Due to the tombstone,we have set GC_GRACE_SECONDS to 6 hours.And for a huge table with 4T size,repair
is a hard thing for us.

You should run repairs every GC_GRACE_SECONDS. If a node is overloaded/goes down, you should
run repairs. LOCAL_QUORUM will somewhat maintain consistency within a DC, but certainly doesn't
mean you can get away without running repairs. You need to run repairs even if you are using
QUORUM or ONE.​
