You have an Azure Synapse Analytics dedicated SQL pool named Pool1 and a database named DB1. DB1 contains a fact table named Table. You need to identify the extent of the data skew in Table1. What should you do in Synapse Studio?
A.
Connect to Pool1 and query sys.dm_pdw_nodes_db_partition_stats.
B.
Connect to the built-in pool and run DBCC CHECKALLOC.
C.
Connect to Pool1 and run DBCC CHECKALLOC.
D.
Connect to the built-in pool and query sys.dm_pdw_nodes_db_partition_stats.
The answer is ok. tou runt the dmv over the database, no in the SQL Pool.
To call this from Azure Synapse Analytics or Analytics Platform System (PDW), use the name sys.dm_pdw_nodes_db_partition_stats. The partition_id in sys.dm_pdw_nodes_db_partition_stats differs from the partition_id in the sys.partitions catalog view for Azure Synapse Analytics. This syntax is not supported by serverless SQL pool in Azure Synapse
