Learn about Hazelcast Jet caching technology

Hazelcast Jet is a fast, high-performance real-time data processing and analysis engine. As a distributed computing engine, Hazelcast Jet provides a series of data processing and caching services, of which Hazelcast Jet caching technology is an important part.

Hazelcast Jet caching technology is implemented based on Hazelcast distributed memory cache, providing distributed memory cache structure, namespace, data expiration and expiration strategies, cache listeners and other services. When using Hazelcast Jet caching technology, we can customize object serialization and deserialization methods, cache loading and persistence methods, cache deployment and expansion methods, etc.

Among them, the distributed memory cache structure of Hazelcast Jet caching technology is the key to realizing distributed data storage and access. Hazelcast Jet caching technology distributes data to multiple nodes while providing services such as failover and load balancing. Through distributed caching, we can achieve high-performance, highly reliable data access and storage.

As a core component of Hazelcast Jet caching technology, namespaces provide a mechanism to distinguish different cached data collections. Through namespace, we can divide the cached data collection into multiple independent logical groups to avoid naming conflicts and confusion between different cached data. At the same time, the namespace can also be flexibly and dynamically added and deleted, which improves the convenience of cache data management.

Cache invalidation is one of the important contents of cache management. Hazelcast Jet caching technology provides flexible data expiration and expiration policy mechanisms. By setting the expiration time and expiration policy, we can automatically clean up cached data that is no longer used to avoid the cache occupying too much memory and reducing performance. In terms of expiration policies, Hazelcast Jet caching technology supports multiple expiration policies such as least recently used (LRU) and least frequently used (LFU), providing users with a variety of choices.

In addition to the expiration mechanism, Hazelcast Jet caching technology also supports cache listeners, providing a real-time notification mechanism for cached data changes. By monitoring the addition, deletion and modification operations of cached data, we can achieve timely response and processing of cached data changes. For cached data that needs to be updated in a timely manner, the listener mechanism is very helpful.

In addition to basic caching services, Hazelcast Jet caching technology also supports a variety of extended functions. Among them, custom object serialization and deserialization is a common extension method. By implementing object serialization and deserialization interfaces, we can customize the serialization and deserialization methods of Hazelcast Jet objects to improve the efficiency of data transmission and storage. In addition, we can also customize cache loading and persistence methods, and further optimize system performance and reliability by integrating different storage technologies and cache deployment methods.

To sum up, Hazelcast Jet caching technology is a powerful part of Hazelcast Jet. It provides distributed memory cache structure, namespace, expiration policy, cache listener and many extended functions to achieve high performance for us. , highly reliable real-time data processing and analysis provide strong support.
