You plan to create a dimension table in Azure Synapse Analytics that will be less than 1 GB.
You need to create the table to meet the following requirements:
✑ Provide the fastest query time.
✑ Minimize data movement during queries.
Which type of table should you use?

A. replicated

B. hash distributed

C. heap

D. round-robin








 

Suggested Answer: A

A replicated table has a full copy of the table accessible on each Compute node. Replicating a table removes the need to transfer data among Compute nodes before a join or aggregation. Since the table has multiple copies, replicated tables work best when the table size is less than 2 GB compressed. 2 GB is not a hard limit.
