<string>&lt;html&gt;&lt;head/&gt;&lt;body&gt;&lt;p&gt;When the layer is setup various metadata is required for the Oracle table. This includes information such as the table row count, geometry type and spatial extents of the data in the geometry column. If the table contains a large number of rows determining this metadata is time consuming.&lt;/p&gt;&lt;p&gt;By activating this option the following fast table metadata operations are done:&lt;/p&gt;&lt;p&gt;1) Row count is determined from all_tables.num_rows.&lt;/p&gt;&lt;p&gt;2) Table extents are always determined with the SDO_TUNE.EXTENTS_OF function even if a layer filter is applied.&lt;/p&gt;&lt;p&gt;3) The table geometry is determined from the first 100 non-null geometry rows in the table.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</string>
