Abstract: Apparatuses, systems, and methods that compare performance indications across platforms. In one embodiment, a method includes importing, by an processor, an audit trail of a host platform. The method includes executing, by the processor, instructions of a replay engine. The method includes executing, by the processor, instructions of a capture engine. The method includes executing, by the processor, instructions of an adaptation engine. The method includes exporting, by the processor, a configuration file to a target platform. The method includes comparing, by the processor, performance indications of the host and the target platforms.

Abstract: Methods and systems for processing a database query are disclosed. An example method includes receiving a SQL database query at a database query handling server, and parsing the SQL database query to identify a database and one or more tables and columns identified by the SQL database query. The method also includes determining a query plan based on the parsed database query. At a database engine, and based on the query plan and the identified database, tables and columns, the method further includes identifying a set of data nodes implicated by the identified database, tables and columns, determining a set of reduce operations and levels at which each of the set of map-reduce operations are to execute, and passing the query plan, the set of data nodes, and the map-reduce operations to a map-reduce query execution framework. The map-reduce query framework returns records as query results to the client system.
