create DirectoryManager to handle different I/O aspects of an index ------------------------------------------------------------------- Key: HSEARCH-758 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-758 Project: Hibernate Search Issue Type: Improvement Reporter: Sanne Grinovero Assignee: Sanne Grinovero Fix For: 4.0.0.Alpha1 Near-Real-Time Lucene usage requires a coupling between the indexwriter and the indexreaders being used for searches. Also to make other features simpler we need to manage indexwriters and indexreaders in a more integrated form (Infinispan). refactor : DirectoryProvider * make a "DirectoryManager" instead, which is able to provide factories for both IndexReader an IndexWriters * add utility methods like "getName()" o (wish I had that in some cases to provide better error messages) * Instead of trying to foresee all needed methods, the extension point should not be the DirectoryManager interface directly, but have people plug in different aspects. * This is needed to eventually support: o Instantiated indexes - HSEARCH-336 o make good use of all new so called "Near-Real-Time" Lucene improvements by having IndexReader and IndexWriter possibly generated by the same service o reuse the JGroups channel used by the Infinispan Directory as transport for a backend (again, the two components need to interact)
