Quiet Saturday Thoughts

April 5th, 2008

Thinking again about distributed log oriented writes as a better architecture for a whole class of persistent data we need to deal with. Atomic appends are actually one of the least appreciated features in GFS, and certainly the most critical feature HDFS is missing. Right now I’m not even sure I’m supposed to be worrying, my back of the napkins are saying maybe 10-20mil daily appends across 3-4mil queues is just like running a big mail install right? (remind me to look at Maildir again)

Also contrary to TC’s breathy article BigTable is not much like SimpleDB (other then they’re both ways of storing and retrieving data which aren’t MySQL) in that it doesn’t give you querying, just limited range scans on rows, and it seems to be really really expensive to add new columns (at least whenever I talk to Gengineers, they seem to flinch at the concept)

Meanwhile I’m still waiting on DevPay for SimpleDB, before I get into it in a big big way.

Personal Data Stores and the Network

October 31st, 2007

Thinking about what “personal data stores” are going to look like, how this interacts with decentralized models for community services, (I swear I’ve written something more recent then 2005 on that topic, but can’t find it), mulling models for updating clouds, wondering if projects like G’s OpenSocial, and Portable Social Networks are a step forward or back, speculating that digital curation is a viable near future business model, and that individual curations would work well as shareable social media objects.

Nothing necessarily novel. Just where my head is at.

Amazon reveals its secret key-data overlords from the planet Cloud

October 3rd, 2007

Only the barest of glances at Dynamo so far, and by far the most interesting pieces are going to be how they do the scalable high availability, and of course we’re talking about “Werner Vogels Scalability(tm)“, but I was immediately struck, [as Sam was](http://intertwingly.net/blog/2007/10/03/Key-Data ), by the this pattern key+data we’re seeing:

  • memcached (everybody is using it)
  • CouchDb (everybody is talking about it)
  • Berkely DB (Bloglines and Yahoo to name just two, plus Google, thanks Steve)
  • Facebook Data Store API
  • and now Dynamo.

Meanwhile Assaf argues well that not all keys are created equal

Facebook Data Store API

August 10th, 2007

When I heard that f.bk had a new Data Store API was thinking “Wow! That’s actually hard!”.

But if you read it closer you’ll notice the operations map to what can de done in memcache (down to transactions are handled via atomic auto-increments) with a bit of cleverness, and some persistence. (pun intended) Still a nice step towards making developing f.bk apps a bit less eye-pokey-outty

Everyone is building the giant hash table in the clouds.
