Question

我在使用MySQL数据库进行Solr delta-import时遇到问题。我能够完全导入没问题。当我尝试进行delta-import时，它会导入已更改的记录（如预期的那样），但会清除索引的其余部分，以便只有更新的记录在索引中。日志中没有错误。我在配置中遗漏了什么吗？在Ubuntu服务器上运行Solr 5.4并使用管理UI。

<dataConfig>
    <dataSource driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/ibnet" user="xxxx" password="xxxxx" />
    <document>
    <entity name="profile" pk="profile.id" query="
        SELECT 
            profile.id AS id,
            profile.profile_status AS profile_status,
            //
            // Other fields
            //
            linkedProfile.org_name AS linked_org_name,
            linkedProfile.org_city AS linked_org_city,
            linkedProfile.org_st_prov_reg AS linked_org_st_prov_reg,
            linkedProfile.org_country AS linked_org_country
        FROM profile AS profile
        LEFT JOIN profile AS linkedProfile ON linkedProfile.id = profile.linked_id" 
        deltaImportQuery="
            SELECT 
                profile.id AS id,
                profile.profile_status AS profile_status,
                //
                // Other fields
                //
                linkedProfile.org_name AS linked_org_name,
                linkedProfile.org_city AS linked_org_city,
                linkedProfile.org_st_prov_reg AS linked_org_st_prov_reg,
                linkedProfile.org_country AS linked_org_country
            FROM profile AS profile
            LEFT JOIN profile AS linkedProfile ON linkedProfile.id = profile.linked_id
            WHERE profile.id = '${dih.delta.id}'"
        deltaQuery="SELECT profile.id FROM profile WHERE last_modified > '${dih.last_index_time}'"
        onError="skip" >
    </entity>
</document>

编辑：我已将dih.delta.id更改为dataimporter.delta.id，并将其更改为last_index_time，但这并未改变结果。

以下是回复：

Answer 1

在solr admin中 - ＆gt;你的核心 - ＆gt; dataimport，有一个Clean选项，如果选中则会在导入之前先清理数据（对于完全导入和delta导入）。

另一个提示是，solr DIH总是使用UTC作为导入时间戳，那么你的时区是多少？首先将数据库中的datetime列转换为utc，然后再将其与dih.last_index_time进行比较。

Solr delta-import删除索引
