Example 1 with StatisticsColumnData

use of org.apache.ignite.internal.processors.query.stat.messages.StatisticsColumnData in project ignite by apache.

the class StatisticsUtils method toMessage.

 * Convert ColumnStatistics to StaticColumnData message.
 *
 * @param stat Column statistics to convert.
 * @return Converted stats column data message.
 * @throws IgniteCheckedException In case of errors.
 */

Example 2 with StatisticsColumnData

use of org.apache.ignite.internal.processors.query.stat.messages.StatisticsColumnData in project ignite by apache.

 * @param keyMsg Statistics key.
 * @param type Statistics type.
 * @param stat Object statistics to convert.
 * @return Converted StatsObjectData message.
