you need some logic to handle if there is no message 
coming in within a given time period.

3) ideally, this batch interface should exist in pulsar indeed. since 
internally messages are batched to store to storage and transfer over network. 
so pulsar has all the information, so it can just return the whole batch as a 
message iterator, which you can then iterate over messages.
----
2018-06-20 08:33:02 UTC - Idan: iam recievieing the messages using this: recieve

2018-06-20 09:03:21 UTC - Harald Gustafsson: @Matteo Merli The wheel building 
did not work. I'm building on a mac so the mounted volume is from a mac, which 
have not been a problem before but maybe this time. First of on a fresh git the 
scripts is trying to remove CMake* files and fails since not existing. That was 
easily fixed by creating some empty files. But when building the wheels with 
`./pulsar-client-cpp/docker/build-wheels.sh`I get the following error:
