wt_undirĪ working table holding an undirected version of the graph. If an empty name is specified, a new table will be generated, and its name will be returned. Cluster ID values are long integers that can have gaps between them. Column VID stores the vertex ID values, and column CLUSTER_ID stores the corresponding cluster ID values. This table has two columns (VID NUMBER, CLUSTER_ID NUMBER). wt_clustersĪ working table holding the final vertex cluster mappings. An optional string with one or more (comma-separated) of the following values: optionsĪdditional settings for operation. Name of the tablespace to hold the data stored in working tables. It must be an integer between 0 and num_sub_ptns*num_sub_ptns-1.ĭegree of parallelism for the operation. The logical subpartition to be used in triangle estimation (Only this partition will be counted). For a graph with a relatively small maximum degree, use the value 1 (the default). Must be a positive integer, power of 2 (1, 2, 4, 8. Number of logical subpartitions used in calculating triangles. wt_undAMĪ working table holding the undirected version of the graph data after applying the renumbering optimization. wt_rnmapĪ working table that is a mapping table for renumbering optimization. wt_undBMĪ working table holding an undirected version of the original graph (before renumbering optimization).

You must have the CREATE TABLE privilege to call this procedure. If TRUE, performs the operation even if one or more underlying tables are locked. If DBMS_STATS.AUTO_INVALIDATE (the usual default) is in effect, Oracle Database decides when to invalidate dependent cursors. If FALSE, invalidates the dependent cursors immediately. If TRUE, does not invalidate the dependent cursors. Use the constant DBMS_STATS.AUTO_CASCADE to have Oracle Database determine whether index statistics are to be collected or not. Gathers statistics on the indexes for the property graph schema tables. This is either 1 (serial execution) or DEFAULT_DEGREE (the system default value based on number of CPUs and initialization parameters) according to size of the object. The AUTO_DEGREE value determines the degree of parallelism automatically. Use the constant DBMS_STATS.DEFAULT_DEGREE to specify the default value based on the initialization parameters. The usual default for degree is NULL, which means use the table default value specified by the DEGREE clause in the CREATE TABLE or ALTER TABLE statement. The usual default is: FOR ALL COLUMNS SIZE AUTO degreeĭegree of parallelism for the property graph schema tables. SKEWONLY : Oracle Database determines the columns to collect histograms based on the data distribution of the columnsĬolumn is defined as column := column_name | (extension)Įxtension: Can be either a column group in the format of (column_name, column_name ) or an expression.
REPEAT : Collects histograms only on the columns that already have histograms.ĪUTO : Oracle Database determines the columns to collect histograms based on data distribution and the workload of the columns. Size_clause is defined as size_clause := SIZE This is the usual default.Īccepts either of the following options, or both in combination, for the internal property graph schema tables:įOR ALL COLUMNS įOR COLUMNS column|attribute. Use the constant DBMS_STATS.AUTO_SAMPLE_SIZE to have Oracle Database determine the appropriate sample size for good statistics. Percentage of rows to estimate in the schema tables (NULL means compute).
