Summary: Delta indexing with child documents with help of
cacheImpl="SortedMapBackedCache"
Key: SOLR-9774
URL: https://issues.apache.org/jira/browse/SOLR-9774
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: contrib - DataImportHandler, Data-driven Schema
Affects Versions: 6.1
Reporter: Aniket Khare
Hi,
I am using solr DIH for indexing the Parent-Child relation data and using
cacheImpl="SortedMapBackedCache".
For Full data indexinf I am using command clean="true" and for delta I am using
command full-import and clean="false".
So the same queries are being executed for fulland delta and indexing working
properly.
The issue which we are facing is where for a perticuler parent document, there
not a single child document and we are adding new child document.
Following are the steps to reproduce the issue.
1. Add Child document to an existing parent document which is not having empty
child document.
2. Once the child document is added with delta indexing, try to modify the
parent document and run delta indexing again
3. After the delta indexing is completed, I can see the modified child
documents showing in Solr DIH page in debug mode. But the it is not getting
updated in Solr collection.
I am using data config as below as below.
<document name="User">
<entity name="Parent" dataSource="DS1" pk="id" query="[SP_GetData]
'${dih.last_index_time}','${dataimporter.request.clean}'">
<field column="id" name="id"/>
<field column="FirstName" name="FirstName"/>
<field column="LastName" name="LastName"/>
<entity name="R" dataSource="DS1" query="[SP_GetDataRole]
'${dih.last_index_time}','${dataimporter.request.clean}'"
cacheKey="id" cacheLookup="Parent.id" processor="SqlEntityProcessor"
cacheImpl="SortedMapBackedCache">
<field column="RID" name="RID"/>
<field column="RNAME" name="RID"/>
</entity>
<entity name="P" dataSource="DS2" query="[SP_GetDataTest]
'${dih.last_index_time}','${dataimporter.request.clean}'"
cacheKey="PID" cacheLookup="Parent.id" processor="SqlEntityProcessor"
cacheImpl="SortedMapBackedCache" child="true">
<field column="id" name="id"/>
<field column="PNAME" name="PNAME"/>
</entity>
</entity>
</document>
