Answer: Each microbatch of a stream-static join will use the most recent version of the static Delta table as of the job's initialization.
In stream-static joins, the static Delta table is read once at the start of the streaming job. Each microbatch in the stream will use the version of the static table available at job initialization, even if the static table is updated later. This makes option B the correct answer. Options A and C are incorrect because checkpoint directories are not used to track updates to the static Delta table or state information for the unique keys present in the join. Option D is incorrect because stream-static joins can indeed use static Delta tables without consistency issues.
