BigData / Apache StreamPark Interview questions

How does StreamPark integrate with Apache Paimon for streaming warehouses?

StreamPark positions itself as more than a job runner — its stated goals include building a real-time data warehouse and unified stream/batch data solution, and Apache Paimon is one of the ecosystem tools it's built to integrate with toward that end.

In practice, this integration works through the same connector and Flink SQL paths StreamPark already offers: a Flink SQL job can declare Paimon as a source or sink table, letting StreamPark-managed jobs read from and write to Paimon's lake-format tables as part of a streaming pipeline. Combined with StreamPark's Catalog support, this lets a team define and reuse Paimon table metadata across multiple jobs rather than redeclaring schemas job by job.

This is what lets StreamPark support "streaming warehouse" and OLAP-style scenarios — not by replacing Paimon's own engine, but by orchestrating the Flink jobs that read and write into it.

How does a StreamPark job typically read from or write to Apache Paimon?
