Abstract
Storage-side filtering may be implemented for performing hash join operations with respect to data stored in distributed data storage. When a query to a database stored in a distributed data store is received, a hash join operation may be identified for performing the query. As part of performing the hash join operation, a query engine may cause storage nodes in the distributed data storing data for the database to filter data before sending the data to the query engine according to a join predicate for the hash join operation. A result of the query may then be provided to a user, using the filtered data provided from the storage nodes.
