MySQL is a better NoSQL. When considering a NoSQL use case, such as key/value storage, MySQL makes more sense in terms of performance, ease of use, and stability. MySQL is a solid engine with lots of online material, ranging from operations and failure cases, to replication and different patterns of usage. For this reason, it has an advantage over newer NoSQL engines that are not as battle tested.
NoSQL before nosqlCAP not really too relevant. If you’re using a NoSQL database, you probably are running on a cluster with multiple partitions. And consistency – availability is not necessarily easy to interpret except in a formal theoretical way.Plus, it’s tunable. Plus, what does consistency even mean? Example, Cassandra partial writes. What is a secondary index more key-value lookupsit’s jus
G-WAN better uses CPU Cores to make the Internet of Things fly thousand times higher ! Leverage legacy servers and low-consumption CPUs to do more with less! With 1GHz in 2000 and 3GHz in 2002 10GHz CPUs were expected in 2005. Today, we should run much faster CPUs but: We're not going to have faster processors. Instead, making software run faster in the future will mean using parallel-programming
