使用Datastax DSE 4.0.3在solr中映射timeuuid时出错

我有一个列系列,其中包含timeuuid作为列的id(它是时间序列)以及构成分区键的其他几列。它还包含未分类的列,其中包含应该可搜索的数据(通过solr)。

CREATE TABLE events (
    unique_serial bigint,
    time_period int,
    event_id timeuuid,
    search_field_1 int,
    search_field_2 double,
    search_field_3 double,
    summary text,
    data text,
    PRIMARY KEY((unique_serial, time_period), event_id)
) WITH CLUSTERING ORDER BY (event_id DESC);

我的solr架构如下所示:

<schema name="events" version="1.1">
    <types>
        <fieldType name="string" class="solr.StrField"/>
        <fieldType name="long" class="solr.LongField" />
        <fieldType name="double" class="solr.DoubleField" /> 
        <fieldType name="int" class="solr.IntField" />
        <fieldType name="text" class="solr.TextField">
            <analyzer>
                 <tokenizer class="solr.StandardTokenizerFactory"/>
            </analyzer>
        </fieldType>
        <fieldType name="uuid" class="solr.UUIDField" />
    </types>
    <fields>
    <field name="unique_serial" type="long" indexed="true"  stored="true"/>
        <field name="time_period" type="int" indexed="false" stored="true" />
        <field name="event_id" type="uuid" indexed="true" stored="true" />
    <field name="search_field_1" type="int" indexed="true"  stored="true"/>
    <field name="search_field_2" type="double" indexed="true"  stored="true"/>
    <field name="search_field_3" type="double" indexed="true"  stored="true"/>
        <field name="summary" type="text" indexed="true" stored="true" />
    </fields>

    <defaultSearchField>summary</defaultSearchField>
    <uniqueKey>(unique_serial,time_period,event_id)</uniqueKey>
</schema>

当我尝试创建solr核心时,我收到此错误:

Caused by: java.lang.IllegalStateException: Mismatch between Solr key field event_id with type uuid{class=org.apache.solr.schema.UUIDField,analyzer=org.apache.solr.schema.FieldType$DefaultAnalyzer,args={class=solr.UUIDField}} and Cassandra key alias event_id with type timeuuid

如果我将event_id更改为UUID然后它可以工作,但我想保持event_id排序的行。根据文档,如果UUID都是版本1,UUID将执行此操作,但我喜欢timeuuid如何明确时间的重要性并强制执行版本1.

也许我误解了datastax文档,但我认为timeuuid得到了支持(http://www.datastax.com/documentation/datastax_enterprise/4.0/datastax_enterprise/srch/srchSolrType.html

看起来像是由“CLUSTERING ORDER BY”指令引起的错误,请在没有它​​的情况下尝试让我们知道。
