Azure Event Hubs Flashcards
What is Azure Event Hub?
Azure Event Hubs is a cloud native data streaming service that can stream millions of events per second, with low latency, from any source to any destination. Event Hubs is compatible with Apache Kafka, and it enables you to run existing Kafka workloads without any code changes.
What are Partitions in Azure Event Hub?
Partitionsare used to scale an event hub. They are like lanes in a freeway. If you need more streaming throughput, you need to add more partitions.
What is Azure Schema Registry in Azure Event Hub?
Azure Schema Registry is a feature of Event Hubs, which provides a central repository for schemas for event-driven and messaging-centric applications. It provides the flexibility for your producer and consumer applications to exchange data without having to manage and share the schema.
What is Event Hubs Capture in Azure Event Hub?
Event Hubs Capture enables you to automatically capture the streaming data in Event Hubs and save it to your choice of either a Blob storage account, or an Azure Data Lake Storage account.
What is EventProcessorClient in Azure Event Hub?
Event processor clients can work cooperatively within the context of a consumer group for a given event hub. Clients will automatically manage distribution and balancing of work as instances become available or unavailable for the group.
What is Checkpointing in Azure Event Hub?
Checkpointing is a process by which an event processor marks or commits the position of the last successfully processed event within a partition. Marking a checkpoint is typically done within the function that processes the events and occurs on a per-partition basis within a consumer group.
