Otis Gospodnetic updated LUCENE-487: ------------------------------------ Comment: was deleted > 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. > Amir -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
