For testing/development purposes, the system can be deployed using a smaller number of servers; however, it is not recommended to use such configurations for production. 1.1.2 Software requirements 1. As host operating systems, Tarantool Enterprise supports Red Hat Enterprise Linux and CentOS versions 7.5 and higher. Note: Tarantool Enterprise can run on other systemd-based Linux distributions but it is not tested on them and may not work as expected. 2. glibc 2.17-260.el7_6.6 and higher is required. Take care to check and update, if needed: $ rpm -q glibc glibc-2.17-196.el7_4.2 $ yum update glibc 1 Tarantool Enterprise manual, Release 1.10.4-1 1.1.3 Network requirements Hereinafter, “storage servers” or “Tarantool servers” are the computers used to store and process data, and “administration server” is the computer used by the system operator to install and configure the product. The Tarantool cluster has a full mesh topology, therefore all Tarantool servers should be able to commu- nicate and send traffic from and to TCP/UDP ports used by the cluster’s instances (see advertise_uri: <host>:<port> and config: advertise_uri: '<host>:<port>' in /etc/tarantool/conf.d/*.yml for each in- stance). For example: # /etc/tarantool/conf.d/*.yml myapp.s2-replica: advertise_uri: localhost:3305 # this is a TCP/UDP port http_port: 8085 all: ... hosts: storage-1: config: advertise_uri: 'vm1:3301' # this is a TCP/UDP port http_port: 8081 To configure remote monitoring or to connect via the administrative console, the administration server should be able to access the following TCP ports on Tarantool servers: • 22 to use the SSH protocol, • ports specified in instance configuration (http_port parameter) to monitor the HTTP-metrics. Additionally, it is recommended to apply the following settings for sysctl on all Tarantool servers: $ # TCP KeepAlive setting $ sysctl -w net.ipv4.tcp_keepalive_time=60 $ sysctl -w net.ipv4.tcp_keepalive_intvl=5 $ sysctl -w net.ipv4.tcp_keepalive_probes=5 This optional setup of the Linux network stack helps speed up the troubleshooting of network connectivity when the server physically fails. To achieve the maximum performance, you may also need

  • LIST of NOSQL DATABASES [Currently 150]
    Your Ultimate Guide to the Non - Relational Universe! [the best selected nosql link Archive in the web] ...never miss a conceptual article again... News Feed covering all changes here! NoSQL DEFINITION: Next Generation Databases mostly addressing some of the points: being non-relational, distributed, open-source and horizontally scalable. The original intention has been modern web-scale databases. The movement began early 2009 and is growing rapidly. Often more characteristics apply such as: schema-free, easy replication support, simple API, eventually consistent / BASE (not ACID), a huge amount of data and more. So the misleading term "nosql" (the community now translates it mostly with "not only sql") should be seen as an alias to something like the definition above. [based on 7 sources, 14 constructive feedback emails (thanks!) and 1 disliking comment . Agree / Disagree? Tell me so! By the way: this is a strong definition and it is out there here since 2009!] LIST OF NOSQL DATABASES [currently 150] Core NoSQL Systems: [Mostly originated out of a Web 2.0 need] Wide Column Store / Column Families Hadoop / HBase API: Java / any writer, Protocol: any write call, Query Method: MapReduce Java / any exec, Replication: HDFS Replication, Written in: Java, Concurrency: ?, Misc: Links: 3 Books [1, 2, 3] Cassandra massively scalable, partitioned row store, masterless architecture, linear scale performance, no single points of failure, read/write support across multiple data centers & cloud availability zones.

  • 3 Generic Programming with Mutually Recursive Types 27 3.1 the Generics-Mrsop Library
    2 Type-Safe Generic Differencing of Mutually Recursive Families Getypeerde Generieke Differentiatie van Wederzijds Recursieve Datatypes (met een samenvatting in het Nederlands) Proefschrift ter verkrijging van de graad van doctor aan de Universiteit Utrecht op gezag van de rector magnificus, prof. dr. H.R.B.M. Kummeling, ingevolge het besluit van het college voor promoties in het openbaar te verdedigen op maandag 5 oktober 2020 des ochtends te 11:00 uur door Victor Cacciari Miraldo geboren op 16 oktober 1991 te São Paulo, Brazilië Promotor: Prof.dr. G.K. Keller Copromotor: Dr. W.S. Swierstra Dit proefschrift werd (mede) mogelijk gemaakt met financiële steun van de Nederlandse Organisatie voor Wetenschappelijk Onderzoek (NWO), project Revision Control of Structured Data (612.001.401). To my Mother, Father and Brother Abstract The UNIX diff tool – which computes the differences between two files in terms ofa set of copied lines – is widely used in software version control. The fixed lines-of-code granularity, however, is sometimes too coarse and obscures simple changes, i.e., renam- ing a single parameter triggers the whole line to be seen as changed. This may lead to unnecessary conflicts when unrelated changes occur on the same line. Consequently, it is difficult to merge such changes automatically. In this thesis we discuss two novel approaches to structural differencing, generically – which work over a large class of datatypes. The first approach defines a type-indexed representation of patches and provides a clear merging algorithm, but it is computation- ally expensive to produce patches with this approach. The second approach addresses the efficiency problem by choosing an extensional representation for patches.

  • Tarantool Get Started Guide Draft 8
    L A U N C H Y O U R O W N R E S T F U L S E R V I C E I N 9 EASY STEPS Q U I C K S T A R T G U I D E 1 Tarantool has the great advantage of being an entirely self-sufficient backend solution, thus no external language like Node or PHP is necessary. This is because it includes a Lua application server that runs concurrent to its database server. In this tutorial, you will set up a basic Tarantool server on Ubuntu Linux using Digital Ocean. This responds to a route parameter with a user’s home city and returns that user’s name with a hello message. With some adjustments, this can also be accomplished on localhost using OSX, Linux, or Windows with WSL. S T A R T H E R E Sign up for Digital Ocean and create a basic Ubuntu droplet. Once you have its IP address, use SSH to access your instance. If you need help with setting up or 1. accessing your droplet, have a look at the beginning of the tutorial here. Once you have logged in, copy the script from https://tarantool.org/en/download/os-installation/1.7/ubuntu.html and paste it into 2. your terminal all at once. You may need to press enter again for the last line. After that we use apt-get to download an add-on Tarantool http module: 3. sudo apt-get install tarantool-http www.tarantool.io 1 Next we will set up an empty Tarantool database.

  • Storage Solutions for Big Data Systems: a Qualitative Study and Comparison
    Storage Solutions for Big Data Systems: A Qualitative Study and Comparison Samiya Khana,1, Xiufeng Liub, Syed Arshad Alia, Mansaf Alama,2 aJamia Millia Islamia, New Delhi, India bTechnical University of Denmark, Denmark Highlights Provides a classification of NoSQL solutions on the basis of their supported data model, which may be data- oriented, graph, key-value or wide-column. Performs feature analysis of 80 NoSQL solutions in view of technology selection criteria for big data systems along with a cumulative evaluation of appropriate and inappropriate use cases for each of the data model. Classifies big data file formats into five categories namely text-based, row-based, column-based, in-memory and data storage services. Compares available data file formats, analyzing benefits and shortcomings, and use cases for each data file format. Evaluates the challenges associated with shift of next-generation big data storage towards decentralized storage and blockchain technologies. Abstract Big data systems‘ development is full of challenges in view of the variety of application areas and domains that this technology promises to serve. Typically, fundamental design decisions involved in big data systems‘ design include choosing appropriate storage and computing infrastructures. In this age of heterogeneous systems that integrate different technologies for optimized solution to a specific real-world problem, big data system are not an exception to any such rule. As far as the storage aspect of any big data system is concerned, the primary facet in this regard is a storage infrastructure and NoSQL seems to be the right technology that fulfills its requirements. However, every big data application has variable data characteristics and thus, the corresponding data fits into a different data model.
