  MRQL
  
  MRQL is a query processing and optimization system for large-scale,
- distributed data analysis, built on top of Apache Hadoop, Hama, Spark, and

  MRQL has been incubating since 2013-03-13.
  
  Three most important issues to address in the move towards graduation:
  
+   1. Increase the number of active committers
+   2. Increase adoption, expand user community, and increase user list activity

- Date of last release:
+ There were 8 JIRA issues reported during this period, from which 7
+ have already been resolved. The main work during this period was on
+ algebra-based and source-level debugging of MRQL queries. Basically,
+ results from an MRQL query are annotated with lineage information,
+ which links each result value with the input data that were used to
+ calculate the value. Given a result value, our debugger not only can
+ print the input values that contributed to the result value, but can
+ also display the detailed workflow that was used to calculate this
+ value (how-to provenance). In contrast other data-centric debuggers,
+ such as Titian for Spark, our debugger supports on-line browsing and
+ searching using GUIs and can work on all MRQL supported platforms
+ (map-reduce, Spark, Flink, and Hama). It also allows to insert trace
+ points in the query source to debug the query at the source level. We
+ hope that this debugger will be a valuable tool for developing and
+ understanding MRQL queries.
