DECLARATIVE MAPREDUCE USING REGULAR EXPRESSIONS

摘要

A system and method for facilitating extracting processing data, in a networked computing environment. An example method includes receiving a signal from a user input device specifying a regular expression. The regular expression includes criteria for extracting data from a database or file, e.g., a text, XML, JSON, or other type of file. A selected function is applied to data that is extracted in accordance with the regular expression via a MapReduce framework. In a more specific embodiment, the method further includes delivering reduced or processed data to a DataBase Management System (DBMS) of a networked enterprise computing environment. The database includes a file with data obtained from one or more databases distributed among one or more servers of the enterprise computing environment.

1. A method for facilitating extracting and processing data in a computing environment, the computing environment including one or more servers in communication with one or more client devices, wherein the one or more client devices execute a software, the software executing steps of the method, the method comprising:
receiving from a user input device a regular expression, wherein the regular expression includes one or more criteria for extracting data from a database; determining a function to apply to data be extracted in accordance with the regular expression; providing the regular expression and the function to a MapReduce framework as part of a specification of a MapReduce job; and receiving data matching the criteria and processed in accordance with the function.
