getAggType

public String getAggType()

Get Aggregation type: When the table is an aggregation model (AGG_KEY), the column with the aggregation type is set as the metric column, and other columns are dimension columns. Aggregation type: ●SUM: sum; the values of multiple rows are accumulated. ●REPLACE: replacement; the values in the next batch of data will replace the values in the previously imported rows. ●MAX: retain the maximum value. ●MIN: retain the minimum value. ●REPLACE_IF_NOT_NULL: non-null values replacement. The difference from REPLACE is that null values are not replaced. ●HLL_UNION: aggregation method for HLL type columns, which is aggregated by HyperLogLog algorithm. ●BITMAP_UNION: aggregation method for BIMTAP type columns; bitmap union aggregation. Note: This field may return null, indicating that no valid values can be obtained.

Returns:
