The database frontier

Jay’s opening lines regarding the final MySQL Conference keynote speaker was: “I work with a lot of data. I think peta-bytes, maybe exa-bytes”. This was relating to Jacek Becla from the Stanford Linear Accelerator Center, giving his presentation on “The Science and Fiction of Petascale Analytics”.

The goal of the Large Synoptics Survey Telescope (LSST) is the storage of 50+ PB of images and 20+ PB data.
Let’s just clarify the size. 20 PB of data = 20 years of HD Movies = 2000 years of 128kb MP3

The next database frontier is obviously building huge databases. What part will MySQL or other relational databases play? Some interesting facts were.

  • The Digital Universe Created 161 Exabytes of data last year.
  • Google, processes 20 petabytes of data per day.

The Operational plan for LSST Project Timeline is 10 years, only starting in 2014. The timeline:

  • 2009 Choosing Technology
  • 2010-2014 constructions
  • 2014-2023 production

The primary goals are: Scale, parallelize, fault tolerant.

Producing IQR and Outlier statistics with SQL

Producing IQR and Outlier statistics with SQL

The interquartile range (IQR) measures the spread of the middle 50% of a distribution — the distance between the first quartile (Q1) and the third quartile (Q3). Combined with Tukey’s 1.

Producing Mode statistics with SQL

Producing Mode statistics with SQL

The mode is the value or values that appear most frequently in a dataset. Unlike the mean or median, it applies naturally to categorical and ordinal data — star ratings, product codes, survey responses — and reveals what is most common, not what is average.

Extending MySQL Capabilies with UDFs, Plugins and Components - Part 2

MySQL offers three different approaches to extending the SQL capabilities with the default product you download and install. These are: User Defined Function (UDF) MySQL Manual MySQL Plugin MySQL Manual MySQL Component MySQL Manual In my prior post I provided a new uuidv function that accepted a numeric argument to return a string of the version of UUID specified.
