Subject enforcing ordering
Date Tue, 08 May 2012 09:35:22 GMT
Hi,

I'm wondering if there is a common 'pattern' to address a scenario we will
have to deal with.

We will be storing a set of Column/Value pairs per Key where the
Column/Values are read from a set of files that we download regularly. We
need the loading to be resilient and we can receive corrections for some of
the Column/Values that can only be loaded after the initial data has been
inserted.

The challenge we have is that we have a strong preference for active/active
loading of data and can't see how to achieve this without some form of
serialisation (which Cassandra doesn't support - correct ?)

thanks
