dclocal_read_repair_chance and read_repair_chance have been removed in Cassandra 3.11 and 4.x, see https://issues.apache.org/jira/browse/CASSANDRA-13910. if we expose these properties via DDL, Cassandra would fail to consume the CQL statement creating the table when performing migration from Scylla to Cassandra 4.x, as the latter does not understand these properties anymore. currently the default values of `dc_local_read_repair_chance` and `read_repair_chance` are both "0". so they are practically disabled, unless user deliberately set them to a value greater than 0. also, as a side effect, Cassandra 4.x has better support of Python3. the cqlsh shipped along with Cassandra 3.11.16 only supports python2.7, see https://github.com/apache/cassandra/blob/cassandra-3.11.16/bin/cqlsh.py it errors out if the system only provides python3 with the error of ``` No appropriate python interpreter found. ``` but modern linux systems do not provide python2 anymore. so, in this change, we deprecate these two options.
