Implement a stream-static join where the static dataset is a large reference table and the streaming dataset is continuously updated. Describe how you would ensure that the join operation is efficient and handles schema evolution. Include the use of broadcast joins and schema enforcement.
A
Perform a full table scan join without using broadcast joins or schema enforcement.
B
Use a broadcast join to optimize the join operation and enforce schema using Delta Lake to handle schema evolution.
C
Ignore schema evolution and directly perform the join operation.
D
Use a batch query to avoid dealing with streaming data.
