[jira] Created: (LUCENE-1030) "Read-only" IndexReaders
"Read-only" IndexReaders
------------------------
Key: LUCENE-1030
URL: https://issues.apache.org/jira/browse/LUCENE-1030
Project: Lucene - Java
Issue Type: Improvement
Components: Index
Reporter: Michael Busch
Priority: Minor
IndexReaders are able to perform certain write operations on an index (setNorm(), deleteDocument()). This makes issues like LUCENE-743 more complicated and also duplicate code for acquiring locks and write transactions is necessary.
Therefore we should make IndexReaders "read-only" in the future. However, we have to find a good solution to support setting norms and deleting documents by docid with the IndexWriter. See related discussions in LUCENE-743 and http://www.gossamer-threads.com/lists/lucene/java-dev/52017.
