KeyDB vs Tarantool: What are the differences?

Introduction

In this article, we will compare the key differences between KeyDB and Tarantool, two popular database management systems.

  1. Architecture: KeyDB is an in-memory database that is compatible with Redis, whereas Tarantool is a multi-model database that supports both in-memory and disk-based storage. This architectural difference leads to variations in their performance and scalability.

  2. Data Modeling: KeyDB primarily focuses on key-value data modeling, similar to Redis. On the other hand, Tarantool supports a wider range of data models including key-value, document, graph, and more. This flexibility allows developers to choose the most suitable model based on their specific use case.

  3. Replication Techniques: KeyDB employs synchronous replication, where data is written to multiple nodes in a cluster before confirming the completion of an operation. In contrast, Tarantool uses both synchronous and asynchronous replication techniques, enabling greater flexibility in terms of consistency and high availability.

  4. Languages and APIs: KeyDB offers compatibility with the Redis API, meaning existing Redis clients and applications can seamlessly work with KeyDB. Tarantool, on the other hand, provides its own Lua-based API for data manipulation and retrieval, offering more fine-grained control and extensibility.

  5. Transactions and ACID Compliance: While both KeyDB and Tarantool support transactions, Tarantool provides ACID compliance by enforcing strong consistency and durability guarantees. KeyDB, being a Redis-compatible database, adheres to Redis' eventual consistency model and does not offer the same level of durability guarantees.

  6. Community and Ecosystem: Tarantool has a vibrant and active community with a wide range of plugins, modules, and tools available for developers. In comparison, KeyDB, being a relatively newer project, has a smaller but growing community and a more limited ecosystem.

In summary, KeyDB and Tarantool differ in their architecture, data modeling capabilities, replication techniques, language support, transactional features, and community size. Developers should carefully consider their specific requirements and use cases to determine which database management system best aligns with their needs.

What are some alternatives to Tarantool, KeyDB?

Redis

Redis

Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.

Hazelcast

Hazelcast

With its various distributed data structures, distributed caching capabilities, elastic nature, memcache support, integration with Spring and Hibernate and more importantly with so many happy users, Hazelcast is feature-rich, enterprise-ready and developer-friendly in-memory data grid solution.

Aerospike

Aerospike

Aerospike is an open-source, modern database built from the ground up to push the limits of flash storage, processors and networks. It was designed to operate with predictable low latency at high throughput with uncompromising reliability – both high availability and ACID guarantees.

MemSQL

MemSQL

MemSQL converges transactions and analytics for sub-second data processing and reporting. Real-time businesses can build robust applications on a simple and scalable infrastructure that complements and extends existing data pipelines.

Apache Ignite

Apache Ignite

It is a memory-centric distributed database, caching, and processing platform for transactional, analytical, and streaming workloads delivering in-memory speeds at petabyte scale

SAP HANA

SAP HANA

It is an application that uses in-memory database technology that allows the processing of massive amounts of real-time data in a short time. The in-memory computing engine allows it to process data stored in RAM as opposed to reading it from a disk.

VoltDB

VoltDB

VoltDB is a fundamental redesign of the RDBMS that provides unparalleled performance and scalability on bare-metal, virtualized and cloud infrastructures. VoltDB is a modern in-memory architecture that supports both SQL + Java with data durability and fault tolerance.

Azure Redis Cache

Azure Redis Cache

It perfectly complements Azure database services such as Cosmos DB. It provides a cost-effective solution to scale read and write throughput of your data tier. Store and share database query results, session states, static contents, and more using a common cache-aside pattern.

LokiJS

LokiJS

LokiJS is a document oriented database written in javascript, published under MIT License. Its purpose is to store javascript objects as documents in a nosql fashion and retrieve them with a similar mechanism. Runs in node (including cordova/phonegap and node-webkit), nativescript and the browser.

BuntDB

BuntDB

BuntDB is a low-level, in-memory, key/value store in pure Go. It persists to disk, is ACID compliant, and uses locking for multiple readers and a single writer. It supports custom indexes and geospatial data. It's ideal for projects that need a dependable database and favor speed over data size.
