Default AdvancedCacheLoader#publishEntries can hang with more than 2048 entries ------------------------------------------------------------------------------- Key: ISPN-9777 URL: https://issues.jboss.org/browse/ISPN-9777 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Affects Versions: 9.3.0.Final Reporter: William Burns Assignee: William Burns Priority: Major Fix For: 10.0.0.Alpha2 The default method for AdvancedCacheLoader#publishEntries relies on the invocation of the process method. This uses the PersistenceManagerCloseableSupplier to handle this. Unfortunately it uses a WithinThreadExecutor, which actually can cause the process method to deadlock with a single thread as it can fill up the queue of 2048 elements. We should instead use a single threaded executor which would allow the loading of elements and retrieval in parallel on 2 different threads.
