    The fact that the huge data mining companies like Equifax, Facebook, and Google are building such databases is far more concerning from a privacy point of view.

    In contrast, Microsoft's "Windows Subsystem for Linux" is absolutely NOT a Linux, but has a GNU environment because it does include:

    • Bash (part of GNU)
    • glibc (part of GNU)
    • GNU coreutils (part of GNU)

  13. What kind of data really needs to set powered off for 40 years, though?

    Because data grows so fast, I imagine all 40 year old data will be absolutely tiny in comparison, and fit in the corner of whatever live/hot storage is in use.

    I do like the premise of companies storing data locally.

    I think all the "cloud backup" advocates have it backwards. The cloud's the best place for live data; but companies (and people) should have local backups of their clouds.

  24. ported large cluster from SQL Server to Postgres.. on Microsoft Brings SQL Server To Linux (betanews.com) · · Score: 5, Interesting
    TL/DR: About a 5x-10x CPU and Disk I/O improvement migrating a pretty large project from [a major proprietary database mentioned in the article]* see edit below to Postgres. CPU and Disk I/O Graphs below.

    Here's one data point - based on from experience migrating a pretty big system from [a major proprietary database mentioned in the article] to Postgres, I think the two biggest advantages Postgres has are:

    GIST and GIN indexes (and soon BRIN indexes), and

    Writeable CTEs.

    We migrated a very busy, pretty large (24 CPU core, 256GB RAM, 20TB disk space) system from [a major proprietary database mentioned in the article] to Postgres about a year ago. These graphs measuring CPU and disk activity provide a nice visualization of the improvement:

    http://imgur.com/a/bp2ky

    Note that with [a major proprietary database mentioned in the article], all 24 CPU cores in the system were over 40% utilized (and growing) 24x7 most days a year. After a pretty naive port (November to May in the graph) the CPU load fell to an average of about 10%, and the disk array's queue length fell from painful to near zero. After adding some Postgres-specific code, we got it down to an average of near 5% (shown in the most recent month in the graph).

    CPU differences seem to have been mostly related to the availability of GIN indexes in Postgres, which can be much more efficient on certain types of data (like the OpenStreetMap road network).

    Disk I/O improvements seems to be mostly related to Postgres's far more compact storage of XML data. Seems SQL Server stores XML data using 2-bytes-per-character for the data itself; and on top of that adds extremely large indexes. In contrast, the "toast" feature in Postgres means the XML data takes an average of less than one byte per character for the data and its "functional index" feature allowed for far more compact indexes. One of our XML-heavy databases went from over 600GB in SQL Server down to 140GB in Postgres, with more efficient indexes.

    For a few months we tried to stay database-agnostic so it'd be easy to port back if we needed to -- but after a while we started adding Postgres specific changes. The benefits of those Postgres specific changes can be seen near the end of those graphs. An enormous improvement occurred when we changed the inserts and updates to use the Writable CTE features following recommendations someone outlined here

    .

    In the end, Postgres looks to me like it's saving us like 5X in hardware costs as we continue to grow.

    Edit: I'm told this proprietary database vendor dislikes users publishing benchmark results comparing their software to F/OSS databases. I'd argue that this is more of an anecdote than a benchmark; but just in case I edited the comment to remove the vendor and product name from the parts that talk about performance.

    Disclaimer: As mentioned in a comment below, we tried to tune each the systems to the best of our team's abilities, but aren't really experts in tuning either database system. No doubt each system's results could be improved by people who were deeply available with each databases internals (which I argue is much easier to find for Postgres, since its mailing lists have thousands of people familiar with the internal code).
