Column	Datatype	Description
`INDEX_OWNER`	`VARCHAR2(30)`	Owner of the index
`INDEX_NAME`	`VARCHAR2(30)`	Name of the index
`COMPOSITE`	`VARCHAR2(3)`	Indicates whether the partition belongs to a local index on a composite-partitioned table (`YES`) or not (`NO`)
`PARTITION_NAME`	`VARCHAR2(30)`	Name of the partition
`SUBPARTITION_COUNT`	`NUMBER`	If a local index on a composite-partitioned table, the number of subpartitions in the partition
`HIGH_VALUE`	`LONG`	Partition bound value expression
`HIGH_VALUE_LENGTH`	`NUMBER`	Length of partition bound value expression
`PARTITION_POSITION`	`NUMBER`	Position of the partition within the index
`STATUS`	`VARCHAR2(8)`	Whether index partition is `USABLE` or `UNUSABLE`
`TABLESPACE_NAME`	`VARCHAR2(30)`	Name of the tablespace containing the partition
`PCT_FREE`	`NUMBER`	Minimum percentage of free space in a block
`INI_TRANS`	`NUMBER`	Initial number of transactions
`MAX_TRANS`	`NUMBER`	Maximum number of transactions
`INITIAL_EXTENT`	`NUMBER`	Size of the initial extent in bytes
`NEXT_EXTENT`	`NUMBER`	Size of secondary extents in bytes
`MIN_EXTENT`	`NUMBER`	Minimum number of extents allowed in the segment
`MAX_EXTENT`	`NUMBER`	Maximum number of extents allowed in the segment
`PCT_INCREASE`	`NUMBER`	Percentage increase in extent size
`FREELISTS`	`NUMBER`	Number of process freelists allocated in this segment
`FREELIST_GROUPS`	`NUMBER`	Number of process freelist groups allocated in this segment
`LOGGING`	`VARCHAR2(7)`	Logging attribute of the partition
`COMPRESSION`	`VARCHAR2(8)`	Indicates whether key compression is enabled for a partitioned index (`ENABLED`) or not (`DISABLED`); null for a nonpartitioned index.
`BLEVEL`	`NUMBER`	B*-Tree level: depth of the index from its root block to its leaf blocks. A depth of `0` indicates that the root block and leaf block are the same.
`LEAF_BLOCKS`	`NUMBER`	Number of leaf blocks in the index partition
`DISTINCT_KEYS`	`NUMBER`	Number of distinct keys in the index partition
`AVG_LEAF_BLOCKS_PER_KEY`	`NUMBER`	Average number of leaf blocks in which each distinct value in the index appears, rounded to the nearest integer. For indexes that enforce `UNIQUE` and `PRIMARY KEY` constraints, this value is always `1`.
`AVG_DATA_BLOCKS_PER_KEY`	`NUMBER`	Average number of data blocks in the table that are pointed to by a distinct value in the index rounded to the nearest integer. This statistic is the average number of data blocks that contain rows that contain a given value for the indexed columns.
`CLUSTERING_FACTOR`	`NUMBER`	Indicates the amount of order of the rows in the table based on the values of the index. If the value is near the number of blocks, then the table is very well ordered. In this case, the index entries in a single leaf block tend to point to rows in the same data blocks. If the value is near the number of rows, then the table is very randomly ordered. In this case, it is unlikely that index entries in the same leaf block point to rows in the same data blocks.
`NUM_ROWS`	`NUMBER`	Number of rows returned by the `ANALYZE` statement
`SAMPLE_SIZE`	`NUMBER`	Sample size used in analyzing this partition
`LAST_ANALYZED`	`DATE`	Date on which this partition was most recently analyzed
`BUFFER_POOL`	`VARCHAR2(7)`	Actual buffer pool for the partition
`USER_STATS`	`VARCHAR2(3)`	Indicates whether statistics were entered directly by the user (`YES`) or not (`NO`)
`PCT_DIRECT_ACCESS`	`NUMBER`	If a secondary index on index-organized table, the percentage of rows with `VALID` guess
`GLOBAL_STATS`	`VARCHAR2(3)`	Indicates whether statistics for the partition were collected for the partition as a whole (`YES`) or were estimated from statistics on underlying subpartitions (`NO`)
`DOMIDX_OPSTATUS`	`VARCHAR2(6)`
`PARAMETERS`	`VARCHAR2(1000)`
