QUESTION
I am testing this function. The main bit for me is the call to add
method of a respository (partitionsOfATagTransactionRepository.add(transaction, infoToAdd,mutationCondition)
)
ANSWER
Answered 2020-Sep-02 at 08:00Mockito team made a decision to return default value for a method if no stubbing is provided.
See: https://javadoc.io/doc/org.mockito/mockito-core/latest/org/mockito/Mockito.html#stubbing
By default, for all methods that return a value, a mock will return either null, a primitive/primitive wrapper value, or an empty collection, as appropriate. For example 0 for an int/Integer and false for a boolean/Boolean.
This decision was made consciously: if you are focusing on a different aspect of behaviour of method under test, and the default value is good enough, you don't need to specify it.
Note that other mocking frameworks have taken opposite path - they raise an exception when unstubbed call is detected (for example: EasyMock).

Answered 2020-Mar-05 at 13:59In Kafka, committing does only make sense if you're part of a consumer group ( and then let Kafka cluster coordinators manage partition assignment and offset fetching/committing operations). Regarding your code, it looks like you're doing manual partition assignment, but still you're trying to commit:
QUESTION
Running Kafka Connect on a Kafka cluster which has auto creation of topics turned off. As far as I could see on another cluster that is working we had the topics connect-configs, connect-offsets, and connect-status created. So these topics were recreated on the new cluster with same replication factor and partitions.
We are getting an error when starting the service though I have netcat from connect instance to brokers and there was no connection issue there
...ANSWER
Answered 2020-Feb-19 at 14:07the topics were created manually,
Kafka Connect will use the AdminClient to initialize its own topics. There's no reason to do it manually.
If you do, you need to ensure the correct settings, which are documented in both Confluent and Apache Kafka documentation for getting started with Connect
QUESTION
Background
We have Apache Kafka managed by Zookeeper in our company. One of our Spring Boot applications needs to check the list of all topic available and also list which ones have log compaction enabled (cleanup.policy=compact).
Current Code
...ANSWER
Answered 2019-Jul-30 at 13:37You should use the AdminClient API to retrieve that information.
- First use
listTopics()
to retrieve the topic list. - Then use
describeConfigs()
to get the configuration for each topic. - Finally, out of the ConfigEntry objects you'll get, you can then filter the topics that have
compact
as thecleanup.policy
.
This is basically what the kafka-topics
tools is doing, so you can have a look at its source kafka.admin.TopicCommand
. Even though it's Scala, the concepts are similar.
QUESTION
I have started an instance of EmbeddedKafka in a JUnit test. I can read the records that I have pushed to my stream correctly in my application, but one thing I have noticed is that I only have one partition per topic. Can anyone explain why?
In my application I have the following:

Answered 2018-Nov-28 at 22:04You are connecting to Zookeeper (2181) instead of Kafka (9092 by default).
The Java kafka clients no longer talk directly to ZK.

In my one of the application I need to employ a Round Robbin key partitioning strategy on my kafka producer.
Writing to different partition works only with below settings (1):
...ANSWER
Answered 2019-Jul-08 at 14:32Since your records are key and value, default partitioner will check for key, if key is not there then only it will do normal partitioning otherwise hash will be calculated based on key.
Incase of key can not be removed for you records you can use the below partitioner code
QUESTION
I need to find the current partition key of a Service Fabric Stateful Service at run time.
I have looked in the ICodePackageActivationContext
and the StatefulServiceContext
but can't seem to see this information anywhere.
Edit:
As LoekD pointed out in his answer this information is available from within the StatefulService
class. Just to be explicitly clear, here is how I accessed:
ANSWER
Answered 2019-Jun-15 at 11:44From within the service itself, you can use the Partition.PartitionInfo
property.

QUESTION
How can we access the ParitionInfo object in a Controller class of a stateful service?
Here is the link to the object: https://docs.microsoft.com/en-us/dotnet/api/system.fabric.servicenotification.partitioninfo?view=azure-dotnet
...ANSWER
Answered 2018-Sep-08 at 08:48You're on the right path. Add an argument IStatefulServicePartition
to your MyConntroller
constructor.
In ConfigureServices
, register the service partition using this.Partition
.
