Beeline as Hive client
by Madhumitha Viswanathan 02 Oct '18

02 Oct '18

Hi all, For all Hive users using stat1002/1004, you might have seen a deprecation warning when you launch the hive client - that claims it's being replaced with Beeline. The Beeline shell has always been available to use, but it required supplying a database connection string every time, which was pretty annoying. We now have a wrapper <https://github.com/wikimedia/operations-puppet/blob/production/modules/role…> script setup to make this easier. The old Hive CLI will continue to exist, but we encourage moving over to Beeline. You can use it by logging into the stat1002/1004 boxes as usual, and launching `beeline`. There is some documentation on this here: https://wikitech.wikimedia.org/wiki/Analytics/Cluster/Beeline. If you run into any issues using this interface, please ping us on the Analytics list or #wikimedia-analytics or file a bug on Phabricator <http://phabricator.wikimedia.org/tag/analytics>. (If you are wondering stat1004 whaaat - there should be an announcement coming up about it soon!) Best, --Madhu :)

Wikipedia aggregate clickstream data released
by Dario Taraborelli 16 Jan '18

16 Jan '18

We’re glad to announce the release of an aggregate clickstream dataset extracted from English Wikipedia http://dx.doi.org/10.6084/m9.figshare.1305770 <http://dx.doi.org/10.6084/m9.figshare.1305770> This dataset contains counts of (referer, article) pairs aggregated from the HTTP request logs of English Wikipedia. This snapshot captures 22 million (referer, article) pairs from a total of 4 billion requests collected during the month of January 2015. This data can be used for various purposes: • determining the most frequent links people click on for a given article • determining the most common links people followed to an article • determining how much of the total traffic to an article clicked on a link in that article • generating a Markov chain over English Wikipedia We created a page on Meta for feedback and discussion about this release: https://meta.wikimedia.org/wiki/Research_talk:Wikipedia_clickstream <https://meta.wikimedia.org/wiki/Research_talk:Wikipedia_clickstream> Ellery and Dario

Request stream data set for cache tuning
by Daniel Berger 31 Aug '16

31 Aug '16

Hi everyone, I'm a phd student studying mathematical models to improve the hit ratio of web caches. In my research community, we are lacking realistic data sets and frequently rely on outdated modelling assumptions. Previously, (~2007) a trace containing 10% of user requests issued to the Wikipedia was publicly released [1]. This data set has been used widely for performance evaluations of new caching algorithms, e.g., for the new Caffeine caching framework for Java [2]. I would like to ask for your comments about compiling a similar (updated) data set and making it public. In my understanding, the necessary logs are readily available, e.g., in the Analytics/Data/Mobile requests stream [3] on stat1002, with a sampling rate of 1:100. As this request stream contains sensitive data (e.g., client IPs), it would need anonymization before making it public. It would be glad to help with that. The previously released data set [1] contains no client information. It contains 1) a counter, 2) a timestamp, 3) the URL, and 4) an update flag. I would additionally suggest to include 5) the cache's hostname, 6) the cache_status, and 7) the response size (from the Wikimedia cache log format). I believe this format would preserve anonymity, and would be interesting for many researchers. Let me know your thoughts. Thanks, Daniel Berger http://disco.cs.uni-kl.de/index.php/people/daniel-s-berger [1] http://www.wikibench.eu/?page_id=60 [2] https://github.com/ben-manes/caffeine/wiki/Efficiency [3] https://wikitech.wikimedia.org/wiki/Analytics/Data/Mobile_requests_stream

Pagecount Datasets to be Deprecated at the end of May
by Dan Andreescu 08 Aug '16

08 Aug '16

Just a reminder, we will be deprecating the pagecounts datasets at the end of May, as we mentioned earlier this year [0]. This means these files will remain there to be used by researchers but new files will not be generated in the future. *Pagecounts datasets that will be deprecated* pagecounts-raw pagecounts-all-sites Options for switching to the new datasets [1]: pageviews for the same format but better quality data pagecounts-ez for compressed data [0] https://lists.wikimedia.org/pipermail/analytics/2016-March/005060.html [1] https://dumps.wikimedia.org/other/analytics/

Survey for Wikipedia readers
by Vipul Naik 14 Jul '16

14 Jul '16

Hello Wikimedia analytics mailing list, As part of research into how people read Wikipedia, a friend and I created a short survey. We are interested in seeing how people on this mailing list (not a representative sample of Wikipedia readers for sure!) fill the survey. The survey should take 2 to 10 minutes to complete. https://www.surveymonkey.com/r/QBCCVFY I would also appreciate if any of you have the ability to circulate the survey to a different audience. If you are interested in doing that, please let me know (off-list, if you prefer) and I will give you a separate URL through which to do so for each such audience. The URLs represent different audiences to whom the survey is shared so that it is easier to understand how responses differ based on audience. Any feedback on the survey questions would also be appreciated, on- or off-thread. Thank you very much! Vipul

Clickhouse
by Gilles Dubuc 09 Jul '16

09 Jul '16

This might be of interest: https://clickhouse.yandex/ ClickHouse is an open-source column-oriented database management system that allows generating analytical data reports in real time. ClickHouse manages extremely large volumes of data in a stable and sustainable manner. It currently powers Yandex.Metrica, world’s second largest web analytics platform, with over 13 trillion database records and over 20 billion events a day, generating customized reports on-the-fly, directly from non-aggregated data. This system was successfully implemented at CERN’s LHCb experiment to store and process metadata on 10bn events with over 1000 attributes per event registered in 2011.

Adding analytics@ a public e-mail list where you can post questions such as this one. >that doesn’t tell us how often entities are accessed through Special:EntityData or wbgetclaims >Does this data already exist, even in the form of raw access logs? Is this data always requested via http from an api endpoint that will hit a varnish cache?

I think I have mentioned this before on an e-mail thread but without knowing the details of what you want to do we cannot give you a time estimate. What are the exact metrics you are interested on? Is the project described anywhere in meta?

Hi! Tomorrow morning (Jun 30th - CET timezone) I'd need to reboot stat1002, stat1003 and stat1004 for kernel upgrades (Ubuntu security patches). This could potentially terminate long running queries or jobs, so please ping me on IRC or email me if your work can't be postponed or stopped. Thanks! Regards, Luca

Proposal to reopen the "Unacceptable behavior" section
by Matthew Flaschen 29 Jun '16

29 Jun '16

Yaron Koren has proposed to reopen the "Unacceptable behavior" section (https://www.mediawiki.org/wiki/Talk:Code_of_Conduct/Draft#Suggested_change_…). His perspective and mine are given on the talk page. In brief: * He disagrees with how "marginalized and otherwise underrepresented groups" and "encouraged" are handled in the original text. * I support the current text and process, and have explained why on the talk page. Thanks, Matt Flaschen
