How I can use big data with scanpy?

Thanks for developing scanpy.
I want to run scanpy on kaggle or Colab but they have 30gb and 12gb of RAM, respectively. When I read my data with “read_h5ad()”, Colab is crash and 25gb of Keggle’s RAM is occupied and when I want use “”, Kaggle is crashed. When I want to read data by “backed = ‘r’ or ‘r+’”, “” give me error. Can you help me How I can load this data withoud crash in Colab?
