Got an interesting question from @Quora today: How much knowledge does the average Google engineer have about their infrastructure? How much Borg knowledge is needed in order to set up or deploy a project? // @jbeda @bgrant0607 @thockin

BCL was used by everyone using Borg pretty much when I was there. There are good docs and patterns. It only trips people up as they try to do more complicated things. There are sharp edges for sure though.
Yes, vast amounts of BCL. This is changing. I hope to be able to talk about it more soon. One thing I mentioned in my Declarative App. Mgmt. doc is that declarative data models were layered both over and under BCL because it proved to be an obstacle to automation.
