Contains a row for each partition of all the tables and most types of indexes in the database. Special index types such as Full-Text, Spatial, and XML are not included in this view. All tables and indexes in [!INCLUDEssNoVersion] contain at least one partition, whether or not they are explicitly partitioned.
| Column name | Data type | Description |

| partition_id | bigint | Indicates the partition ID. Is unique within a database. |
| object_id | int | Indicates the ID of the object to which this partition belongs. Every table or view is composed of at least one partition. |
| 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 that contains the rows for this partition. |
| rows | bigint | Indicates the approximate number of rows in this partition. |
| filestream_filegroup_id | smallint | Applies to: [!INCLUDEssSQL11] through [!INCLUDEssCurrent]. Indicates the ID of the FILESTREAM filegroup stored on this partition. |
| data_compression | tinyint | Indicates the state of compression for each partition: 0 = NONE 1 = ROW 2 = PAGE 3 = COLUMNSTORE : Applies to: [!INCLUDEssSQL11] through [!INCLUDEssCurrent] 4 = COLUMNSTORE_ARCHIVE : Applies to: [!INCLUDEssSQL14] through [!INCLUDEssCurrent] Note: Full text indexes will be compressed in any edition of [!INCLUDEssNoVersion]. |
| 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. |
