Examples with StatisticsColumnOverrides org.apache.ignite.internal.processors.query.stat.config.StatisticsColumnOverrides used on opensource projects

Example 1 with StatisticsColumnOverrides

use of org.apache.ignite.internal.processors.query.stat.config.StatisticsColumnOverrides in project ignite by apache.

the class SqlAnalyzeCommand method buildConfig.

/**
 * Build statistics object configuration from command arguments.
 *
 * @param target Statistics target.
 * @param params Map of parameter to value strings.
 * @return Statistics object configuration.
 * @throws IgniteSQLException In case of unexpected parameter.
 */

Example 2 with StatisticsColumnOverrides

use of org.apache.ignite.internal.processors.query.stat.config.StatisticsColumnOverrides in project ignite by apache.

 * @param params ANALYZE params to cut overrides from.
 * @return StatisticsColumnOverrides or {@code null} if there is no overriding parameters.
