Abstract
A computer-implemented method for scan sharing across multiple cores in a business intelligence (BI) query. The method includes receiving a plurality of BI queries, storing a block of data in a first cache, scanning the block of data in the first cache against a first batch of queries on a first processor core, and scanning the block of data against a second batch of queries on a second processor core. The first cache is associated with a first processor core. The block of data includes a subset of data stored in an in-memory database (IMDB). The first batch of queries includes two or more of the BI queries. The second batch of queries includes one or more of the BI queries that are not included in the first batch of queries.
