Some people who know siwft know that ring is a very core component of swift and determines how data is distributed in the cluster. Swift determines the number of partitions in the Cluster Based on the configured partition_power (2 to the power of
Outputting "helloworld" from the console is the first step in C language learning and a very important step in my life. Today, many years later, I still hope to use helloworld as the first step to start a magical and magnificent world-Swift
After the swift language comes out, new projects may be developed directly using SWIFT, but some situations may occur in the process, some classes or encapsulated modules that have been written with OC, if you don't want to write it again in swift,
