Hi, everyone! We are supporting more 'group by' clauses in aggregation query for IoTDB which refers to some implements with new functions. So we want to ask for the advice of translated name in Chinese for these new features according to the functions and SQL of them.
1. Group By Variation Group-By-Variation wil set the first point in group as base point, then if the difference between a new point and base point is small than or equal to delta, this point will be put in the same group. (P.S. delta is the value users set and the difference is calculated by the expression users give). It can be described by the following picture: [image: groupByVariation.jpeg] Some alternative translation in Chinese: - 事件分段 - 差值分段 - Any suggestions 2. Group By Series Group-By-Series supports grouping the data points by the condition expression users give (the return type of condition expression needs to be boolean). The continuous data points which satisfy the condition expression will be put in the same group, the data points don't satisfy the condition will be skipped and won't be calculated by aggregation operator. Some alternative translation in Chinese: - 条件分段 - Any suggestions 3. Group By Session Group-By-Session will compute the difference between the value of time in continuous data points. A timeInterval is set by users to indicate the max gap of time in one group between continuous data points. It can be described in the following: [image: groupBySession.jpeg] The alternative translation in Chinese: - 会话分段 - 时间差值分段 - Any suggestions You can see more details and examples in https://iotdb.apache.org/UserGuide/Master/Query-Data/Group-By.html. Reply 1,2,3 to represent each groupByClause and add your advice, if you suggest "事件分段" for Group-By-Variation, you can reply > 1: "事件分段"
