OverviewIn the field of distributed real-time computing, how to make the framework/engine to be efficient enough to access and process large amounts of data in memory is a very difficult problem. Flink is undoubtedly doing very well in dealing with this problem, Flink's autonomic memory management design may be higher than its own popularity. Just recently in the study of Flink source, so open two articles

operations are often one of the root causes of errors. For example, "Memory leakage"-failure to correctly release allocated dynamic memory is a memory error that is very difficult to detect. The continuous memory leakage will make the program performance fall to the end of completely unable to run, and thus affect all other programs with dynamic memory requirements, some relatively simple embedded platforms may even impede the operation of the operating system. Another example is "writing memor

Realization principle of 20.1.5.2 Tmemorystream object Tmemorystream inherits directly from the Tcustommemorystream object, so you can enjoy the properties and methods of Tcustommemorystream. As mentioned earlier, Tcustommemorystream is an abstract object for data manipulation in memory, which provides a framework for the implementation of MemoryStream objects and the contents of the framework to be populated by specific MemoryStream objects. The Tme

In the oracle8i version, Oracle has introduced a new way of tablespace management: a localized managed table space.Localized management means that Oracle no longer uses the data dictionary table to record the usage of the area inside the Oracle tablespace, but instead adds a bitmap area to the header of each table space's dat
