Thank you for the response!

DESCRIBE table gives the column and datatype details and also the columns of PARTITION and CLUSTER. If cluster is used it mentions as Clustering Information and mention the columns used likewise for partition also.

So back to my previous question. Is there a way to Convert existing Delta Table with partition to a Delta Table with cluster.

1. Table A -- Partition column A

2. Take back up of Table A as A_bkp

3. Replace or Drop/Create Table A with Cluster Column B

4. INSERT TABLE A AS SELECT * FROM A_BKP

5. DROP A_BKP, remove the files associated

Is this a good approach?
