Data Model

Key/Value

BoJack's data model relies on a key/value store which maps string keys to string array values.

Concurrency Control

BoJack does not provide any kind of concurrency control. Concurrent client requests are handled by the Crystal language's concurrent Channel class.

Query Interface

Command-line / Shell

Bojack provides a standard command-line interface for starting the server and connecting clients.

Foreign Keys

Not Supported

As BoJack is a key-value store, SQL joins are not supported.
