Unify configuration settings for batch and transaction indexwriter settings --------------------------------------------------------------------------- Key: HSEARCH-743 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-743 Project: Hibernate Search Issue Type: Remove Feature Components: documentation, engine Reporter: Sanne Grinovero Assignee: Sanne Grinovero Fix For: 4.0 In the Hibernate Search 3.0 era a new IndexWriter would have been opened for each "List of Work" (set of index operations) to be performed: each index change would acquire the index lock, each changeset could not be applied in parallel. So to be as quick as possible with these frequent and small index changes, you'd likely wanted an "interactive IndexWriter configuration", significantly different than the settings being used for batch indexing: so Hibernate Search had two different sets of parameters which could be set. Since 3.1 the back-end became a bit better: updates to different indexes would be applied in parallel, but still for each changeset a new IW was opened and released. During 3.2 we introduced the massindexer which provides a new alternative to the batching use case, and also HSEARCH-327 which basically requires to never change the IndexWriter configuration during non-massindexer work: since then if this option is enabled we might be inconsistent about which options are being used - and definitely doesn't make much sense anymore. We agreed at that timeframe that it should be deprecated, and warnings have been logged since then on some options which really needed consistency - but it was never removed to keep compatibility: removing now for version 4.0
