https://issues.apache.org/jira/browse/SOLR-1499
This is a patch (not committed) that queries a Solr instance and returns
the values as a DIH document. This allows you to do a sort query to
Solr, ask for the first result, and continue indexing after that. Scary,
but it works.

Currently DIH delta import uses the SQL query of type "select id from

What I need is some field like ${dataimporter.last_primary_key}
wiki.apache.org/solr/DataImportHandler
I am thinking of storing the last primary key externally and calling the
delta-import with a parameter and using
${dataimporter.request.last_primary_key} but that seems like a very
brittle approach

Of course you can store whatever you want in a solr index. And if you
store an integer as a Solr 1.4 "int" type, you can certainly query for
all documents that have greater than some specified integer in a field.
You can't use SQL to query Solr though.
I'm not sure what you're really asking?

Hi,
I have a table that I want to index, and the table has no datetime
stamp. However, the table is append only so the primary key can only
go
up. Is it possible to store the last primary key, and use some delta
query="select id where id>${last_id_value}"
Cheers,
David
