Abstract
A method includes receiving a query directed to a bitmap index. The bitmap index includes a plurality of bit strings, where a value stored in a particular location in each of the bit strings indicates whether a corresponding signal associated with a signal source has been received, and where the bitmap index includes at least a first metadata value associated with each of the bit strings, at least a second metadata value associated with each of a plurality of signal sources, or both. The method also includes generating a query execution plan for the query and generating query results based on the query execution plan. The query results identify at least one signal associated with at least one bit string of the plurality of bit strings, at least one signal source of the plurality of signal sources, and at least one of the first metadata value or the second metadata value.
