[infinispan-issues] [JBoss JIRA] (ISPN-4708) Make DirectoryImplementor#deleteFile apply changes asynchronously

Make DirectoryImplementor#deleteFile apply changes asynchronously ----------------------------------------------------------------- Key: ISPN-4708 URL: https://issues.jboss.org/browse/ISPN-4708 Project: Infinispan Issue Type: Enhancement Components: Lucene Directory Reporter: Sanne Grinovero Assignee: Gustavo Fernandes Fix For: 7.0.0.CR2 Looks like the {{deleteFile}} operation is the main responsible component for the latency generated by writing to the Lucene Directory, but this operation could be processed asynchronously by a background thread. Configurtion API {{org.infinispan.lucene.directory.BuildContext}} could allow for an optional Executor to be passed for this purpose, and if there isn't we keep current behaviour for running it synchronously. The tricky part I guess is making sure that the tests, which verify written consistency -including delete operations - are refactored to be able to deal with the fact that delete operations will happen eventually.
