Rupert Westenthaler resolved STANBOL-1447.
------------------------------------------
Resolution: Fixed
> Improve FST Corpus handling and updates
> ---------------------------------------
>
> Key: STANBOL-1447
> URL: https://issues.apache.org/jira/browse/STANBOL-1447
> Project: Stanbol
> Issue Type: Improvement
> Components: Enhancement Engines
> Affects Versions: 0.12.0
> Reporter: Rupert Westenthaler
> Assignee: Rupert Westenthaler
> Priority: Minor
> Fix For: 1.0.0, 0.12.1
>
>
> The Lucene FST linking engine manages FST corpora that need to be rebuild
> when the Solr Core has updates. Because of the every FST corpora knows the
> Solr version it was built for.
> Currently it is checked on every call the the Lucene FST linking engine if
> the version of the FST corpora is still in sync with the version of the the
> SolrCore. If not the re-creation of the FST corpora is enqueued. However
> until the conpletion of this task enhancement requests are processed using an
> older version of the FST corpora.
> The initial idea of this was to prevent long waits for huge indexes (e.g. for
> DBPedia the creation of the FST corpara takes more as a minute). But in
> reality FST corpora are typically built in seconds.
> That means that in most cases it would be better to wait for the re-creation
> of the corpus rather than using an outdated version.
> This issue will change the FST corpora management to use Futures so that
> components can wait for corpora to be created. The code will also use a
> reasonable wait time for corpora to be built.
