Metadata Structure Overview

Metadata：

Reference：

Note: In reality, the reference paths are hashed.

Defining MetadataStore tables using DynamoDB

Metadata：

Key	Attributes	Type	Description
PK	id	string	Unique ID (eg. UUID)
GSIPK1	parent_id	string	ID of the parent directory
	name	string	Name (eg. report.pdf)
	type	string	File system entry type (eg. File or Directory)
	size	number	File size (eg. 512)
	modify	string	File modify time (eg. ISO 8601)
	version	number	Version number for optimistic lock (eg. 1)

Reference：

Key	Attributes	Type	Description
PK	id	string	Unique ID (eg. hashed path)
	entries	map	key(hashed path): value(metadata id)
	version	number	Version number for optimistic lock (eg. 1)

PhysicalStorage specifications using S3

# S3 Key (Metadata#id)
$bucket_name/$UUID

Development

Starting Docker Compose:

docker-compose up --force-recreate --build --abort-on-container-exit

Initialize DynamoDB(dynamodb-local):

docker-compose run dynamodb-init

Initialize S3(minio):

docker-compose run s3-init

Run Go Application:

env AWS_ACCESS_KEY_ID="AKIAIOSFODNN7EXAMPLE" AWS_SECRET_ACCESS_KEY="wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" AWS_REGION="us-east-1" go run main.go --port=8080 --dynamodb-url=http://localhost:18070 --s3-url=http://localhost:19010
