BigSQL Up and Running

BigSQL Up and Running All Big Data projects are a collection of related projects, each suited to a specific function to implement that Big Data solution. BigSQL can be used as a Big Data Data Warehousing solution. In addition to the archetypical Big Data components (Hadoop Distributed File System and MapReduce), there are additional projects [...]

PostgreSQL Clustering with Postgres HA

PostgreSQL Clustering made easy with PostgresHA. Authored jointly with Scott Mead, Sr. Architect OpenSCG and Architect of PostgresHA. PostgresHA is Highly Available (HA) PostgreSQL. High Availability High availability is not new. Financial trading systems and the telephone network were federally mandated to provide highly availability. People didn’t do HA because it was a fun project, [...]

The Hadoop Ecosystem

The Hadoop Ecosystem. Big Data is more than just the Apache Hadoop kernel; it is a collection of related projects. Some of them are mandatory (you cannot do Big Data without them) and others are optional (like data loaders and flow processing languages). The mandatory Hadoop projects are HDFS, MapReduce and Common.  Common is a [...]

HDFS

HDFS, The Hadoop Distributed File System. When you Map a problem you break it down into key value pairs and spread it out across a number of processors – abstract it to its simplest components and give them to lots of workers. HDFS is a file system specifically designed to handle LOTS of key value [...]

MapReduce

MapReduce. MapReduce has a language and there is a syntax to this language (like English). Behind MapReduce are concepts that the language implements. You don't need to understand the language to appreciate the elegance of MapReduce, you need a good analogy. Here's mine: It is 1930. Alan Turing and Alonzo Church in England have just [...]

Big Data

Imagine what Big Data can do for you. Big Data is a term, like database, that can mean different but similar things depending on context: Big Data is archetypically the Hadoop Distributed File System (HDFS) and MapReduce. The open source Apache project Hadoop includes HDFS and an implementation of MapReduce. Big Data is a collection [...]
