Infinispan vs. Dragonfly

Dragonfly is a robust caching solution and a seamless alternative to Redis, Valkey, and Memcached. It utilizes the same protocols, ensuring that current cache clients and application code remain functional without modification. With its multi-threaded design, Dragonfly efficiently distributes read and write operations across all CPU cores, achieving an impressive throughput of up to 6 million operations per second on a single node while maintaining consistently low latency during peak usage. Organizations can streamline their caching strategy by reducing large, sharded cache clusters to a smaller number of instances; for example, Instacart was able to decrease its cluster size by 70% while halving average latency. Its memory-optimized architecture allows for increased data storage per gigabyte, and the integrated cache mode with adaptive eviction maximizes hit rates without the need for manual adjustments. Dragonfly is ideal for various use cases, including application caching, session management, rate limiting, leaderboards, and API response caching, and can be deployed either as a self-hosted solution or through Dragonfly Cloud.

Dragonfly Cloud is an advanced, fully managed in-memory data storage solution based on Dragonfly, a database that is compatible with both Redis and Valkey, optimized for contemporary hardware. This service takes care of all aspects such as provisioning, scaling, ensuring high availability, performing backups, and managing upgrades. This allows engineering teams to concentrate on developing their applications rather than managing clusters. Leveraging a multi-threaded architecture, Dragonfly maximizes the performance of each instance, resulting in superior throughput per dollar compared to other managed services that rely on single-threaded systems. For instance, Instacart achieved a 70% reduction in cluster size along with a 50% decrease in average latency, while redBus was able to double their throughput and simultaneously halve latency. Users can seamlessly transition from platforms like ElastiCache or Memorystore, as existing Redis and Valkey clients and commands remain unchanged. Dragonfly Cloud is versatile, catering to various needs such as caching, session management, queuing, real-time data analytics, and AI applications including feature stores and vector searches.

Dragonfly is an innovative in-memory database specifically designed for the capabilities of modern multi-core cloud systems. Unlike conventional in-memory databases such as Redis, which operate on a single thread and necessitate costly clustering as demand increases, Dragonfly employs a multi-threaded, shared-nothing design that utilizes all available cores. This architecture can achieve throughput levels up to 25 times greater than Redis on identical hardware, with the ability to handle as many as 6 million operations per second per node. It seamlessly supports both the Redis and Valkey APIs, enabling teams to transition effortlessly without the need to alter their existing codebase. Additionally, the Dashtable data structure minimizes memory usage by as much as 40%, while fork-free snapshotting mitigates the risk of memory surges that can disrupt larger instances. Notable companies such as Instacart, redBus, and Meesho leverage Dragonfly to enhance performance and cut infrastructure expenses. It is offered in both self-managed and fully managed formats via Dragonfly Cloud.

Dragonfly is an advanced in-memory data storage solution designed to maximize the capabilities of contemporary cloud systems. Its architecture is multi-threaded and shared-nothing, efficiently utilizing every core on a single instance to achieve performance levels of up to 6 million operations per second per node. This allows teams to operate with fewer, smaller machines instead of extensive clusters. Dragonfly supports both the Redis and Valkey APIs, enabling a seamless migration for existing applications without requiring any code modifications. For infrastructure and platform teams, this translates to reduced costs in computing and memory usage; for instance, Instacart managed to decrease its cluster size by 70%, while Meesho experienced a 60% reduction in expenses. Dragonfly prioritizes vertical scaling initially, resorting to horizontal scaling only when necessary, which simplifies the overall architecture and streamlines operations. It can be deployed in a self-managed manner on any cloud virtual machine or Kubernetes, or users can opt for Dragonfly Cloud to handle provisioning, scaling, and maintenance tasks.

Dragonfly is an advanced key-value database designed for high throughput and is fully compatible with the Redis and Valkey APIs. It offers support for various data types including strings, hashes, lists, sets, sorted sets, streams, JSON, and more, enabling applications that utilize Redis clients to operate seamlessly on Dragonfly without any modifications. Featuring a multi-threaded, shared-nothing architecture, Dragonfly can handle requests concurrently across all CPU cores, achieving performance levels of up to 6 million operations per second per node while maintaining consistently low latency even under heavy load. The innovative Dashtable data structure minimizes memory usage by as much as 40%, allowing teams to manage a greater number of keys with less hardware investment. Dragonfly’s snapshotting mechanism avoids the memory spikes typically associated with fork-based persistence, ensuring that large datasets remain stable during backup processes. It efficiently manages extremely large datasets on a single node, delaying the need for clustering and simplifying operational tasks. Users can choose to deploy Dragonfly either in a self-hosted environment or as a fully managed solution on Dragonfly Cloud.
