Overview

KitaroDB was an embedded NoSQL store from Synergex, the company behind the Synergy DBL language and its ISAM engine. It ran in-process on Windows Store (WinRT), Windows Phone 8 and Win32 apps and exposed both a key-value API and 'intrusive key' records whose keys are segments of the stored data, callable from C#, VB, C++, C and HTML5/JavaScript Windows apps. It was a free download and claimed tens of thousands of operations per second on devices. Version 2.0 (May 2013) added Windows Phone 8, and the last NuGet release, 2.3.1, appeared in August 2015. With Microsoft's mobile platforms gone the product disappeared, and kitarodb.com is now a domain for sale.

Partly. KitaroDB offers limited ACID guarantees (for example, single-record or single-partition transactions), with strong consistency.

Does KitaroDB scale horizontally?

KitaroDB does not scale horizontally; it runs on a single node, so you scale it up rather than out. It is comfortable at small scale (≤ 100 GB).

How can I run KitaroDB?

You can embed it in your application.

What is KitaroDB best for?

KitaroDB is a strong fit for maintaining old Windows Store or Windows Phone apps that used it and historical reference for mobile embedded stores. Think twice for any new application.

Common alternatives to KitaroDB include SQLite, LiteDB, Realm (Atlas Device SDK), ObjectBox and MarcelloDB. The right choice depends on your workload, scale and hosting; WhichDB's smart match ranks them against your requirements.
