Solr-索引MySQL数据库

Question

每天添加新表时，是否有可能索引一个完整的数据库而不在data-config.xml中明确提及表名，而我每天都不能更改data-config.xml来添加新表。

Haven table names based on the date smells like there is something wrong in your Design. But given this requirement in your question you can add Data to your solr server without telling you have a DB. You just have to make sure you hav a unique ID for the data record in you solr Server with whom you can identify the corresponding record in your DB, something like abcd_2011_03_19.uniqueid . You can post the data to solr in Java in solrj or just plain xml or json.

Example:

--------------
| User Input |
--------------
      |post
      V
-----------------------------------
| My Backend (generate unique id) |
-----------------------------------
  |post(sql)       |post (e.g. solrj)
  V                V
------           --------
| DB |           | solr |
------           --------
