MongoDB data types

String: You know what it is!

Integer: This type is used to store a numerical value. Integer can be 32 bit or 64 bit depending upon your server.

Boolean: True/False

Double: This type is used to store floating point values.

Arrays: [list, of, elements]

Timestamp: This can be handy for recording when a document has been modified or added.

Object: This datatype is used for embedded documents. Like {"images": {"a": "ali", "b": "reza"}}

Null: This type is used to store a Null value.

Date: This datatype is used to store the current date or time in UNIX time format. You can specify your own date time by creating object of Date and passing day, month, year into it.

Object ID: This datatype is used to store the document’s ID.

There are some more like Code, Regex and so which is used less than other data types.

Minio is an object storage server that is compatible with Amazon S3. You can run your own object storage server using docker:
- https://docs.minio.io/docs/minio-docker-quickstart-guide

And you can use its Python SDK in order to talk to its endpoint API:
- https://github.com/minio/minio-py

It's usage is very simple and elegant. If you are unfamiliar with object storage read more here:

How to upload file into Amazon object storage using boto3?

pip install boto3

Now you just need the region, endpoint and access key, secret key which you would be given after purchase:

client = session.client('s3',
                         region_name=YOUR_REGION,
                         endpoint_url=YOUR_HOST,
                         aws_access_key_id=YOUR_ACCESS_KEY,
                         aws_secret_access_key=YOUR_SECRET_KEY)

 client.upload_file(file_path,  # Path to local file
                    obj_config['spacename'],  # Name of Space
                    'YOUR_FILE_NAME.txt',  # Name for remote file
                     ExtraArgs={"Metadata": {'user-id': USER_ID} })  # metadata

NOTE: in the name of the file you can pass / like my/file/here.txt. Now it will create directory (virtually) in the remote object storage.
