wallets

Components

The application has two components:

postgres - database.
wallets - HTTP server.

1. postgres

The database contains two tables wallets and operations.

wallets contains wallet name and balance.
operations contains deposit and withdrawal operations.

Read migrations for details.

I decided to use sql.LevelSerializable for transactions. This simplifies life on the stage of development. In the future it will be possible to try to optimize.

2. wallets

The wallets component can be run in multiple instances.
It serves four endpoints:

POST /wallets - Add wallet.
POST /wallets/deposit - Top up wallet.
POST /wallets/transfer - Transfer money.
GET /wallets/operations - Get wallet operations.

Read api/v1/swagger.yaml for details.
