HH in 1.X+ is very good, but it is still an optimisation for achieving
consistency.

Run a repair and see.

I hope this works for me for the next reasons: I have quite large RF (6
datacenters, each carry one replica of all dataset), read and write at
CL ONE, relatively small TTL - 10 days, I have no deletes, servers
almost never
Well, if everything works 100% at any time there should be nothing to
repair, however with a distributed cluster it would be pretty rare for that
to occur. At least that is how I interpret this.

BTW, I heard that we don't need to run repair if all your data have TTL,
all HH works, and you never delete your data.

Yes, I personally have configured it to perform a repair once a week, as
the GCGraceSeconds is at 10 days.
This is also what's in the manual

Hello
I have follow question, if we Read and write to cassandra claster with
QUORUM consistency level, does this allow to us do not call nodetool repair
regular? (i.e. every GCGraceSeconds)
