如何在多个范围内在Accumulo中执行有效删除？

Question

我有一个索引表，其中包含以下架构：

Row   CF    CQ
Name  POB   DOB

我怎样才能有效删除多行（即John Doe：纽约：01/01/75，Jane Doe：Miami：06/21/80）？

Answer 1

使用您要删除的所有BatchDeleter（行）中的setRanges和Range

https://accumulo.apache.org/1.7/apidocs/org/apache/accumulo/core/client/BatchDeleter.html

Answer 2

BatchDeleter deleter= conn.createBatchDeleter("Table Name", new Authorizations(), 1, config);
Collection<Range> ranges = new ArrayList<Range>();
Scanner tableScannerRange= conn.createScanner("TableName", new Authorizations());
tableScannerRange.setRange(new Range("XXXX"));
for (Entry<Key, Value> entry : tableScannerRange) {
                            ranges.add(new Range(entry.getKey().getRow()));
}
deleter.setRanges(ranges);
deleter.delete();

Answer 3

或使用Put Delete

Mutation mutation_data = new Mutation("  ");

                        mutation_data.putDelete(CF,CQ);
