Hi,
With kafka you can increase overall throughput by increasing the number of
nodes in a cluster.
I had a similar issue, where we needed to ingest vast amounts of data to
streaming system.
In our case, kafka was a bottleneck, because of disk I/O. To solve it, we
implemented (simple) distributed
address this issue as well or
continue as it is?

Hi community,
Is there a way in Kafka Streams to change the order of operators in
runtime? For example, I have operators
Source->A->B->C->D->E->Sink
and I want to forward some tuples from A to E, from B to Sink and etc. As
far as I know, the stream execution graph is computed in compile time and

Hi community,
When using kafka-streams with POJO data types we write our own
de/serializers. However I think if we have built-in Serdes support for
Tuple-n data types (ex:Serdes.Tuple2) we may easily
use Tuples and built-in Serdes can help to reduce the development cycle.
Please correct me if I am

Currently, in kafka-streams we run the whole topology in one instance and

can be use-cases with very complex topologies with costly operators. So,
