---------------------------------------
> Better default gora-sql-mapping.xml with larger field sizes for MySQL

> Key: NUTCH-1497
> URL: https://issues.apache.org/jira/browse/NUTCH-1497
> Project: Nutch
> Issue Type: Improvement
> Components: storage
> Affects Versions: 2.2
> Environment: MySQL Backend
> Reporter: James Sullivan
> Priority: Minor
> Labels: MySQL
> Fix For: 2.3

> Attachments: gora-mysql-mapping-patch, gora-mysql-mapping.xml,

> The current generic default gora-sql-mapping.xml has field sizes that are too
> small in almost all situations when used with MySQL. I have included a
> mapping which will work better for MySQL (takes slightly more space but will
> be able to handle larger fields necessary for real world use). Includes patch
> from Nutch-1490 and resolves the non-Unicode part of Nutch-1473. I believe it
> is not possible to use the same gora-sql-mapping for both hsqldb and MySQL
> without a significantly degraded lowest common denominator resulting. Should
> the user manually rename the attached file to gora-sql-mapping.xml or is
> there a way to have Nutch automatically use it when MySQL is selected in
> other configurations (Ivy.xml or gora.properties)?
