Some interesting things I am finding about Windows Azure

  • Queue messages have a max size of 8kb.
  • Queued messages in azure are typed.
  • If you are interested in #Azure, I would suggest following @smarx on
  • Transaction support will come in future #Azure CTPs.
  • ACID Transactions are only supported on single entity updates at this time in azure.
  • Azure table writes are synchronous.
  • In the commercial release, MS will offer some control over geodistribution and georeplication. Info is scarce at this time.
  • In the CTP, Azure runs in "a single datacenter on the US west coast."
  • The lease timeframe appears to be configurable. The default is 30 seconds.
  • You can hold a lease on message in an azure queue. No one else can see it during the lease. This is good.

These are just some of the things I have found while reading online.  As I find out more, I'll be posting. If you want immediate access to my info, go to and follow me (@wbm)
