public static KVOperation createDeleteList(final List<byte[]> keys) {
        Requires.requireNonNull(keys, "keys");
        Requires.requireTrue(!keys.isEmpty(), "keys is empty");
        return new KVOperation(BytesUtil.EMPTY_BYTES, BytesUtil.EMPTY_BYTES, keys, DELETE_LIST);
    }
The best practice is to call this method only once
and keep a copy of it yourself.
