[jira] Updated: (LUCENE-1026) Provide a simple way to concurrently
access a Lucene index from multiple threads
[ https://issues.apache.org/jira/browse/LUCENE-1026?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mark Miller updated LUCENE-1026:
--------------------------------
Attachment: IndexAccessor-02.04.2008.zip
Putting up a new rev and hoping for some feedback.
Certainly usable, but there are still some things I would like to fine tune and improve.
This is a big improvement over the last patch.
- When creating an IndexAccessor you can now optionally pass a query and sort fields to warm new Readers before they are put into production.
- Releasing a Writer never blocks for a reopen now - so after adding a doc it may be a second or two before its visible to new Searchers
- Removed sync blocks around IndexAccessor retrievals makes getting an accessor much faster.
- Fixed the Reading Reader reopen method.

> Key: LUCENE-1026
> URL: https://issues.apache.org/jira/browse/LUCENE-1026
> Project: Lucene - Java
> Issue Type: New Feature
> Components: Index, Search
> Reporter: Mark Miller
> Priority: Minor
> Attachments: DefaultIndexAccessor.java, DefaultMultiIndexAccessor.java, IndexAccessor-02.04.2008.zip, IndexAccessor-1.26.2008.zip, IndexAccessor.java, IndexAccessor.zip, IndexAccessorFactory.java, MultiIndexAccessor.java, shai-IndexAccessor-2.zip, shai-IndexAccessor.zip, shai-IndexAccessor3.zip, SimpleSearchServer.java, StopWatch.java, TestIndexAccessor.java
>
>
> For building interactive indexes accessed through a network/internet (multiple threads).
> This builds upon the LuceneIndexAccessor patch. That patch was not very newbie friendly and did not properly handle MultiSearchers (or at the least made it easy to get into trouble).
> This patch simplifies things and provides out of the box support for sharing the IndexAccessors across threads. There is also a simple test class and example SearchServer to get you started.
> Future revisions will be zipped.
> Works pretty solid as is, but could use the ability to warm new Searchers.
