        }
        if (SnapshotService.getSkipStateStorageThreadLocal().get() == null || !SnapshotService.getSkipStateStorageThreadLocal().get()) {
            Map<String, StateHolder> stateHolderMap = getSnapshotService().getStateHolderMap(SiddhiConstants.PARTITION_ID_DEFAULT, SiddhiConstants.PARTITION_ID_DEFAULT);
            stateHolderMap.put(name + "-" + idGenerator.createNewId(), stateHolder);
        }
        return stateHolder;
    } else {
