   ```java
   // Multiple of these callables can be submitted at the same time, but the callables themselves
   // are executed serially, so double check that it hasn't already been populated.
   if (!watchedConfigs.containsKey(key)) {
     byte[] value = dbConnector.lookup(configTable, "name", "payload", key);
     ConfigHolder<T> holder = new ConfigHolder<T>(value, serde);
     watchedConfigs.put(key, holder);
   }
   ```
