我在DSE cassandra实例中有一个表,其中包含以下字段,

customerid uuid,
emailaddress text,
firstname text,
lastname text
PRIMARY KEY is on (customerid, emailaddress)

我已经定义了schema.xml,如下所示,

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<schema name="customer" version="1.5">
<types>
        <fieldType class="org.apache.solr.schema.TextField" name="TextField">
                <analyzer>
                        <tokenizer class="solr.StandardTokenizerFactory"/>
                        <filter class="solr.LowerCaseFilterFactory"/>
                </analyzer>
        </fieldType>
        <fieldType class="solr.StrField" name="StrField"/>
        <fieldType class="solr.TrieIntField" name="int"/>
        <fieldType class="solr.UUIDField" name="uuid"/>
</types>
<fields>
        <field indexed="true" multiValued="false" name="emailaddress" stored="true" type="TextField"/>
        <field indexed="true" multiValued="false" name="customerid" stored="true" type="uuid"/>
        <field indexed="true" multiValued="false" name="lastname" stored="true" type="TextField"/>
</fields>
<uniqueKey>customerid</uniqueKey>
</schema>

当尝试在命令行上创建核心时,我得到以下异常,

$ curl -u db_admin:test123 "http://localhost:8983/solr/admin/cores?action=CREATE&name=ks_01.customer"

"...<str name="msg">com.datastax.bdp.search.solr.CassandraIndexSchema$ValidationException: Clustering parts that are not part of the unique key must be multi-valued.</str><str name="trace">org.apache.solr.common.SolrException: com.datastax.bdp.search.solr.CassandraIndexSchema$ValidationException: Clustering parts that are not part of the unique key must be multi-valued....."

有人可以通过一些详细解释来建议我在这里失踪的内容。谢谢。

答案 0 :(得分:1)

我对DSE一无所知,但在我看来你犯了一个语法错误[1]:

<uniqueKey>customerid</uniqueKey> 

应该是

<uniqueKey>(customerid, emailaddress)</uniqueKey>
