TimestreamMetaIterator分页会取出所有数据

参考该地址实现：https://help.aliyun.com/document_detail/114347.html?spm=a2c4g.11186623.6.615.17132345T3bKeQ

TimestreamMetaIterator iter1 = db.metaTable()
                .filter(filter)
                .identifierOnly()       // 只返回identifer
                .fetchAll();
        System.out.print(iterator.getTotalCount());   //获取命中的时间线条数
        while (iter1.hasNext()) {
            System.out.print(iterator.next().toString());
        }
    public boolean hasNext() {
        if (isBufferHasData()) {
            return true;
        }
        byte[] token = response.getNextToken();

        while (token != null) {
            request.getSearchQuery().setToken(response.getNextToken());
            request.getSearchQuery().setOffset(0);
            fetchData(request);
            if (isBufferHasData()) {
                return true;
            }
            token = response.getNextToken();
        }
        return false;
    }

上述实现会取出所有数据，是否需要把isBufferHasData提出公共方法出来。目前实现分页，不能用这个方法，只能自己写实现

Start at TimestreamMetaIterator.hasNext and inspect isBufferHasData, response.getNextToken, and fetchData. Reproduce the paginated fetch described in the issue, then verify that iteration respects pagination instead of continuing until all data is retrieved; no test or source file is named in the report.
