我有一个列族,名为domes\u api,其中包含rowkey的行数:/bt=??/bm=??/mk=??/se=??:

/bt=1/bm=MN/mk=344/se=23394/odds_api
/bt=1/bm=BY/mk=344/se=23394/odds_api
/bt=1/bm=SN/mk=344/se=23394/odds_api
/bt=1/bm=BB/mk=344/se=23394/odds_api
/bt=1/bm=SF/mk=344/se=23394/odds_api
/bt=1/bm=XY/mk=344/se=23394/odds_api

我想根据bm值列表进行过滤,也称为基于bm=sf,bb,mn的过滤。
为此,我创建了一个filterlist of must \u pass \u one with 1 to many rowfilters(取决于用户请求的值数量)

public ResultScanner scan(String id , List<String> bms) throws BigTableGetException {
    try{
        Table table = connection.getTable(TableName.valueOf(this.tableName));
        Scan scan = new Scan();
        scan.addFamily(Bytes.toBytes("odds_api"));
        FilterList mainFilterList = new FilterList(FilterList.Operator.MUST_PASS_ONE);

        bms.stream()
                .forEach(bm -> {
                    mainFilterList.addFilter(new RowFilter(CompareOp.EQUAL, new RegexStringComparator("/bt="+id+"/bm="+bm+".*")));

                });
        System.out.println("this is the filter list " + mainFilterList.toString());

        scan.setFilter(mainFilterList);
        return table.getScanner(scan);
    }catch (IOException ex){
        throw new BigTableGetException("Failed to get rows in BigTable", ex);
    }
}

(我知道——对一个foreach来说毫无意义的流!)
如果只指定了一个bm,则可以正常工作,打印语句:

this is the filter list FilterList OR (1/1): [RowFilter (EQUAL, /bt=1/bm=B4.*)]

但是,如果指定了多个,则返回所有内容,打印语句:

this is the filter list FilterList OR (2/2): [RowFilter (EQUAL, /bt=1/bm=B4.*), RowFilter (EQUAL, /bt=1/bm=PP.*)]

事实上,如果我输入两个或多个“不正确”的bm值,它仍然返回所有内容!
我读过:https://www.oreilly.com/library/view/hbase-the-definitive/9781449314682/ch04.html
我也试过移动bt=?筛选出一个单独的必须通过所有筛选,然后有另一个列筛选bm=?

this is the filter list FilterList AND (2/2): [FilterList AND (1/1): [RowFilter (EQUAL, .*bt=1)], FilterList OR (2/2): [RowFilter (EQUAL, .*/bm=B4.*), RowFilter (EQUAL, .*/bm=PP.*)]]

同样的问题。
我一定是错过了什么明显的,任何帮助将不胜感激。

你考虑过用一个正则表达式吗?”/bt=foo/bm=(a | b | c | d)。*“应该可以。
另外,请提出一个问题https://github.com/googlecloudplatform/cloud-bigtable-client. 在客户端代码中似乎确实有一个bug。
