AmnesiaDB is a simple key/value storage engine developed with a single purpose: studying internal aspects of a database. It's supposed to be an LSM-Tree with some specific types being implemented using B+-Trees.

• SET: Implemented using B+-Trees
• STRING: Plain values stored by commands like set somekey somevalue

bundle install

bundle exec rspec

./amnesia-cli dbname.db

Once you are in the prompt you can execute the following commands: get, set, and delete.

> set firstName Mabel
> set lastName Pines

for deleting:

> delete firstName

for retrieving:

> get lastName
Pines
