2. Aiven's S3 sink connector - Support configure offset flush max size

   As Developer
   I want to use Aiven's S3 sink connector and have the ability to control the size of output files (keep same size even if the traffic changes). In general, the connector has no lags and we want to flush the offset and write to file only when we have enough data. We use offset.flush.interval.ms for it but when the traffic increases, the amount of data arrives in the configured interval is increased and can cause an OOM issue. In addition, when we pause the connector for couple of minutes and we gather a lag, it can also lead to OOM without temporary reducing the offset.flush.interval.ms.

4. Support for Protobuf serialization of Events (and Keys) in Aiven Kafka Connnect

   As a data engineer
   I want Aiven Kafka Connect to offer the option to use the protocol buffer data format when serializíng the events that is sends to a Kafka broker.
   In my specific case, I need it to be possible in a Debezium connector for PostgreSQL.
   Additionally, it would be good to have as a user the option to define oneself the protobuf schema to use for serializing.

6. Connectivity check for MirrorMaker with external Kafka integration

   Debugging failed connectivity between Aiven for Apache MirrorMaker and an external Kafka configured using an integration endpoint is very difficult today. No errors are surfaced in the integration endpoint configuration screen itself, we must wait for the replication flow to attempt to start and then dig out cryptic errors from MM2 logs.

   Some kinds of errors (e.g. failure to build SSL keystores) are not even surfaced in MM2 logs and are only visible to Aiven operators.

   Please consider adding a basic connectivity check to allow for quicker troubleshooting and iteration. This check should ensure that the network path between Aiven and the external Kafka is correct and the chosen authentication method and credentials are valid.

7. kafka_connect_connector_metrics availability over Prometheus

   Our customer Jago wants to monitor the status of connectors and tasks but currently can't find relevant metrics to do so. They want to be able to monitor the status of connectors and tasks on a dashboard and also get notified whenever a connector has not been running for X minutes.

   Jago has a connector running but can not find the metrics for kafka.connect:type=connector-metrics,connector=*.

   The specific metrics they are looking for is the one related to the status of a connector. For example, in the customers current self-managed kafka connect, they have the following metrics. This is convenient because they can get notified whenever a connector is not running.
   kafkaconnectconnector_metrics{status="running",connector="lfs-source-kafka-notifications",} 1.0

   They are also facing a similar issue with task status as they don't see metrics for it, while on their current cluster has:
   kafkaconnectconnector_status{connector="lfs-source-kafka-notification-created",status="running",task="0",} 1.0

   They have shared the attached metrics txt related to that connector that they got from prometheus.

   I want to be able to set the offset.flush.interval.ms only for my specific connector from the connector's configuration
   so that I can avoid configuring it in the cluster level (for all connectors).

    This function will largely be replaced by ChatGPT or other LLMs which can generate clear code and instructions, making a visual builder unnecessary. 

11. Event log should show when a connector is paused and resumed.

    As a developer
    I want to know when a connector is paused or resumed
    so that I can have timestamps and know if anybody is doing what they are not supposed to do.

12. Decompression transform for Connectors

    As an application developer
    I want to compress my kafka messages, but be able to decomrpess them using a transform before sinking them into a destination
    so that I can save on storage costs
    In addition, I'd like to use ZTSD, but more common libraries might be enough.

    Note, Confluent has something similar :

14. Move Karapace updates out of maintenance updates into IaC definitions

    As a customer
    I want to be able to select Karapace version updates in Terraform code instead of maintenance updates GUI
    so that I can control when Karapace updates are applied from my IaC definition.
    In addition, Karapace updates can introduce service interruptions for users because all consumer instances are terminated. Moving it out of maintenance updates means less user interruptions on often more important maintenance updates.

15. Include custom Kafka topic tags as Prometheus metric labels

    The Aiven platform allows custom key/value tags to be added to resources such as Kafka topics. It would be useful to have these exposed as additional labels on metrics so that alerts can be triggered based on this metadata.
