Yes, with the self-hosted Airbyte application, you can perform more frequent incremental syncs. Although the sync frequency in the UI can be set as low as five minutes, you can trigger Airbyte syncs more frequently using the API or integrating it with a workflow management tool like [Airflow](https://airbyte.com/blog/airflow-etl-pipelines), [Prefect](https://airbyte.com/recipes/elt-pipeline-prefect-airbyte-dbt), or [Dagster](https://airbyte.com/recipes/orchestrate-data-ingestion-and-transformation-pipelines) [source](https://airbyte.com/tutorials/real-time-data-analytics-pipeline). Regarding syncing from a Kafka source, Airbyte can sync data from Kafka to a database destination. Each stream is written to the corresponding Kafka topic [source](https://docs.airbyte.com/integrations/destinations/kafka). However, the sync frequency still applies, and you would need to configure the sync mode and frequency according to your requirements. You can also trigger manual syncs from the Airbyte UI or use the API for more control over the sync process [source](https://airbyte.com/tutorials/mysql-cdc-to-kafka). Keep in mind that Airbyte's incremental synchronization is designed to efficiently keep a source and a destination in sync by replicating only the changes that have occurred since the previous sync [source](https://airbyte.com/tutorials/incremental-data-synchronization).
