----------------------------------------

Hi [~jbonofre],

The patch looks good, 
1. the values are hardcoded in log statements, its possible that in future we change the properties
without updating the log statements, it might just confuse the users.
{code}
+        kahaDB.setJournalMaxFileLength(32 * 1024 * 1024);
+        kahaDB.setCleanupInterval(2000);
+        kahaDB.setCheckpointInterval(2000);
+        kahaDB.setEnableIndexWriteAsync(true);
+        kahaDB.setConcurrentStoreAndDispatchQueues(true);
+        kahaDB.setConcurrentStoreAndDispatchTopics(true);
+        kahaDB.setIndexCacheSize(2000);
+        kahaDB.setIndexWriteBatchSize(2000);
+        LOGGER.debug("  Persistence adapter: (KahaDB)");
+        LOGGER.debug("    journalMaxFileLength: {}", maxFileLengthVal);
+        LOGGER.debug("    cleanupInterval: 2000");
+        LOGGER.debug("    checkpointInterval: 2000");
+        LOGGER.debug("    enableIndexWriteAsync: true");
+        LOGGER.debug("    concurrentStoreAndDispatchQueues: true");
+        LOGGER.debug("    concurrentStoreAndDispatchTopics: true");
+        LOGGER.debug("    indexWriteBatchSize: 2000");
+        LOGGER.debug("    indexCacheSize: 20000");
{code}
