Benjamin Lerer commented on CASSANDRA-8437:
-------------------------------------------
[~slebresne] I just wanted to double check before creating the new patch. Are
you sure about your last comment? It seems to conflit with the previous one.
The patch need to be modified anyway, as it will produce an error if sombody
try to use nodetool with an older 2.1 release (similar to CASSANDRA-8796).

> I don't believe we track how often read results in a digest mismatch but we
> should since that could directly impact read performance in practice.
> Once we have that data, it might be that some workloads (write heavy most
> likely) ends up with enough mismatches that going to the data read is more
> efficient in practice. What we do about it it step 2 however, but getting the
> data is easy enough.
