Jonathan Lee commented on SOLR-469:
-----------------------------------
When using CachedSqlEntityProcessor, an NPE is thrown
(EntityProcessorBase.java:367) if a key value doesn't exist in the cached row
set. This change to EntityProcessorBase.java should fix that, or let me know
if I've missed something here!

> 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)
