  Column	Datatype	NULL	Description
  INDEX_OWNER	VARCHAR2(30)		Owner of the index
  INDEX_NAME	VARCHAR2(30)		Name of the index
  COMPOSITE	VARCHAR2(3)		Whether the partition belongs to a local index on a composite-partitioned table (YES | 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 partition
  COMPRESSION	VARCHAR2(8)		Indicates whether key compression is ENABLED or DISABLED for a partitioned index. 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 command
  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)		The actual buffer pool for the partition
  USER_STATS	VARCHAR2(3)		Whether the statistics were entered directly by the user (YES | 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).
