An aggregate is generated. Upon receiving a second query comprising a filter criterion, a determination is made as to whether at least a threshold number of previous first queries comprises a similar filter criterion, and if so generating an aggregate using the similar filter criterion as an aggregation criterion, such that future queries comprising the similar filter criterion are satisfied by the aggregate.

Demand-driven dynamic aggregate

A capability for updating a cache. The capability includes identifying, in a query instance that has led to a filling of the cache, a parameter whose values are monotonic&#x2014;in particular monotonically increasing or decreasing&#x2014;over time, wherein the query instance has a first execution time. When generating a new query instance, at a second, later execution time instead of the previous value of the parameter, a new value may be used that corresponds to the monotonic previous value at the second execution time. The new query instance is executed, wherein the cache is updated with the results of the new query instance.
