Not at all. We (the community) are continuing to invest more on improving the docs because these things are not obvious or well-understood. The read *request* is blocked while the repair of replicas is in progress. To be clear, it is the *request* (singular) that is blocked and *not* some locking mechanism at the partition level (say like LWTs). Other requests (read 2 in your case) will continue to work. Cheers!
