With the Aggregate Data node, you are able to group the data according to the values in specific fields (grouping fields, database function group by) and can aggregate the data within this group into other field
从AggregatingMergeTree表中查询数据时,需使用GROUP BY子句并且要使用与插入时相同的聚合函数,但后缀要改为-Merge。 对于SELECT查询的结果,AggregateFunction类型的值对ClickHouse的所有输出格式都实现了特定的二进制表示法。在进行数据转储时,例如使用TabSeparated格式进行SELECT查询,那么这些转储数据也能直接用INSERT语句导回...
Aggregation provides different functions to control how data is aggregated, for example, to return the maximum, minimum, or average value. You can also group resource records by a specified set of attributes, known as grouping attributes, and aggregate the values of non-grouping attributes. The...

Put bounds on aggregated data To reduce the read dependency footprint of your query, you can partition your aggregate space and make sure you're using bounds whenever possible. Examples: // This query only reads scores between 95 and 100, so in a query it only reruns // when a score in...
