Learn about Tango caching technology

With the continuous development of Internet technology, a large amount of data is stored in servers, and requires fast and efficient response to read and write operations. In order to improve server performance and user experience, caching technology has become one of the solutions commonly used by Internet companies. Tango caching technology is one of many caching technologies.

Tango caching technology is a memory-based caching system developed by Google. It adopts a multi-level cache structure and adaptive optimization algorithm, which can effectively improve data access speed and access hit rate, thus improving the overall performance of the system.

In Tango cache, data is divided into multiple levels for caching, and each level has different storage size and read and write speed. The first is the L1 cache, which is located inside the CPU and exists in the form of a cache. The size is generally tens of KB and the speed is very fast. The L1 cache is primarily used to cache frequently accessed data, such as CPU registers or frequently used code. The second is the L2 cache, which is located on the CPU chip, is generally a few hundred KB or larger in size, and is slower than the L1 cache. The L2 cache is mainly used to cache data and code, and the L1 cache does not cache data. Finally, there is the L3 cache, which is located on the chip outside of the CPU, is typically several MB or larger in size, and is much slower than the L2 cache. L3 cache is mainly used to cache data that has not been used for a long time or is rarely accessed.

Tango caching technology also uses some adaptive optimization algorithms, such as automatically adjusting cache size to adapt to changes in access load, or automatically adjusting cache levels and caching strategies based on data popularity. These algorithms can make the Tango cache system more intelligent and adaptive, improving the data access hit rate and the performance of the entire system.

In addition, Tango caching technology also has a variety of features, such as multi-threading support, fault recovery, monitoring and debugging tools, etc. Multi-thread support can improve the efficiency of concurrent data access, fault recovery can ensure the security and integrity of cached data, and monitoring and debugging tools can easily monitor and maintain the cache running status.

Taken together, Tango cache technology is a highly optimized and intelligent cache system. Its multi-level cache structure and adaptive optimization algorithm can help Internet companies improve data access speed and access hit rate, and improve the system overall performance. If you are developing or maintaining Internet applications, then considering using Tango caching technology would be a good choice.
