Compare Dragonfly vs. KeyDB

Dragonfly serves as a seamless substitute for Redis, offering enhanced performance while reducing costs. It is specifically engineered to harness the capabilities of contemporary cloud infrastructure, catering to the data requirements of today’s applications, thereby liberating developers from the constraints posed by conventional in-memory data solutions. Legacy software cannot fully exploit the advantages of modern cloud technology. With its optimization for cloud environments, Dragonfly achieves an impressive 25 times more throughput and reduces snapshotting latency by 12 times compared to older in-memory data solutions like Redis, making it easier to provide the immediate responses that users demand. The traditional single-threaded architecture of Redis leads to high expenses when scaling workloads. In contrast, Dragonfly is significantly more efficient in both computation and memory usage, potentially reducing infrastructure expenses by up to 80%. Initially, Dragonfly scales vertically, only transitioning to clustering when absolutely necessary at a very high scale, which simplifies the operational framework and enhances system reliability. Consequently, developers can focus more on innovation rather than infrastructure management.

KeyDB ensures complete compatibility with Redis modules, APIs, and protocols, allowing for a seamless integration that retains the functionality of your existing clients, scripts, and configurations. You can effortlessly switch to KeyDB while maintaining this compatibility. Its Multi-Master mode provides a single replicated dataset across multiple nodes, facilitating both read and write operations. Additionally, nodes can be replicated across different regions to achieve submillisecond latencies for local clients. With Cluster mode, the dataset can be divided across shards, enabling limitless read and write scalability while simultaneously supporting high availability through replica nodes. KeyDB also introduces new community-driven commands that enhance your ability to manipulate data. You can create your own commands and features using JavaScript via the ModJS module, which allows for the writing of functions in JavaScript that can be directly invoked by KeyDB. An example of a JavaScript function that could be loaded with this module is provided on the left, demonstrating how it can be called directly from your client, showcasing the flexibility and power of KeyDB. This capability not only enhances your data handling but also fosters a more dynamic interaction with your database environment.
