Hi,

Because of we can't use inconsistent write if we use indexed table and condition operations which indexes based on (this staff requires the state of data), we have one more issue.

If we want to make write with consistency level ONE (WEAK) to the indexed table, we will have 2 variants:
1. Carry out the operation successfully and implicitly make write to the indexed table with minimally possible consistency level for it (QUORUM);
2. Raise an exception, that we can not perform this operation and list all possible CLs for this operation.

I personally prefer the 2nd variant. So, does anybody have some objections or maybe another ideas?
