Stefania commented on CASSANDRA-12014:
--------------------------------------

Thanks for the review and the rebase. I've updated my 3.0 
[branch|https://github.com/stef1927/cassandra/commits/12014-simplified-3.0] 
with the rebased code. The CI results don't look too good, there are several 
dtest failures and the unit tests did not run. I've launched CI on our servers 
for 3.0. I'll merge to 3.0, 3.11 and trunk once I have the results. I don't 
expect any problems but just in case.

> I believe this can be fixed by raising the min_index_interval, but we should 
> have a better method of coping with this than throwing the AE.
