Integration / Apache Pulsar Interview questions
What is Pulsar IO?
Pulsar IO is a connector framework, built on top of Pulsar Functions, that provides ready-made sources (to pull data into Pulsar from external systems) and sinks (to push data from Pulsar to external systems) without writing custom integration code.
Common connectors include sources/sinks for Kafka, JDBC databases, Elasticsearch, and cloud storage, each configurable declaratively rather than requiring a bespoke client application.
Because connectors run as managed Functions, they inherit the same deployment, scaling, and fault-tolerance handling, so operators manage data pipelines the same way they manage any other Pulsar Function.
