Accepted

|
|
## Context
|
|
|
|
- Multiple accounts login at the same time in the same browser. The accounts will use the same database (`IndexDatabase`).
|
|
|
|
## Decision
|
|
|
|
- Use unique parameters (`AccountId`, `UserName`, `ObjectId(MailboxId/EmailId/StateType`) to form a unique `key` for storage (called `TupleKey`).
|
|
- TupleKey has the format: `ObjectId | AccountId | User`;
|
|
- `HiveDatabase` includes many `Box`. Each box is a `Map<Key, Object>` with `key=TupleKey`.
|
|
|
|
## Consequences
|
|
|
|
- The correct `mailbox` and `email` lists are obtained for each account
