Subject [ANNOUNCE] MRQL: a new query language and system for Hadoop
Date Thu, 06 Oct 2011 22:18:02 GMT
Dear Hadoop users,

I apologize if this is not the right forum to post this announcement.  
If not, please direct me to the right forum.

I would like to announce the release of MRQL 0.5.2.

MRQL (the Map-Reduce Query Language) is an SQL-like query language for  
map-reduce computations, implemented on top of Hadoop. It is powerful  
enough to express most common data analysis tasks over many forms of  
raw data, such as XML and JSON documents, binary files, and line- 
oriented text documents with comma-separated values. It is more  
powerful than other current languages, such as Hive and Pig Latin,  
since it can operate on more complex data and supports more powerful  
query constructs, thus eliminating the need for using explicit map- 
reduce code.

Due to our limited resources, MRQL has only been tested on a small  
cluster (up to 8 nodes) and on Amazon Elastic MapReduce. Please let me  
know if you'd like to volunteer some of your time to test it on a  
larger scale.

You can find more information at the project web page:


Thank you,
