Memory mapped files

Ebook "Core Java: Volume II – Advanced features (10th edition)" fully updated for Java SE 8. The first volume covers the essential features of the language; this volume deals with the advanced topics that a programmer needs to know for professional software development. Thus, as with the first volume and the previous editions of this book, we are still targeting programmers who want to put Java technology to work in real projects.

Chapter 6 - Virtual memory. This chapter deals with virtual memory implementation using paging in detail. It discusses how the kernel keeps the code and data of a process on a disk and loads parts of it into memory when required, and how the performance of a process is determined by the rate at which parts of a process have to be loaded from the disk.

Looping is avoided in retrieving a particular data from huge datasets and it consumes less amount of time for executing the data. HDFS file system is used to store the data after performing the map reduce operations and the execution time is decreased when the number of nodes gets increased. The performance analysis is tuned with the parameters such as the HBase Heap Memory and Caching Parameter.

Memory-mapped file functionality –Map virtual memory space directlyto normal files. Advantages –No need to perform direct file I/O –Data structures created in memory will be saved in the file for later use –In-memory algorithms can process file data even though the file is much larger than available physical memory –Improvement of file processing performance –No need to manage buffers and the file data –Multiple processes can share memory
