Engineering @ Facebook Facebook Engineers launch new privacy controls giving users even greater control over the information they share and the audiences with whom they share it.

UPDATE on Wednesday, July 8: We have begun testing the new privacy settings with a small percentage of users. Each user within the test group will see several Transition Tools that will help them select the level of privacy they are most comfortable with and introduce the new, simpler settings...

Hi Schubert,

We do compress the data stored in Hive using gzip over Hadoop SequenceFiles. We also use it to regularly pre compute rollups for a number of our internal data processing pipelines. We do want to extend the syntax to support rollups and cube computations through constructs in the SQL standard and this is something that we have talked ... Read Moreabout a lot and will happen in future. As regards latency, as our integration with Microstrategy proceeds (we are building an ODBC driver), this will become more and more important. HIVE-417 should solve some of those issues. I think Prasad had uploaded a lot more details there but it would be good to comment on the JIRA saying that you are interested in that feature and ask for more details. For the very short term, you can address latencies by loading the pre computed summaries to a mysql db and serving them from there.

Glad to hear that you are using this and liking it.

Haha, are you people for real? First off, the website you're discussing isn't even a facebook.com address, which is the absolute only way it'd be legit, and second, YOU CLICKED IT. Facebook has nothing to do with your mouse and your willingness to click on an external link. What, do you want them to send over a nanny to watch you surf the internet? Your fault, your problem.
