winzip compression

Preface: Table Compression should be supported from 10 Gb. Oracle 11g exadata used this feature to the extreme and vigorously promoted the compression technology. In the condition that the cpu performance of modern machines is blowout, the reduction of IO and memory usage is particularly important. compression technology will certainly be a common technology in t

There are two types of data compression:Lossless CompressionAndLossy Compression. Lossless Compression The so-called lossless compression format uses statistical redundancy to compress the data. It can completely restore the original data without causing any distortion. However, the compression rate is limited by the t

IIS compression is not a new technology, but for Sharepoint sites, IIS compression can play a major role. After the IIS compression function is enabled on the IIS server, before the IIS server sends the page content to the browser, It compresses the content on the server and then sends the compressed data, after the browser receives the data, it automatically dec

Label: style HTTP color Io OS ar Java1 compression Generally, data processed by computers has some redundancy and there is correlation between data, especially between adjacent data. Therefore, data can be stored in special encoding methods different from the original encoding, make the storage space occupied by data relatively small, this process is generally called compression. The concept corresponding t

In Linux, there are many compression commands. Using these compression commands, you can easily download large files from the network. At the same time, we know that the Linux File Extension has no special significance. However, because there are many compression commands in Linux, in order to facilitate memory, some special naming methods will be performed on th

It is amazing that the string table can be correctly created during compression or decompression. After compression or decompression, the string table is discarded. Tags:LZW

Hadoop's support for compressed files Hadoop supports transparent identification of compression formats, and execution of our mapreduce tasks is transparent. hadoop can automatically decompress the compressed files for us without worrying about them. If the compressed file has an extension (such as lzo, GZ, and Bzip2) of the corresponding compression format, hadoop selects the decoder to decompress the

First, Gzip introductionGZIP is the abbreviation for GNU Zip, which is a file compression program for GNU Free Software and is often used to represent the gzip file format. The authors of the software are Jean-loup gailly and Mark Adler. October 31, 1992 the first public release, the version number is 0.1, the current stable version is 1.2.4.Gzip is primarily used for file compression on UNIX systems. We of

1. decide which objects to compress Sp_estimate_data_compression_savings evaluates the amount of space that is saved separately from row and page compression. When the table contains the following data patterns, it has a good compression effect: Columns of numeric types and fixed-length character type data, but most of the values of both do not use all the bytes of this type. Values such as int co

When you hear this word about Oracle Database compression, you must think of saving hard disk space. Yes, it is used to do this, but extending it out not only saves hard disk space, it can also save bandwidth and memory usage (cpu consumption is slightly reduced because more computing value operations are required, but in most environments the cpu is idle, so you can ignore it ).Basic compression is provide
