Abstract: Techniques for improving efficiency of data processing associated with data queries are described. For example, a computer system may access a first query result of a first time window that result may have been generated based on first transformed data stored in data partitions associated with the first time window. The computer system may access data corresponding to a time unit that falls outside of the first time window and inside a second time window. The first time window and the second time window may have overlapping time units. The computer system may generate a data partition that corresponds to the time unit and that stores second transformed data. The second transformed data may correspond to a data transformation of the data. The computer system may generate a second query result for the second time window based on the second transformed data and the first query result.
