问题描述
我正在尝试将数据从Mongodb导入到Solr6.0.完全导入正在正确执行,但增量导入无法正常工作.当我执行增量导入时,我得到以下结果.
I am trying to import data from Mongodb to Solr6.0. Full import is executing properly but delta import is not working. When I execute delta import I get below result.
我的数据配置文件查询如下
My data config file queries are as below
query=""
deltaQuery="db.getCollection('customer').find({'jDate':{$gt:'${dih.last_index_time}'}},{'_id' :1});"
deltaImportQuery="db.getCollection('customer').find({'_id':'${dataimporter.delta.id}'})"
整个data-config.xml
the whole data-config.xml
<?xml version="1.0"?>
<dataConfig>
<dataSource name="MyMongo" type="MongoDataSource" database="test_db" />
<document name="import">
<!-- if query="" then it imports everything -->
<entity processor="MongoEntityProcessor"
query=""
deltaQuery="db.getCollection('customer').find({'jDate':{$gt: '${dih.last_index_time}'}},{'_id' :1});"
deltaImportQuery="db.getCollection('customer').find({'_id':'${dataimporter.delta.id}'})"
collection="customer"
datasource="MyMongo"
transformer="MongoMapperTransformer" name="sample_entity">
<!-- If mongoField name and the field declared in schema.xml are same than no need to declare below.
If not same than you have to refer the mongoField to field in schema.xml
( Ex: mongoField="EmpNumber" to name="EmployeeNumber"). -->
<field column="_id" name="id"/>
<field column="CustID" name="CustID" mongoField="CustID"/>
<field column="CustName" name="CustName" mongoField="CustName"/>
<field column="jDate" name="jDate" mongoField="jDate"/>
<field column="dob" name="dob" mongoField="dob"/>
</entity>
</document>
</dataConfig>
query=""
deltaQuery="db.getCollection('customer').find({'jDate':{$gt: new Date(1480581295000)}},{'_id' :1});"
deltaImportQuery="db.getCollection('customer').find({'_id':ObjectId('34234234dfsd34534524234ee')})"
query=""
deltaQuery="{'jDate':{$gt: new Date(1480581295000)}}"
deltaImportQuery="{'_id':ObjectId(34234234dfsd34534524234ee)}"
任何人,请可以.
推荐答案
可以尝试
deltaQuery as db.getCollection('customer').find({'jDate':{$gt:**ISODate(**'${dih.last_index_time}'**)**}},{'_id' :1});
