[hibernate-issues] [Hibernate-JIRA] Created: (HSEARCH-626) Allow MassIndexer to work in parallel of regular indexing / querying

Allow MassIndexer to work in parallel of regular indexing / querying -------------------------------------------------------------------- Key: HSEARCH-626 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-626 Project: Hibernate Search Issue Type: New Feature Components: massindexer Reporter: Emmanuel Bernard Some people want to use mass indexer to reindex live some data. This is problematic today as MassIndexer expects to work alone / offline. I can see at least one approach: - copy the index to a new Directory before mass indexing (or if exclusive, start with a new Directory while keeping the old Directory in place - the current directory needs to become read-only - all index update (on the entity) requests should be queued up for after massIndexer is done - MassIndexer swaps the current and the new directory - indexing and querying resume as normal Note that we need to work on a different directory because mass indexer does delete all entries of an entity before starting the reindexing process. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
