IBM uses Stinger to name the new version of DB2 Universal Database, which shows that this product will have fast, powerful, and efficient features, using the "Stinger" independent database, it can automatically handle maintenance tasks such as fault handling and system monitoring that were previously undertaken by the database administrator, reducing the labor intensity by 80%, greatly improving the work ef
[CCID news] on the evening of April September 8, IBM launched a new version of database software for Linux and UNIX operating system users, hoping to seize some market share from the market-leading oracle.
IBM said that the latest version of DB2 software can run on Linux and UNIX and allow the database to automatically "manage itself ", this allows some companies to manage, process, and restore product prices more efficiently.
According to IBM, the latest database software named

But Microsoft has gradually adjusted its PC mindset to develop hardware that is designed for low memory and low computational speed. With a lot of money invested in small-screen devices, Microsoft is regaining market share that has been encroached on by other vendors and moving towards the eventual interaction of large-screen devices and small-screen devices.

Streaming must guarantee strict data transfer and intermediate state persistence.These features are not critical for batch processing where the calculation process is very convenient to restart.
Flow processing is inseparable from piping. For batch processing, the pipeline is less critical and not applicable in some scenarios. Apache Hive is based on a phased process of mapreduce, in which intermediate results are materialize

MapReduce-based Hadoop is suitable for batch processing of data, but is not suitable for ad hoc query scenarios. MySQL, which is based on the Innodb/myisam storage engine, is naturally unsuitable. Of course we've also looked at Infinidb/infobright, the Columnstore database engine (still based on MySQL), which is more suitable for historical archival
