Because in theory, corruption of your repaired dataset is possible, which incremental repair won’t fix.
In practice pre-4.0 incremental repair has some flaws that can bring deleted data back to life in some cases, which this would address. You should also evaluate whether pre-4.0 incremental repair is saving you time. The same flaws can cause *a lot* of over streaming, which may negate the benefit of repairing only the unrepaired data. > On Nov 2, 2017, at 2:17 AM, dayu <sdycre...@163.com> wrote: > > https://docs.datastax.com/en/cassandra/3.0/cassandra/operations/opsRepairNodesWhen.html > <image.png> > So you means i am misleading by this statements.
