BOX 11000, 00076 AALTO www.aalto.fi Abstract of the master’s thesis Author Michael Burman Title Implementing compression on distributed time series database Degree programme Major Computer Science Code of major SCI3042 Supervisor Prof. Kari Smolander Advisor Mgr. Jiri Kremser Date 05.11.2017 Number of pages 70+4 Language English Abstract Rise of microservices and distributed applications in containerized deployments are putting increasing amount of burden to the monitoring systems. They push the storage requirements to provide suitable performance for large queries. In this paper we present the changes we made to our distributed time series database, Hawkular-Metrics, and how it stores data more effectively in the Cassandra. We show that using our methods provides significant space savings ranging from 50 to 95% reduction in storage usage, while reducing the query times by over 90% compared to the nominal approach when using Cassandra. We also provide our unique algorithm modified from Gorilla compression algorithm that we use in our solution, which provides almost three times the throughput in compression with equal compression ratio.

The Ark Handbook Chapter 1 Introduction Ark is a program for viewing, extracting, creating and modifying archives. Ark can handle vari- ous archive formats such as tar, gzip, bzip2, zip, rar, 7zip, xz, rpm, cab, deb, xar and AppImage (support for certain archive formats depends on the appropriate command-line programs being installed). In order to successfully use Ark, you need KDE Frameworks 5. The library libarchive version 3.1 or above is needed to handle most archive types, including tar, compressed tar, rpm, deb and cab archives. To handle other file formats, you need the appropriate command line programs, such as zipinfo, zip, unzip, rar, unrar, 7z, lsar, unar and lrzip. 5 The Ark Handbook Chapter 2 Using Ark 2.1 Opening Archives To open an archive in Ark, choose Open... (Ctrl+O) from the Archive menu. You can also open archive files by dragging and dropping from Dolphin.

    zlib Home Site http://zlib.net/ A Massively Spiffy Yet Delicately Unobtrusive Compression Library (Also Free, Not to Mention Unencumbered by Patents) (Not Related to the Linux zlibc Compressing File-I/O Library) Welcome to the zlib home page, web pages originally created by Greg Roelofs and maintained by Mark Adler . If this page seems suspiciously similar to the PNG Home Page , rest assured that the similarity is completely coincidental. No, really. zlib was written by Jean-loup Gailly (compression) and Mark Adler (decompression). Current release: zlib 1.2.6 January 29, 2012 Version 1.2.6 has many changes over 1.2.5, including these improvements: gzread() can now read a file that is being written concurrently gzgetc() is now a macro for increased speed Added a 'T' option to gzopen() for transparent writing (no compression) Added deflatePending() to return the amount of pending output Allow deflateSetDictionary() and inflateSetDictionary() at any time in raw mode deflatePrime() can now insert bits in the middle of the stream ./configure now creates a configure.log file with all of the results Added a ./configure --solo option to compile zlib with no dependency on any libraries Fixed a problem with large file support macros Fixed a bug in contrib/puff Many portability improvements You can also look at the complete Change Log . Version 1.2.5 fixes bugs in gzseek() and gzeof() that were present in version 1.2.4 (March 2010). All users are encouraged to upgrade immediately. Version 1.2.4 has many changes over 1.2.3, including these improvements:

  • Working with Compressed Archives
    Working with compressed archives Archiving a collection of files or folders means creating a single file that groups together those files and directories. Archiving does not manipulate the size of files. They are added to the archive as they are. Compressing a file means shrinking the size of the file. There are software for archiving only, other for compressing only and (as you would expect) other that have the ability to archive and compress. This document will show you how to use a windows application called 7-zip (seven zip) to work with compressed archives. 7-zip integrates in the context menu that pops-up up whenever you right-click your mouse on a selection1. In this how-to we will look in the application interface and how we manipulate archives, their compression and contents. 1. Click the 'start' button and type '7-zip' 2. When the search brings up '7-zip File Manager' (as the best match) press 'Enter' 3. The application will startup and you will be presented with the 7-zip manager interface 4. The program integrates both archiving, de/compression and file-management operations. a. The main area of the window provides a list of the files of the active directory. When not viewing the contents of an archive, the application acts like a file browser window. You can open folders to see their contents by just double-clicking on them b. Above the main area you have an address-like bar showing the name of the active directory (currently c:\ADG.Becom). You can use the 'back' icon on the far left to navigate back from where you are and go one directory up.

  • Deduplicating Compressed Contents in Cloud Storage Environment
    Deduplicating Compressed Contents in Cloud Storage Environment Zhichao Yan, Hong Jiang Yujuan Tan* Hao Luo University of Texas Arlington Chongqing University University of Nebraska Lincoln [email protected] [email protected] [email protected] [email protected] Corresponding Author Abstract Data compression and deduplication are two common approaches to increasing storage efficiency in the cloud environment. Both users and cloud service providers have economic incentives to compress their data before storing it in the cloud. However, our analysis indicates that compressed packages of different data and differ- ently compressed packages of the same data are usual- ly fundamentally different from one another even when they share a large amount of redundant data. Existing data deduplication systems cannot detect redundant data among them. We propose the X-Ray Dedup approach to extract from these packages the unique metadata, such as the “checksum” and “file length” information, and use it as the compressed file’s content signature to help detect and remove file level data redundancy. X-Ray Dedup is shown by our evaluations to be capable of breaking in the boundaries of compressed packages and significantly Figure 1: A user scenario on cloud storage environment reducing compressed packages’ size requirements, thus further optimizing storage space in the cloud. will generate different compressed data of the same con- tents that render fingerprint-based redundancy identifi- cation difficult.
