/**
 * Defines the service contract for the Executor which we'll use in
 * combination with the Infinispan Lucene Directory, as this provides
 * an option to execute delete operations in background.
 * It is important to run delete operations in background as while these
 * are simple from a computational point of view, they will introduce a
 * significant delay on write operations when Infinispan is running in
 * clustered mode.
 * This is implemented as a Service so that integrations can inject a
 * different managed threadpool, and we can share the same executor
 * among multiple IndexManagers.
