Câu 26: Databricks Certified Data Engineer Professional

A data architect has designed a system in which two Structured Streaming jobs will concurrently write to a single bronze Delta table. Each job is subscribing to a different topic from an Apache Kafka source, but they will write data with the same schema. To keep the directory structure simple, a data engineer has decided to nest a checkpoint directory to be shared by both streams. The proposed directory structure is displayed below: Which statement describes whether this checkpoint directory structure is valid for the given scenario and why?

1. A. No; Delta Lake manages streaming checkpoints in the transaction log.
2. B. Yes; both of the streams can share a single checkpoint directory.
3. C. No; only one stream can write to a Delta Lake table.
4. D. Yes; Delta Lake supports infinite concurrent writers.
5. E. No; each of the streams needs to have its own checkpoint directory. — đáp án hiện tại
