Introduction ofCouchbase
At present, the most used Cache system in C # industry is mainly memcached and Redis. These two Cache system can be said to be a more mature solution, but also many systems of course choice. Memcache is basically the standard of development, but for the memcache cluster, many online deployments are still very thin. Several existing problems: not robust, data insecurity, configuration chang

Currently, the most widely used Cache systems in the C # industry are Memcached and Redis. These two Cache systems can be said to be relatively mature solutions, but also the choice of many systems.

In the previous article we introduced the differences between Redis and Couchbase and show their respective strengths (please poke the blue bold font: Couchbase vs Redis, which one is better. )。 This article will provide developers with the most real and powerful data support, so that technology selection more objective, so that the cluster expansion is no longer blind, in the predictable business scale, so
This article does not intend to copy the official or to cite other people's descriptions of couchbase, just a little understanding of it (the error, please note), and attach an introductory example.An ASP. NET Web project (same as other web development platforms) when the application is small, it can be cached using the caching mechanism that comes with it, however, when the project application scale is big, then the perpetual application goes on, I a

Looking back at my previous blog, in Fabric 1.0, we have 3 types of data storage, one is based on the filesystem block chain data, which is very much like the bitcoin, bitcoin is stored in the form of files. The block chain in Fabric1.0 stores the transaction order read and write sets. and read-write collection is exactly what it reads. Write what. In fact, our state Database, also known as the world, stores the business data we operate in Chaincode in a key-value pair. There is also the databas
