Known applications of MapReduce

Most of the actual MapReduce applications I’ve heard of fall into a few areas:

That covers all MapReduce apps I recall hearing about via commercial companies and users, and also includes most of what’s in the two big sources I found online. To wit:

1. In a slide presentation, Google offers the following applications of MapReduce:

2. The Hadoop applications page offers a rich trove of applications. Excerpts include:

There also were some research apps and some general processing speed-up apps I found harder to excerpt.

    There is a coding tutorial available at this link in the middle of the page:

    Key things to note about Greenplum’s MR implementation:
    – It’s very similar in form and expression to Google and Hadoop
    – Extensions for Joins and Pipelined task execution
    – Native parallel file access
    – Parallelism is full and transparent to the programmer

    In summary: we have implemented MapReduce within which you can write SQL, Perl, Python and many more languages. It is straightforward to use MR programs written for Hadoop or Google and port them to Greenplum.

    […] По существу, вы можете сделать все, что угодно с одной записью* – это шаг map. Но вы сильно ограничены в том, как вы можете объединить информацию о многих (часто промежуточных) записях – это шаг reduce. Тем не менее, шаг reduce позволяет вам выполнять подсчет, суммирование и другие операции агрегирования. Сей факт, вкупе с универсальной мощью шагов map, делает MapReduce полезным, по меньшей мере, для трех важных классов приложений: […]

  12. Winning with Data: Aster Data Systems Blog » Blog Archive » The Importance of Visibility Across Rows on April 22nd, 2009 2:49 pm

    […] Examples abound. Consider a SQL/MR function which applies a complex model to score the data in the database, whether it’s scoring a customer for insurance risk, scoring an internet user for an ad’s effectiveness, or scoring a snippet of text for its sentiment. These functions often construct a data structure in memory to accelerate scoring, which works very well with the SQL/MR API: build the data structure once and reuse it across a large number of rows. […]

    Hi there just wanted to give you a quick heads up. The text in your post seem to be running off the
    screen in Ie. I’m not sure if this is a formatting issue or something
    to do with web browser compatibility but I thought I’d post to
    let you know. The design look great though! Hope you get the issue solved soon.
