◆ collectStatistics() [2/4]
| CollectStatisticsResponse & gpudb::GPUdb::collectStatistics | ( | const CollectStatisticsRequest & | request_, |

◆ collectStatistics() [3/4]
| CollectStatisticsResponse gpudb::GPUdb::collectStatistics | ( | const std::string & | tableName, |
| const std::vector< std::string > & | columnNames, | ||
| const std::map< std::string, std::string > & | options ) const |
Collect statistics for a column(s) in a specified table.
Parameters
| [in] | tableName | Name of a table, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table. A value of ’*’ collects statistics on every user table the caller may read (excluding system schemas, views, and temporary tables); when used, columnNames must be ’*’. |
| [in] | columnNames | List of one or more column names in tableName for which to collect statistics (cardinality, mean value, etc.). A single entry of ’*’ expands to every collectable column on the table (geometry, vector, JSON, and array columns are skipped). |
| [in] | options | Optional parameters. The default value is an empty map. |
Returns
Response object containing the result of the operation.
