Unable to reset partition offset with CooperativeStickyAssignor

I'm trying to reset offset to a partition to 0, like this:
final KafkaConsumer<String, String> stateConsumer = new KafkaConsumer<>(stateConsumerProperties.getConsumerProps());
stateConsumer.subscribe(STATE_TOPIC);
...
stateConsumer.seekToBeginning(stateConsumer.assignment());
...
stateConsumer.poll(Duration.ofMillis(1000)) // timeout too long, testing only
.forEach(record -> {
log.info("Warmup state read: " + record.value() + ", partition: " + record.partition());
stateMessages.add(record.value());
});
Consumer config is only this:
this.stateConsumerProperties.setConsumer(Map.of(
ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "kafka:9092",
ConsumerConfig.GROUP_ID_CONFIG, "state",
ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest",
ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringDeserializer",
ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringDeserializer",
ConsumerConfig.MAX_POLL_RECORDS_CONFIG, "30",
ConsumerConfig.FETCH_MAX_WAIT_MS_CONFIG, "2000",
ConsumerConfig.PARTITION_ASSIGNMENT_STRATEGY_CONFIG, CustomPartitionAssignor.class.getName()
));
The "custom" assignor is only for logging purposes, these are the only overrides:
public class CustomPartitionAssignor extends CooperativeStickyAssignor {
...
#Override
public GroupAssignment assign(Cluster metadata, GroupSubscription groupSubscription) {
return super.assign(metadata, groupSubscription);
}
#Override
public void onAssignment(Assignment assignment, ConsumerGroupMetadata metadata) {
super.onAssignment(assignment, metadata);
Arrays.toString(ASSIGNED_PARTITIONS.toArray()));
ASSIGNED_PARTITIONS = assignment.partitions();
log.info("New Assigned partitions: " + assignment.partitions());
}
...
}
I have only two identical consumers for testing and each consumer runs this code on join.
The first joiner has no issue since there is not state yet ("consumers" read another topic and produce "state" to state topic).
Problem is, this is what I get in the log when the second consumer joins:
consumer_2 | 2022-10-10 18:46:26.833 INFO 7 --- [pool-1-thread-1] o.a.k.c.c.internals.ConsumerCoordinator : [Consumer clientId=consumer-state-2, groupId=state] Setting offset for partition state-1 to the committed offset FetchPosition{offset=361, offsetEpoch=Optional[0], currentLeader=LeaderAndEpoch{leader=Optional[179bd3c6448e:9092 (id: 1001 rack: null)], epoch=0}}
consumer_2 | 2022-10-10 18:46:26.875 INFO 7 --- [pool-1-thread-1] c.company.fdi.poc.kafka.service.Consumer : Warmup state read: state 723, partition: 1

consumer_2 | 2022-10-10 18:46:26.876 INFO 7 --- [pool-1-thread-1] c.company.fdi.poc.kafka.service.Consumer : Warmup state read: state 727, partition: 1
State "production" is just an atomic counter that starts at 0.
What I want to happen is that when a new consumer joins, it resets its assigned partition offset to 0 and starts reading from the first record.
I have a suspicion that this has something to do with the CooperativeStickyAssignor, but I have no clue as of now.
You can assume 2 consumers, 2 partitions for state topic if this helps. Cluster should be as balanced as possible.
Start is two partitions one consumer, then I add another consumer.
Any help much appreciated, thanks in advance.

In kafka stream topology with 'exactly_once' processing guarantee, message lost on exception

I have a requirement where I need to process messages from Kafka without losing any message and also need to maintain the message order. Therefore, I used transactions and enabled 'exactly_once' processing guarantee in my Kafka streams topology. As I assume that the topology processing will be 'all or nothing', that the message offset is committed only after the last node successfully processed the message.
However in a failure scenario, for example when the database is down and the processor fails to store message and throws an exception. At this point, the topology dies as intended and is recreated automatically on rebalance. I assume that the topology should either re-consume the original message again from the Kafka topic OR on application restart, it should re-consume that original message from Kafka topic. However, it seems that original message disappears and is never consumed or processed after that topology died.
What do I need to do to reprocess the original message sent to Kafka topic? Or what Kafka configuration requires change? Do I need manually assign a state store and keep track of messages processed on a changelog topic?
Topology:
#Singleton
public class EventTopology extends Topology {
private final Deserializer<String> deserializer = Serdes.String().deserializer();
private final Serializer<String> serializer = Serdes.String().serializer();
private final EventLogMessageSerializer eventLogMessageSerializer;

private final EventLogProcessorSupplier eventLogProcessorSupplier;
#Inject
public EventTopology(EventsConfig eventsConfig,

EventLogProcessorSupplier eventLogProcessorSupplier) {
this.eventLogMessageSerializer = eventLogMessageSerializer;
this.eventLogMessageDeserializer = eventLogMessageDeserializer;
this.eventLogProcessorSupplier = eventLogProcessorSupplier;
init(eventsConfig);
}
private void init(EventsConfig eventsConfig) {
var topics = eventsConfig.getTopicConfig().getTopics();
String eventLog = topics.get("eventLog");
addSource("EventsLogSource", deserializer, eventLogMessageDeserializer, eventLog)
.addProcessor("EventLogProcessor", eventLogProcessorSupplier, "EventsLogSource");
}
}
Processor:
#Singleton
#Slf4j
public class EventLogProcessor implements Processor<String, EventLogMessage> {
private final EventLogService eventLogService;
private ProcessorContext context;
#Inject

}
#Override

}
#Override
public void process(String key, EventLogMessage value) {
log.info("Processing EventLogMessage={}", value);
try {
eventLogService.storeInDatabase(value);
context.commit();
} catch (Exception e) {
log.warn("Failed to process EventLogMessage={}", value, e);
throw e;
}
}
#Override
public void close() {

Feature: Feature covering the scenarios to process event log messages produced by external client.
Background:
Given event topology is healthy
Scenario: event log messages produced are successfully stored in the database
Given database is down
And the following event log messages are published
| deptId | userId | eventType | endDate | eventPayload_partner |
| dept-1 | user-1234 | CREATE | 2021-04-15T00:00:00Z | PARTNER-1 |
When database is up
And database is healthy
Then event log stored in the database as follows
| dept_id | user_id | event_type | end_date | event_payload |
| dept-1 | user-1234 | CREATE | 2021-04-15T00:00:00Z | {"partner":"PARTNER-1"} |

Do i need to close consumer here , i thought spring-kafka automatically take care those , if no could you please tell how to close in apring-kafka and also how to check if rebalance happened or not , because in DEBUG log not able to see any log related to rebalance.

I think your consumer may be rebalancing, because you are not calling consumer.close() at the end of your process.
This is a guess, but if the retention policy isn't kicking in (and the logs are not being deleted), this is the only reason I can tell for that behaviour.
Update:
As you set them as #KafkaListeners, you could just call stop() on the KafkaListenerEndpointRegistry: kafkaListenerEndpointRegistry.stop()

What causes a BAD Command Argument Error coming from exchange server?

I am writing a java program to iterate through all emails on an exchange server and move those to a folder. I am properly iterating through the emails and have found the attachment from the Multipart message, but when it comes to the point where I need to save the file. I am getting the error: "BAD Command Argument Error. 11". I have searched for the past few days and have not found what is causing this. What is causing this issue?
Here is my code:

As you can see I am finding the attachment (it has a filename and a filesize), but I cannot write to an output stream (I've tried to get the input stream and write to an output stream in every way possible and receive the same issue).
