Leonidas Fegaras created MRQL-96: ------------------------------------ Summary: Develop a MRQL debugger Key: MRQL-96 URL: https://issues.apache.org/jira/browse/MRQL-96 Project: MRQL Issue Type: New Feature Components: Evaluation, Query Translation Affects Versions: 0.9.8 Reporter: Leonidas Fegaras Assignee: Leonidas Fegaras Priority: Minor
This patch introduces a novel query debugger based on the how-provenance information provided by the Provenance component addressed in MRQL-93. The debugger is a GUI based on JTree that allows to navigate through the provenance data associated with the query results in both forward and backward directions. The command to debug an MRQL query e is {{debug e}} for coarse-grain debugging or {{debug all e}} for fine-grain debugging. The GUI allows you to filter out the output or the input data to reduce the amount of information on screen. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
