Gordon,
Generally, having CQ on thin client would definitely be awesome. My only
point is that thin client has several technical limitations that would
introduce multiple "ifs" into the functionality. What exactly those ifs are,
and weather there is still value with all those ifs, is a big

Thanks Ilya,
We are writing to Ignite from Spark running in EMR. We don't know the

2) Leave localHost unset, and let ignite figure out the host

Hi Val,
It's a very simple, and I would say a very common use case. We want to send a
filter to the grid, receive a snapshot, and then receive a continuous stream of
updates that match that filter.
Consider a trading window, showing a grid of stocks. I want to subscribe to the

In my humble opinion there is a huge value here. We have these fantastic APIs
between our cluster nodes, why should we have to go and use different APIs, and
different serialization techniques in our end user apps? It’s totally
acceptable that the reliability, and guaranteed delivery aspects
Thanks Alexy, yes we have considered this approach. But I would normally
consider this type of architecture an optimization, not a base requirement.
It’s rather heavy and to me only makes sense when we have a large number of end
users and we want to minimize bandwidth to the remote locations.
Gaurav,
Web Console receives updates from web agent which periodically polls the

Igor,
I just think that we're dealing with a trade off here, and that if we
implement CQ for thin client, we will either end with a client that is not
"thin" anymore, or semantics and guarantees of CQ would change so
drastically that it would be a completely different feature. Either way,
it's a
Hi Val,
Ok, for smaller files inline is much cleaner, and that's what we prefer. But I
agree, for larger files its not such a good idea. Wew would really like to
avoid having configuration spread out all over the place.
Really, all we need to do is set the service name...we don't want to use

Hello Igniters,
We noticed that IgniteUtils class has a static initialization block (line
796 in version 2.6) in which System properties are being changed. In
particular, the property "http.strictPostRedirect" is set to "true".
This could change how an application behaves when referencing any

Hi,
Well, it depends on a lot of things - if you have small amount of the data,
which can easily fit in memory on each node, then, you can use Replicated
cache.
On the other hand, if you have quite big dataset, you may consider using
Partitioned cache and executing affinity runs.

1) It is.
2a) Ignite has retry mechanics for all messages, including PME-related ones.
2b) In this situation PME will hang, but it isn't a "deadlock".
3) Sorry, I didn't understand your question. If a node is down, but
DiscoverySpi doesn't detect it, it isn't PME-related problem.
4) How can you

Jeff,
The sessionAffinity is needed only if you plan to access Ignite cluster
deployed in K8 from an application deployed outside of it. For instance, it
will ensure that a remote JDBC session will stick to a specific Ignite pod.
However, if all your applications are deployed in K8 as well then

Yes if I remove session affinity it works. So my question is does ignite
require sessionAffinity? And to be honest, I'm not really sure what we are
using ignite for since it seems to be a multi-purpose app. I think we are
going to use for caching. So would session affinity be required for

Hi,
Do you really need to use Hive here? You can just use Spark integration
with Ignite, which allows to run sql: DataFrame(
https://apacheignite-fs.readme.io/docs/ignite-data-frame) or RDD(
https://apacheignite-fs.readme.io/docs/ignitecontext-igniterdd). For sure,
this solution will work much

How about to start several client nodes "near" to cluster and use them as

You may write some code that will push data from client node to you GUI app.
This will require some coding of course.
