brutecat on "Materialized View"

Hi there,

I am somewhat new to Cassandra and DataStax, so sorry if this is a bit naive.

I am just looking at the Twissandra example of view population. This is on the page:

http://www.datastax.com/docs/0.7/data_model/twissandra

and the relevanrt section is at the bottom:

"Adding a Tweet¶

To add a tweet, we have to do the following:

Create the tweet in the TWEET column family
Add it to the user’s row in USERLINE
Add it to the PUBLIC_USERLINE_KEY row in USERLINE
Add it to the timelines of the followers of the user"

How are cases handled where the process of updating the views aborts (e.g. client crashes).

Is this the only mechanism for updating the views, or is there something built into Cassandra for view definition which works in the background along with replication?

Thanks,

Stan
