While it is not clear on what you are trying to store with multi-dimensional arrays, since you are asking for Streams, perhaps you could use a Blob data type. 尽管您不清楚要使用多维数组存储什么内容，但是由于您要使用Streams，也许可以使用Blob数据类型。 This means, you can serialize an object and store the resulting bytes to a field of type Blob. 这意味着，您可以序列化一个对象并将结果字节存储到Blob类型的字段中。

Like Sai said you could store it as a Blob. 就像Sai所说的，您可以将其存储为Blob。 But you wouldn't be able to query it. 但是您将无法查询它。 Would it be possible to convert the data to a hashmap or does it need to be a 2d-array? 是否可以将数据转换为哈希图，或者是否需要为二维数组？
If you don't need to query it I'd just go for the blob. 如果您不需要查询它，那我就去看看。
