Web Analytics Databases Get Even Larger
CurtMonash writes "Web analytics databases are getting even larger. eBay now has a 6 1/2 petabyte warehouse running on Greenplum — user data — to go with its more established 2 1/2 petabyte Teradata system. Between the two databases, the metrics are enormous — 17 trillion rows, 150 billion new rows per day, millions of queries per day, and so on. Meanwhile, Facebook has 2 1/2 petabytes managed by Hadoop, not running on a conventional DBMS at all, Yahoo has over a petabyte (on a homegrown system), and Fox/MySpace has two different multi-hundred terabyte systems (Greenplum and Aster Data nCluster). eBay and Fox are the two Greenplum customers I wrote in about last August, when they both seemed to be headed to the petabyte range in a hurry. These are basically all web log/clickstream databases, except that network event data is even more voluminous than the pure clickstream stuff."
At least these won't get out in the open that easily because someone copied them to an USB drive and lost it somewhere.
Yesy. It mighty take a whiley to get used to, but I thinky it's quite a plusy overall.

Do you miss Firefox? Try Pale Moon.
...but do they move every zig?
Does the black hole effect help with compression?
With all that user data, you'd think they would know me better by now. But I still get these lame recommendations.
