Zusammenfassung:A system includes a distributed file system to control storage of data across storage nodes and a database query engine to receive a database query for access of data, the database query engine to process the database query using an index, and using a buffer pool to cache data retrieved in response to the database query and to store updated data. An abstraction layer is provided between the database query engine and the distributed file system, the abstraction layer to read and write data of the distributed file system in response to the database query.
