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.

When it comes to digital steganography no stone should be left unturned in the search for viable hidden data. Although digital steganography is commonly used to hide data inside multimedia files, a similar approach can be used to hide data in archives as well. Steganography imposes the following data hiding rule: Data must be hidden in such a fashion that the user has no clue about the hidden message or file's existence. This can be achieved by

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.

  • Rule Base with Frequent Bit Pattern and Enhanced K-Medoid Algorithm for the Evaluation of Lossless Data Compression
    Volume 3, No. 1, Jan-Feb 2012 ISSN No. 0976-5697 International Journal of Advanced Research in Computer Science RESEARCH PAPER Available Online at www.ijarcs.info Rule Base with Frequent Bit Pattern and Enhanced k-Medoid Algorithm for the Evaluation of Lossless Data Compression. Nishad P.M.* Dr. N. Nalayini Ph.D Scholar, Department Of Computer Science Associate professor, Department of computer science NGM NGM College, Pollachi, India College Pollachi, Coimbatore, India [email protected] [email protected] Abstract: This paper presents a study of various lossless compression algorithms; to test the performance and the ability of compression of each algorithm based on ten different parameters. For evaluation the compression ratios of each algorithm on different parameters are processed. To classify the algorithms based on the compression ratio, rule base is constructed to mine with frequent bit pattern to analyze the variations in various compression algorithms. Also, enhanced K- Medoid clustering is used to cluster the various data compression algorithms based on various parameters. The cluster falls dissentingly high to low after the enhancement. The framed rule base consists of 1,048,576 rules, which is used to evaluate the compression algorithm. Two hundred and eleven Compression algorithms are used for this study. The experimental result shows only few algorithm satisfies the range “High” for more number of parameters. Keywords: Lossless compression, parameters, compression ratio, rule mining, frequent bit pattern, K–Medoid, clustering. I. INTRODUCTION the maximum shows the peek compression ratio of algorithms on various parameters, for example 19.43 is the Data compression is a method of encoding rules that minimum compression ratio and the 76.84 is the maximum allows substantial reduction in the total number of bits to compression ratio for the parameter EXE shown in table-1 store or transmit a file.

  • Preparing and Submitting Electronic Files for the IEEE 2000 Mobile Ad Hoc Networking and Computing Conference (Mobihoc)
    Preparing and Submitting Electronic Files for the IEEE 2000 Mobile Ad Hoc Networking and Computing Conference (MobiHOC) Please read the detailed instructions that follow before you start, taking particular note of preferred fonts, formats, and delivery options. The quality of the finished product is largely dependent upon receiving your help at this stage of the publication process. Producing Your Paper Acceptable Formats Papers can be submitted in either PostScript (PS) or Portable Document Format (PDF) (see Generating PostScript and PDF Files). Using LaTeX Documents converted from the TeX typesetting language into PostScript or PDF files usually contain fixed-resolution bitmap fonts that do not print or display well on a variety of printer and computer screens. Although Adobe Acrobat Distiller will convert a PostScript language file with bitmapped fonts (level 3) into PDF, these fonts display slowly and do not render well on screen in the resulting PDF file. But, if you use Type 1 versions of the fonts you will get a compact file format that delivers the optimal font quality when used with any display screen, zoom mode, or printer resolution. Using Type 1 fonts with DVIPS The default behavior of Rokicki's DVIPS is to embed Type 3 bitmapped fonts. You need access to the Type 1 versions of the fonts you use in your documents in order to embed the font information (see Fonts). Type 1 versions of the Computer Modern fonts are available in the BaKoMa collection and from commercial type vendors. Before distributing files with embedded fonts, consult the license agreement for your font package.

  • Administer Security Policy with Securezip
    Administer Security Policy with SecureZIP for Windows Enterprise Edition SecureZIP Enterprise Edition enables you to implement, deploy, and enforce security policies affecting any data your end users work with in SecureZIP. PKWARE Policy Manager is a Microsoft Management Console (MMC) snap- in. It provides a command center from which you can bring to bear SecureZIP’s arsenal of security features to improve efficient transfer of data and help maintain regulatory compliance whenever SecureZIP is used by anyone in your organization. Note: This document mostly refers to SecureZIP. Users of PKZIP Enterprise Edition can only set policies and define standards for passphrase-based strong encryption. Glossary Some terms associated with PKWARE Policy Manager can be confusing. Table 1 clarifies the most important. Table 1: PKWARE Policy Manager Glossary Term Definition Contingency Key Contingency keys enable an organization to decrypt files encrypted by anyone in the organization, whether the files are passphrase encrypted or encrypted for specific recipients. Contingency keys are a safeguard to be sure that important information belonging to the organization does not become inaccessible because no one in the organization can decrypt it. Policy A particular set of SecureZIP configuration options that specifies contingency keys and determines how SecureZIP compresses, encrypts, or digitally signs files or email attachments. Policy Certificate Digital certificate selected by an administrator for PKWARE Policy Manager to sign policy files. SecureZIP authenticates a policy file by checking that it is signed by a policy certificate. Policy File When a policy is defined and a policy certificate is associated to that policy, Policy Manager saves that information to a policy file with a .szp extension.
