The API supports object store type datasources (S3) and allows for easy retrieval and upload of objects.
Note
Get the datasource from the client:
from domino.data_sources import DataSourceClient
s3_dev = DataSourceClient().get_datasource("s3-dev")You can list objects available in the datasource. You can also specify a prefix:
objects = s3_dev.list_objects()
objects_under_path = s3_dev.list_objects("path_prefix")You can get object content, without having to create object entities, by using the datasource API and specifying the Object key name:
# Get content as binary
content = s3_dev.get("key")
# Download content to file
s3_dev.download_file("key", "./path/to/local/file")
# Download content to file-like object
f = io.BytesIO()
s3_dev.download_fileobj("key", f)You can also get the datasource entity content from an object entity:
# Key object
my_key = s3_dev.Object("key")
# Get content as binary
content = my_key.get()
# Download content to file
my_key.download_file("./path/to/local/file")
# Download content to file-like object
f = io.BytesIO()
my_key.download_fileobj(f)Similar to the read/get APIs, you can also write data to a specific object key. From the datasource:
# Put binary content to given object key
s3_dev.put("key", b"content")
# Upload file content to specified object key
s3_dev.upload_file("key", "./path/to/local/file")
# Upload file-like content to specified object key
f = io.BytesIO(b"content")
s3_dev.upload_fileobj("key", f)You can also write from the object entity.
# Key object
my_key = s3_dev.Object("key")
# Put content as binary
my_key.put(b"content")
# Upload content from file
my_key.upload_file("./path/to/local/file")
# Upload content from file-like object
f = io.BytesIO()
my_key.upload_fileobj(f)
