Thanks Avinash

 

It's sad to see engineers ready to switch from one sol= ution to another, simply because they hear rumors about Facebook or some other la= rge website moving away from it. The part the really bothers me is how people w= ere ready to look for an alternative solution before they even verified this ru= mor or even heard the reason behind the rumor.

 

I would love to hear more about data modeling with Cassandra. I have gather a lot of good information from reading various presentations by Benjamin Black, Jonathan Ellis and others. The most important piece of the puzzle is to understand how you intend to access the data and then model everything based upon that.

I had the opportunity t= o talk with some Facebook infrastructure
engineers in San Francisco over the past few weeks. They are no longer
using Cassandra, even for inbox search.

Inbox search was intended to be an initial push for using Cassandra more broadly, not the primary target of the Cassandra design. Unfortunately,
Facebook's engineers later decided that Cassandra wasn't the right
answer to the right question for Facebook's purposes.

That decision isn't an indictment of Cassandra's capability; it's
confirmation that Cassandra isn't everything to everyone. But we already knew that. :-)
