Abstract: Augmenting data files in a repository of an append-only file system includes maintaining a companion metadata file for each corresponding data file in a map-reduce system using the append-only file system. Each companion metadata file tracks a logical end-of-file (EOF) for each data file. Global versioning of each companion metadata is maintained. A map-reduce append job is performed for a set of data files using a current global version number for the companion metadata file. The map-reduce job including multiple append tasks. For each successful append job, a logical EOF for each appended file is incremented to a new physical EOF. For each failed append task of the append job, a logical EOF is maintained for each failed append task by not incrementing the logical EOF for each failed append task.

Abstract: Responding to relational database queries (for example, SQL queries) in a new way. More specifically, qualifying queries are written (for example, written by a human individual) in a way so that a join operation precedes a row limiting operation. Notwithstanding the fact that the join operation precedes the row limiting operation, when responding to the query, machine logic (for example, software) performs the row limiting operation before the join operation. This can improve time and processing efficiency.
