Blue jet is a rare type of a lightning with a very blue colour with near-ultraviolet emission lines from neutral and ionized molecular nitrogen. It typically occurs in the lower levels of ionosphere at ~50km above the surface of the earth.

BlueJet is a modern Swift/Cocoa wrapper around Lightning Memory-Mapped Database Manager (LMDB). It fully utilises the multi-threaded access, transations and provides a simple enumeration interface for fetching subsets of the database. Key/Value pairs are using Swift's Encoder/Decoder protocol when dealing with the data.

With many data persistence options available for both Cocoa (Touch) and Server-side Swift BlueJet aims to be the simplest and fast Value Type store without the complexity of confusing query language, sub-classing your data models or large set of dependencies. This framework is designed to take any Swift's value type such as String, Int, Float and Data but also provide set of protocols to allow for custom type-to-Data conversion.

With the upcoming release of Swift 4, BlueJet will support struct encoder/decoder features making it even easier to store any data you use within your app.

LMDB is an incredibly fast key-value store written by Howard Chu for the OpenLDAP project. Given the nature of LDAP workloads the design of LMDB is read-optimised (but writes are super fast too!). This particular database allows for multiple databases within one environment which makes separating different data sets much easier to handle. It also allows for multiple processes to access a single database without locking it and supports transactions for making series of fail-safe reads/write routines.
