Everyone Talks About Big Data, But What Does That Actually Mean?

 

Back in March, I wrote a post that introduced Gartner’s hype cycle.  This hype cycle provides an actual graphical representation of the buzzword fatigue that we in the industry feel so acutely.  If you look back over the last few years, you won’t have a hard time thinking of examples.  In that earlier post, I talked about the term cloud.  But terms like internet of things, micro-services, and big data might also come to mind.

 

Today, I want to talk about this latter term, big data.  Unlike some of the other terms that wind their way along Gartner’s hype cycle, this one has maddening uncertainty cooked right into its name.  The word big offers so much vagueness that …

Column Store Database Benchmarks: MariaDB ColumnStore vs. Clickhouse vs. Apache Spark

This blog shares some column store database benchmark results, and compares the query performance of MariaDB ColumnStore v. 1.0.7 (based on InfiniDB), Clickhouse and Apache Spark.

I’ve already written about ClickHouse (Column Store database).

The purpose of the benchmark is to see how these three solutions work on a single big server, with many CPU cores and large amounts of RAM. Both systems are massively parallel (MPP) database systems, so they should use many cores for SELECT queries.

For the benchmarks, I chose …

Database Challenges and Innovations. Interview with Jim Starkey

“Isn’t it ironic that in 2016 a non-skilled user can find a web page from Google’s untold petabytes of data in millisecond time, but a highly trained SQL expert can’t do the same thing in a relational database one billionth the size?.–Jim Starkey.

I have interviewed Jim Starkey. A database legendJim’s career as an entrepreneur, architect, and innovator spans more than three decades of database history.

RVZ

Q1. In your opinion, what are the most significant advances in databases in the last few years?

Jim Starkey: I’d have to say the “atom programming model” where a database is layered on a substrate of peer-to-peer replicating distributed objects rather than disk files. The atom programming model enables scalability, redundancy, high availability, and distribution not available in traditional, disk-based database …
