Rather than passing a pointer to a cql_stats member corresponding to the statement type, pass a reference to a cql_stats object and use statement_type, which is already stored in modification_statement, for determining which counter to increment. This will allow us to account conditional statements, which will have a separate set of counters, right in modification_statement::execute() - all we'll need to do is add the new counters and bump them in case execute_with_condition is called. While we are at it, remove extra inclusions from statement_type.hh so as not to introduce any extra dependencies for cql_stats.hh users. Message-Id: <20191022092258.GC21588@esperanza>
