+// async log helper :
+// Process logs asynchronously using a back thread.
+//
+// If the internal queue of log messages reaches its max size,
+// then the client call will block until there is more room.
+//
+// If the back thread throws during logging, a spdlog::spdlog_ex exception
+// will be thrown in client's thread when tries to log the next message
