KeyDB vs VoltDB: What are the differences?

### Introduction
KeyDB and VoltDB are two different database management systems that offer unique features and functionalities. Understanding the key differences between these two platforms can help in making an informed decision based on specific needs and requirements.

1. **Architecture**: KeyDB is an in-memory database that supports persistent storage, whereas VoltDB is an in-memory database that is designed for high-velocity, real-time applications.
2. **Consistency Model**: KeyDB follows an eventually consistent model, ensuring that updates are eventually propagated to all nodes, while VoltDB offers strong consistency ensuring that all reads reflect the latest write.
3. **Programming languages and APIs**: KeyDB supports multiple programming languages and offers compatibility with the Redis API, making it easier for users to transition from Redis. VoltDB, on the other hand, provides support for Java stored procedures and SQL for application development.
4. **Scaling**: KeyDB offers sharding and partitioning capabilities for horizontal scaling, while VoltDB provides automatic partitioning for data distribution across nodes in a cluster.
5. **Use Cases**: KeyDB is commonly used for real-time analytics, caching, and messaging, while VoltDB is ideal for applications requiring high throughput and low latency such as gaming, fraud detection, and telecommunications.
6. **Consistency vs Performance**: While KeyDB prioritizes performance and lower latencies, VoltDB emphasizes strong consistency and ACID compliance, making it suitable for applications requiring transactional integrity.

In Summary, understanding the differences in architecture, consistency model, programming languages, scaling options, use cases, and trade-offs between consistency and performance can help in choosing between KeyDB and VoltDB for specific database requirements.

What are some alternatives to VoltDB, 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.

Tarantool

Tarantool

It is designed to give you the flexibility, scalability, and performance that you want, as well as the reliability and manageability that you need in mission-critical applications

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.
