Answer 1

您需要提供部分数量和行数的返回值。默认情况下为0

 public void run() {
     Cluster cluster = getConnection();
     Session session = cluster.connect("db");
     LOGGER.info("Starting ...");
     actualToken = -9223372036854775808;
     boolean run = true;
     int print = 0;

     while ( run ) {
         if (maxTokenReached(actualToken)) {
             LOGGER.info("Max Token Reached!");
             break;
         }
         SimpleStatement stmt = new SimpleStatement(queryBuilder(actualToken));
         stmt.setConsistencyLevel(ConsistencyLevel.ALL);
         ResultSet resultSet = session.execute(stmt);

         Iterator<Row> rows = resultSet.iterator();
         if ( !rows.hasNext()){
             break;
         }

         List<String> rowIds = new ArrayList<String>();

         while (rows.hasNext()) {
             Row row = rows.next();

             Long leadTime = row.getLong("my_column");
             if (myCondition(myCollumn)) {
                 String rowId = row.getString("key");
                 rowIds.add(rowId);
             }

             if (!rows.hasNext()) {
                 Long token = row.getLong("token(rowid)");
                 if (!rowIds.isEmpty()) {
                     LOGGER.info(String.format("Keys found! RowId's: %s ", rowIds));
                 }
             actualToken = nextToken(token);
             }
         }
      }
     LOGGER.info("Done!");
     cluster.shutdown(); 
  }

public boolean maxTokenReached(Long actualToken){
     return actualToken >= maxToken; 
 }

 public String queryBuilder(Long nextRange) {
     return String.format("select token(key), key, my_column from mytable where token(key) >= %s limit 10000;", nextRange.toString()); 
 }

 public Long nextToken(Long token) {
     return token + 1; 
 }

确保tableview没有连接到视图控制器的程序数据源，numberOfCells / numberOfSections / cellForRow方法覆盖静态单元格
