bigdata is cool but...
hard to set up and monitor
expensive cluster
not interactive enough
@supercoco9#DevoxxBigquery
bigdata is doing a fullscan to 330MM rows, matching them against a regexp, and getting the result (223MM rows) in just 5 seconds
Google BigQuery
Data analysis as a service
http://developers.google.com/bigquery
Based on “Dremel”
Specifically designed for interactive queries over
petabytes of real-time data
@supercoco9#DevoxxBigquery
Your only worries
•Load data
•Query the dataset
loading data.
You just send the data in
text (or JSON) format
up to 100K inserts per second
in stream mode
It's just SQL
select name from USERS order by date;
select count(*) from users;
select max(date) from USERS;
select sum(total) from ORDERS group by user;
@supercoco9#DevoxxBigquery
Subselect and joins out of the box
SELECT Year, Actor1Name, Actor2Name, Count FROM (SELECT Actor1Name, Actor2Name, Year, COUNT(*) Count, RANK() OVER(PARTITION BY YEAR ORDER BY Count DESC) rankFROM
(SELECT Actor1Name, Actor2Name, Year FROM [gdelt-bq:full.events] WHERE Actor1Name < Actor2Name and Actor1CountryCode != '' and Actor2CountryCode != '' and Actor1CountryCode!=Actor2CountryCode), (SELECT Actor2Name Actor1Name, Actor1Name Actor2Name, Year FROM [gdelt-bq:full.events] WHERE Actor1Name > Actor2Name and Actor1CountryCode != '' and Actor2CountryCode != '' and Actor1CountryCode!=Actor2CountryCode),
WHERE Actor1Name IS NOT nullAND Actor2Name IS NOT nullGROUP EACH BY 1, 2, 3HAVING Count > 100)
WHERE rank=1ORDER BY Year

Things you always wanted to try but were too scared to
select count(*) from publicdata:samples.wikipedia where REGEXP_MATCH(title, "[0-9]*") AND wp_namespace = 0;
