Solr在复制的MySQL数据库上搜索

Question

I want to create a database web publisher.

Solr search functionnalities suit perfectly to my needs (faceted search, full text search, etc...).

My problem is that I need data to be synchronised on the net.

I read that MySQL database have to be imported in Solr.

I plan to work with one source MSSQL database, replicated on a MySQL database on a web server. I need to use Solr on this database.

Is there a solution so that the changes on the replicated SQL database can be automatically echoed on the Solr index? I don't want to import the whole database each time it is modified, it would make my product complicated to use.

Thank you.

Answer 1

you don't need to index the full db each time, that is what Delta import is for. You just configure it to import deltas at the times you need.

Answer 2

You can use DataImportScheduler to keep your data synchronized. That's the most common way to keep Solr index in sync.

There are other ways, you could setup a trigger in your db to fire Solr's REST service that would reflect changes for all inserted/updated/deleted documents.

Also, since db is (commonly) used to handle some application, you could setup a Filter (javax.servlet for Java web apps) to intercept requests and push them to Solr before they even reach database.
