我正在使用DSE Cassandra并希望使用solr_query,因此创建了Keyspace如下:
create keyspace demo with replication = {'class': 'NetworkTopologyStrategy', 'Solr': 3};
创建下表:
create table demo.onlinetransactions
( unique_tran_id text, user_id text, account_type text,
account_id text, create_ts timestamp, data text,
primary key (unique_tran_id) );
但是,当我尝试在此表中插入记录时,我收到错误,如下所述:
insert into demo.onlinetransactions (unique_tran_id, user_id,
account_type, account_id, create_ts, data)
values ('trans1', 'user1', 'creditcard',
'1234567890123451', '2015-01-01 09:00:00', '{amount:100.00,vendor:Amazon}');
错误:
NoHostAvailable: ('Unable to complete the operation against any hosts',
{<Host: 127.0.0.1 dc0>: Unavailable('Error from server: code=1000
[Unavailable exception]
message="Cannot achieve consistency level ONE"
info={\'required_replicas\': 1, \'alive_replicas\': 0,
\'consistency\': \'ONE\'}',)})
我需要通过哪些配置设置验证我是否能够使用&#34; NetworkTopologyStrategy&#34;在键区空间中插入记录?和#34; Solr&#34;设定吗
此外,我可以在键空间中插入记录,如下所示(但这不是我想要使用的Solr。):
CREATE KEYSPACE user WITH replication =
{'class': 'SimpleStrategy', 'replication_factor': '3'}
AND durable_writes = true;
答案 0 :(得分:2)
在KeySpace中指定正确的数据中心名称之后,solr_query使用NetworkTopologyStrategy作为复制策略。
