When I call addData() in streamer. this data will send & buffer in server
node. is that correct?
If I correct, this data will buffer in random server node or only the one
it directly connected?

This is positive news Andrey. Thanks a lot.
Please keep us posted about reproducing this. We are definitely not using
node filters...and we suspect topology changes to be causing issues, but
irrespective of that, we are not able to reproduce it. we also do not see

I've reproduced the problem and have exatly the same stack traces for

But my case looks too complex. I started three nodes and cache1 on

I believe it will be kept unless the cache is explicitly destroyed.
Kind regards,

Thank you. Last question -
Why it showing up with 1.9 and not earlier?
Thanks,

It looks like it's working now. I think it was a proxy issue.

This is using Ignite 1.9. The stack trace is pretty straight forward:

1. Ignite receives data via Kafka Streamer
2. Tuple Extractor is implemented in ignite code
Everything works fine till this step.
3. We stop kafka. No error yet.

5. Kafka Consumer remapping also happens without any

Hi Alexei,
Tests for Cassandra module should be executed just using standard maven
approach: mvn clean test

Please attach stack trace, and what version of Ignite do you use?

Hi,
How many backups (o.a.i.configuration.CacheConfiguration#setBackups) do you
use?
If your cluster does not contain backups, a batch will not remaped, until
rebalance finished.

Hi Rishi,
This means your node found another node with different
'java.net.preferIPv4Stack'
value.
Please, check if there is no other node running?

It may have effect if you prepare data for streamer (call addData) slowly
and it is possible to utilize more resources for it. Of course remote nodes
should be able to bear pressure of data.
Performance can increased, but usually slightly as network will be a
bottleneck.

Hi,
There are number of methods with confising names. Actually, gridName means
ignite instance name. It will be fixed in 2.0 release.
1. Ignition.allGrids() return local JVM node instances. If you need all
cluster nodes, see Ignite.cluster() method.
2. Both of you nodes belongs to same cluster a
Hi,
I'm a bit confused about the purpose of the Ignition.allGrids() method, and
how also the naming of grids using the IgniteConfiguration works.
I started a node using Ignition.getOrStart() with an IgniteConfiguration
with name set to grid1, then create a cache and add some values to it. I

Is that mean the performance of input data will not affect if I use 2
IgniteDataStreamer(2
client program) to input data as they use the same queue in remote nodes?

Hi!
You may try to use
1) https://apacheignite.readme.io/docs/rest-api#cache-metadata
2) org.apache.ignite.internal.visor.cache.VisorCacheMetadataTask (or see
how it is implemented).
But, PLEASE NOTE, this is internal API and may be changed in future
versions of Ignite.

1. So considering example from post 1, does it mean that when an ignite
instance was killed, Data streamer had some data which it was going to put
in to cache but that cache's instance was killed and hence the error might
have occurred.
2. If not, than can you throw some light on the remap error fr
Hi Sam,
Ignite use messages for inter-node communication.
You have to configure TcpCommunicationSPI in IgniteConfiguretion. Method
TcpCommunicationSPI.setMessageQueueLimit() is what you need.

What do you mean by messages? I am not using Ignite messaging. Are these
