SOLR数据导入处理程序跳过或忽略请求(SOLR data import handler skips or ignores request)

 我使用的是SOLR 6.0.0，我使用数据导入处理程序来处理从MySQL到SOLR的索引。 
 
 我在我的db-data-config.xml文件中有下面的查询 
 
<entity name="user" query="SELECT ID, A, B, C FROM `USER` U WHERE U.ID = '${dataimporter.request.id}' OR '' = '${dataimporter.request.id}'">
    <field column="A" name="A" ....
    .......
</entity>
 
 基本上，如果我通过ID，它只会索引该ID，否则会索引整个表。 
 
 现在问题是， 
 
 我有一个频繁的插入更新。 
 
 在第一次插入后，我发送请求到单个id / doc / row的索引，在几毫秒之后记录被更新，因此我再次发送索引相同id的请求。 现在看起来SOLR跳过第二个请求，因为我可以看到两个请求都去了，但更新后的数据不存在于SOLR中。 
 
 这也发生在非独特的项目上（不是相同的ID）。 我同时请求两个或三个数据导入，solr跳过/忽略第二个请求。 
 
 我用http方法请求它，发送下面的查询， 
 
http://localhost:8983/solr/user/dataimport?command=full-import&verbose=false&clean=false&commit=true&optimize=false&core=user&id=1

I am using SOLR 6.0.0 and I use data import handler to handle indexing from MySQL to SOLR.
 
I have below query in my db-data-config.xml file
 
<entity name="user" query="SELECT ID, A, B, C FROM `USER` U WHERE U.ID = '${dataimporter.request.id}' OR '' = '${dataimporter.request.id}'">
    <field column="A" name="A" ....
    .......
</entity>
 
Basically if i pass the id, it will index only that ID, otherwise it will index whole table.
 
Now Issue is,
 
I have a frequent insert update.
 
After first insert I send request to index of single id/doc/row, just after few millisecond the record gets updated so I send again the request to index same id. Now it seems SOLR skips the second request as I can see that both request went but the updated data is not present in the SOLR.
 
This happens with non unique items too (not same id). I request two or three data import at the same time and solr skips/ignores second request.
 
I request it with http method, sending following query,
 
http://localhost:8983/solr/user/dataimport?command=full-import&verbose=false&clean=false&commit=true&optimize=false&core=user&id=1
