ANALYZE_RTREE |
Analyzes an R-tree index; generates statistics about the index use, and recommends a rebuild of the index if a rebuild would improve query performance significantly. |
|
AVERAGE_MBR |
Calculates the average minimum bounding rectangle for geometries in a layer. |
|
ESTIMATE_INDEX_PERFORMANCE |
Estimates the spatial index selectivity. |
|
ESTIMATE_TILING_LEVEL |
Determines an appropriate tiling level for creating fixed-size index tiles. |
|
ESTIMATE_TILING_TIME |
Estimates the tiling time for a layer, in seconds. |
|
ESTIMATE_TOTAL_NUMTILES |
Estimates the total number of spatial tiles for a layer. |
|
EXTENT_OF |
Determines the minimum bounding rectangle of the data in a layer. |
|
HISTOGRAM_ANALYSIS |
Calculates statistical histograms for a spatial layer. |
|
MIX_INFO |
Calculates geometry type information for a spatial layer, such as the percentage of each geometry type. |
|
QUALITY_DEGRADATION |
Returns the quality degradation for an R-tree index or the average quality degradation for all index tables for an R-tree index. |
|
RTREE_QUALITY |
Returns the quality score for an R-tree index or the average quality score for all index tables for an R-tree index. |
