Azure Synapse partition strategies

Question

Hello,

Can anyone help me with the below question:

From the azure synapse documentation, I can find that the "Dedicated SQL pool" tables can be partitioned using a value range (Range partitioning).
For Example: PARTITION ( [OrderDateKey] RANGE RIGHT FOR VALUES
(20000101,20010101,20020101
,20030101,20040101,20050101
)

I would like to understand, is Range-Partitioning is the only partitioning strategy supported by Azure-Synapse? or is there any other way of partitioning the Synapse table??

Hello @Vijay Sampath (Trianz) ,

Thanks for the question and using MS Q&A platform.

SQL Server and dedicated SQL pool support one partition column per table, which can be ranged partition.

PARTITION ( partition_column_name RANGE [ LEFT | RIGHT ] FOR VALUES ( [ boundary_value [,...n] ] ))  

Creates one or more table partitions. These partitions are horizontal table slices that allow you to apply operations to subsets of rows regardless of whether the table is stored as a heap, clustered index, or clustered columnstore index. Unlike the distribution column, table partitions don't determine the distribution where each row is stored. Instead, table partitions determine how the rows are grouped and stored within each distribution.

For more details, refer to Syntax differences from SQL Server and Table partition options.

Hope this will help. Please let us know if any further queries.
