A data engineer executes the following query: spark . readStream . format ( 'delta' ) . table ( 'scorecard' ) . writeStream . option ( 'checkpointLocation' , '/tmp/scores' ) . format ( 'delta' ) . option ( 'mergeSchema' , 'true' ) . table ( 'performance' ) What will be the result of the query and the performance table if a column from the scorecard table is renamed while the query is running?
