Subject [jira] Commented: (SOLR-469) Data Import RequestHandler
Date Tue, 22 Apr 2008 13:42:30 GMT

    [ https://issues.apache.org/jira/browse/SOLR-469?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12591300#action_12591300

Grant Ingersoll commented on SOLR-469:
--------------------------------------




I was just thinking as an option.  How does it limit?  A single SQL  
can join across tables.  I will try to update the patch w/ my merges  
when I get a breather.  I have the case where I can send in something  
like:

select col1 as field1, col2 as field2, ... from table1, ... where ...;

and it goes and runs that SQL against the specified connection.   
Basically, any valid SQL select statement can be sent in.

Actually, I can send in multiple SQL statements as well, or just  
specify the table, or the table and certain columns.

> 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)
