Stonebraker indicates that newsql provides some unique features of SQL and also has the scalability of nosql. Newsql has a new architecture design. It releases the buffer pool that consumes system resources in databases running the main memory. The voltdb system uses the innovative newsql architecture, which is 45 times faster than traditional relational databases in transaction execution. Voltdb has 39 scalable servers and can process 1.6 million transactions per second (300 CPU cores ).

Johnson left these people after he took office, but he couldn't understand what the pen wrote.Few listener types can make an effort to become a qualified reader-whether active or passive, and vice versa. Therefore, the person who tries to convert from listener to reader type will suffer the fate of Lyndon Johnson, and the person who tr
