Abstract
In a method for dynamic refresh of an index during query path generation for time series data, a query for time series data is received. During generation of a query plan based on the query, operations in a stage for a plurality of paths of execution are determined based at least in part on elements of the query, wherein execution of the stage comprises accessing an index of a plurality of indices. It is determined whether to refresh indices of a plurality of indices based on a potential usefulness of the indices in reducing a solution set for the stage of a path of execution of the plurality of paths of execution. The indices are selectively refreshed based on the potential usefulness of the indices in reducing a solution set for the stage of a path of execution of the plurality of paths of execution.
