Making the Impossible Possible: Disposable Staging Environments At Scale

Eric Sproul of OmniTI speaks on ZFS Day.

How does one go about running intensive business-intelligence (BI) database queries on rapidly changing data? We found ourselves pondering this question while helping Etsy do periodic reporting on their massive BI database. We harnessed the power of ZFS to create lightweight, yet writable, clones of production data that could be deleted when the report was done. The side effect was that we could also stand up staging environments at any time to test upgrades, schema changes and anything else that needed to be validated against real data.

Four Years Ago / Today

It’s now November, 2012. I will be 50 at the end of this month. Around the time of my birth, my parents – living in Louisiana – participated in the fight for Civil Rights. Their part was small, but it was not without danger. Others, as we know, paid with their lives.

Four years ago, though racism is far from dead in this country, we saw a black man elected president of the United States. I cried with pride, because it showed then how much America deserved to be called a great nation and a world leader.

I have since been often appalled at the number of my fellow citizens who are apparently mortally offended (or fearful) at what made me so happy. They don’t all dare use the racist words of 50 years ago, but it’s there, in code.

The war for Civil Rights is not over. The war for gay rights has barely begun. And the GOP is trying to roll back women’s rights, also hard-won decades ago. They want it to be “their” world again, a world “safe” for straight white men.

Yes, I feel very strongly about this. I was raised to believe in “liberty and justice for all”, though I knew from an early age that that was a goal not yet achieved.

So, if you’re one of those people trying to turn back the tide of history, I want to hear why you think this is a good idea. Step up. You know who you are. I’m waiting.
