|index_id||int||Indicates the ID of the index within the object to which this partition belongs.
0 = heap
1 = clustered index
2 or greater = nonclustered index
|partition_number||int||Is a 1-based partition number within the owning index or heap. For non-partitioned tables and indexes, the value of this column is 1.|
|hobt_id||bigint||Indicates the ID of the data heap or B-tree (HoBT) that contains the rows for this partition.|
|rows||bigint||Indicates the approximate number of rows in this partition.|
|filestream_filegroup_id||smallint||Applies to: SQL Server 2012 (11.x) and later.
Indicates the ID of the FILESTREAM filegroup stored on this partition.
|data_compression||tinyint||Indicates the state of compression for each partition:
0 = NONE

2 = PAGE
3 = COLUMNSTORE : Applies to: SQL Server 2012 (11.x) and later
4 = COLUMNSTORE_ARCHIVE : Applies to: SQL Server 2014 (12.x) and later
Note: Full text indexes will be compressed in any edition of SQL Server.
|data_compression_desc||nvarchar(60)||Indicates the state of compression for each partition. Possible values for rowstore tables are NONE, ROW, and PAGE. Possible values for columnstore tables are COLUMNSTORE and COLUMNSTORE_ARCHIVE.|
