is a row-oriented database. 3. Hive itself does not store and compute data. It relies entirely on the pure table logic in HDFS, mapreduce, and hive. 4. hbase is generated for query. It organizes the memory of all machines in the node and provides a large memory hash table. 5. hbase is not a relational database, but a column-Oriented Distributed Database develope

Label:Many developers in the database design often do not have much to consider char, varchar type, some are not pay attention to, because the storage price has become more and more cheap, forget the beginning of some basic design theory and principles, this reminds me of the present young people, Big hand a wave of renminbi from his hands slipped away, in fact, I think whether it is a person or do developm

high-speed cache memory between the CPU register and the primary memory called the L1 cache, it can be accessed within 2-4 clock periods. Later, it was found that there was a large gap between the L1 high-speed cache and the primary storage, and a faster L2 cache was inserted between the L1 high-speed cache and the primary storage, it can be accessed within 10 clock cycles. Therefore, in this mode, the cur

. Also, a network application can bind to the port it needs (such as the 53 port of BIND), but it cannot bind to other ports.The domain-type model means that each process running in the security domain and each resource (generic, directory, socket, and so on) has a "type" associated with it.On top of that, a series of rules are set up that lists all the actions that a domain can perform on each type. One advantage of the domain-type model is that we c
