What is ElasticImageCache?
ElasticImageCache is an open-source, distributed image caching system designed to scale horizontally across multiple nodes. It provides a fast, low-latency way to store and retrieve images for websites and applications.
Some key features of ElasticImageCache include:
- Distributed architecture - The cache is spread across multiple nodes in a cluster, allowing it to scale easily as traffic increases.
- Automatic load balancing - Requests are automatically distributed across cache nodes.
- Disk and memory caching - Recently accessed images are stored in memory for extra speed, while less popular images go to disk.
- Cache invalidation - Images can be purged from the cache when they are updated.
- CDN and cloud integration - Works great with content delivery networks and cloud platforms like AWS, Azure and Google Cloud.
ElasticImageCache is implemented in Java and provides client libraries for Java, .NET and other languages. It uses consistent hashing for partitioning and data replication across nodes. Overall, it's an efficient, scalable solution for caching images to improve website performance.
