> Database as a lucene index target
> ---------------------------------
>
> Key: LUCENE-487
> URL: http://issues.apache.org/jira/browse/LUCENE-487
> Project: Lucene - Java
> Issue Type: New Feature
> Components: Store
> Affects Versions: 1.9
> Environment: MySql (version 4.1 an up), Oracle (version 8.1.7 and up)
> Reporter: Amir Kibbar
> Priority: Minor
> Attachments: files.zip
>
>
> I've written an extension for the Directory object called DBDirectory, that
> allows you to read and write a Lucene index to a database instead of a file
> system.
> This is done using blobs. Each blob represents a "file". Also, each blob has
> a name which is equivalent to the filename and a prefix, which is equivalent
> to a directory on a file system. This allows you to create multiple Lucene
> indexes in a single database schema.
> The solution uses two tables:
> LUCENE_INDEX - which holds the index files as blobs
> LUCENE_LOCK - holds the different locks
> Attached is my proposed solution. This solution is still very basic, but it
> does the job.
> The solution supports Oracle and mysql
> To use this solution:
> 1. Place the files:
> - DBDirectory in src/java/org/apache/lucene/store
> - TestDBIndex in src/test/org/apache/lucene/index
> - objects-mysql.sql in src/db
> - objects-oracle.sql in src/db
> 2. Edit the parameters for the database connection in TestDBIndex
> 3. Create the database tables using the objects-mysql.sql script (assuming
> you're using mysql)
> 4. Build Lucene
> 5. Run TestDBIndex with the database driver in the classpath
> I've tested the solution on mysql, but it *should* work on Oracle, I will
> test that in a few days.
