Add utitily class to manage NRT reopening -----------------------------------------
Key: LUCENE-2955 URL: https://issues.apache.org/jira/browse/LUCENE-2955 Project: Lucene - Java Issue Type: Improvement Components: Index Reporter: Michael McCandless Assignee: Michael McCandless Fix For: 3.2, 4.0 I created a simple class, NRTManager, that tries to abstract away some of the reopen logic when using NRT readers. You give it your IW, tell it min and max nanoseconds staleness you can tolerate, and it privately runs a reopen thread to periodically reopen the searcher. It subsumes the SearcherManager from LIA2. Besides running the reopen thread, it also adds the notion of a "generation" containing changes you've made. So eg it has addDocument, returning a long. You can then take that long value and pass it back to the getSearcher method and getSearcher will return a searcher that reflects the changes made in that generation. This gives your app the freedom to force "immediate" consistency (ie wait for the reopen) only for those searches that require it, like a verifier that adds a doc and then immediately searches for it, but also use "eventual consistency" for other searches. I want to also add support for the new "applyDeletions" option when pulling an NRT reader. Also, this is very new and I'm sure buggy -- the concurrency is either wrong over overly-locking. But it's a start... -- This message is automatically generated by JIRA.
