I believe, and it also depends on your config, CL.ONE Should ignore the loss of

is not met and you will get exceptions returned.

It's your replication factor that determines how many nodes contain the data.
So you would set the replication factor to 5 to ensure all nodes contain the
data.
Your consistency level is all based on when should the server return to the

By higher level data I meant the common data.
For example we plan on creating an index using Solr for search but as its

We plan to and have been using it in Dev and QA. There are some bugs that

Sorry to fork this topic, but in "composite indexes" do you mean as strings
or as "Composite()". I only ask cause we have started using the Composite as
rowkeys and column names to replace the use of concatenated strings mainly
for lookup purposes.

Tim do you know if this is the actual reason that is causing the broken

will fix the issue.
