Abstract: A method, apparatus, and system for join operations of a plurality of relations that are distributed over a plurality of storage locations over a network of computing components. An example method includes: receiving a relational join query for a join operation associated with a first relation and a second relation; generating at least one build operator and at least one probe operator to perform build operations and probe operations, respectively, of the join operation; and managing a state of one or more communication links between the at least one build operator and the at least one probe operator based on a size of the second relation as determined by the at least one build operator and an estimated size of the first relation.

Abstract: A system, apparatus, and method for processing queries wherein the query includes a request to access or delete data and accessing metadata associated with the set of data, the metadata defining data characteristics of the set of data and identifying at least sets of data that need or not need to be accessed or deleted based on the metadata without accessing the actual data in the set of data; also methods to optimize processing of some operations based on the collected metadata on data.

Abstract: A query directed to database data stored across a set of files is received. The query includes predicates applied against metadata of the set of files. One or more files are removed from the set of files whose metadata does not satisfy a predicate of the plurality of predicates. Rows of the one or more remaining files of the set of files are filtered based on the one or more predicates.
