------------------------------------

Hi-  thanks for posting this.

I have not had a chance to look at this in depth, but a couple things jump out 
at me.

1.  It looks like the model here is to treat "data-config.xml" as the master 
and generate schema,xml from that.  To me this seems a bit strange and 
difficult to support long term.  In my view, "schema.xml" should always be the 
place to define fields and indexing properties.  "data-config.xml" should just 
be the place that maps SQL to the schema.

2. why not just use the standard copyField stuff rather then rolling your own?
{code:xml}
        <field name="text">
            <copyFrom>cat</copyFrom>
            <copyFrom>name</copyFrom>
            <copyFrom>manu</copyFrom>
            <copyFrom>features</copyFrom>
        </field>
{code}

> We need a RequestHandler Which can import data from a DB or other dataSources 
> into the Solr index .Think of it as an advanced form of SqlUpload Plugin 
> (SOLR-103).
> The way it works is as follows.
>     * Provide a configuration file (xml) to the Handler which takes in the 
> necessary SQL queries and mappings to a solr schema
>           - It also takes in a properties file for the data source 
> configuraution
>     * Given the configuration it can also generate the solr schema.xml
>     * It is registered as a RequestHandler which can take two commands 
> do-full-import, do-delta-import
>           -  do-full-import - dumps all the data from the Database into the 
> index (based on the SQL query in configuration)
>           - do-delta-import - dumps all the data that has changed since last 
> import. (We assume a modified-timestamp column in tables)
>     * It provides a admin page
>           - where we can schedule it to be run automatically at regular 
> intervals
>           - It shows the status of the Handler (idle, full-import, 
> delta-import)
