    +Blacklisting Partitions (CASSANDRA-12106)
    +This feature allows partition keys to be blacklisted i.e. Cassandra would not process
following operations on those
    +blacklisted partitions.
    +- Point READs
    +Response would be InvalidQueryException.
    +It is important to note that, this would not have any effect on range reads or write
    +How to blacklist a partition key
    +``system_distributed.blacklisted_partitions`` table can be used to blacklist partitions.
Essentially, you will have to
    +insert a new row into the table with the following details:
    +- Keyspace name
    +- Table name
    +- Partition key
    +The way partition key needs to be mentioned is exactly similar to how ``nodetool getendpoints``

    not that I could find. There is getendpoints.txt, but that doesn't go into required details
around partition key
