Tenzing A SQL Implementation On The MapReduce Framework

February 1, 2012 by Brent Sordyl 0 Comments

Tenzing is a query engine built on top of MapReduce for ad hoc analysis of Google data. Tenzing supports a mostly complete SQL implementation (with several extensions) combined with several key characteristics such as heterogeneity, high performance, scalability, reliability, metadata awareness, low latency, support for columnar storage and structured data, and easy extensibility. Tenzing is currently used internally at Google by 1000+ employees and serves 10000+ queries per day over 1.5 petabytes of compressed data. In this paper, we describe the architecture and implementation of Tenzing, and present benchmarks of typical analytical queries.

Migration of Relational Data structure to Cassandra (No SQL) Data structure

November 26, 2011 by Brent Sordyl 0 Comments

Cassandra data structures can be accessed using different programing languages like (.net, Java, Python, Ruby etc.). Data can be directly loaded from the relational databases (like Access, SQL Server, Oracle, MySQL, IBM DB2, etc.) using these programing languages. Custom loaders could be used to load data into Cassandra data structure(s) based on the enactment rules, customization level and the kind of data processing.

UnQL, pronounced “Uncle,” could be considered a “superset” of the SQL syntax, Phillips said. It can parse all statements formulated in the SQL language and supports a number of new operators and expressions as well.

NoSQL is a Premature Optimization

July 31, 2011 by Brent Sordyl 0 Comments

Point 1:  NoSQL technologies require more investment than Relational to get going with. 
Point 2:  There is no particular advantage to NoSQL until you reach scales that require it.  In fact it is the opposite, given Point 1.
Point 3:  If you are fortunate enough to need the scaling, you will have the time to migrate to NoSQL and it isn’t that expensive or painful to do so when the time comes.

neo4j – open source nosql Graph Database

June 7, 2011 by Brent Sordyl 0 Comments

Neo4j is a high-performance graph engine with all the features of a mature and robust database. The programmer works with an object-oriented, flexible network structure rather than with strict and static tables — yet enjoys all the benefits of a fully transactional, enterprise-strength database. For many applications, Neo4j offers performance improvements on the order of 1000x or more compared to relational DBs.
