Datastax 手册说我可以使用“USING CONSISTENCY”语法更改一致性级别。 http://www.datastax.com/docs/1.1/references/cql/cql_data_types#specifying-consistency-level
但是,Cassandra cqlsh 报告使用一致性的错误请求。
cqlsh:db_simple> show version
[cqlsh 2.3.0 | Cassandra 1.2.3 | CQL spec 3.0.0 | Thrift protocol 19.35.0]
cqlsh:db_simple> SELECT * FROM test WHERE a=1;
a | b
---+---------
1 | example
cqlsh:db_simple> SELECT * FROM test USING CONSISTENCY ONE WHERE a=1;
Bad Request: line 1:19 missing EOF at 'USING'
我想念什么?谢谢。
