While defining a new table which uses liquid cluster, we mention at the end as 'USING DELTA CLUSTER BY (Column1)'

As per above solution Point 3 Cluster by the new column, its mentioned as 

.partitionBy("colB")

How is it identified as CLUSTER? Because while creating a table we have CLUSTER BY and PARTITION BY as 2 different usage and that's how table is identified as CLUSTER or PARTITION. 

As per above explanation , does the DESCRIBE table show it as cluster?
