kandi X-RAY | hyrise-v1 Summary

hyrise-v1 is a C++ library. hyrise-v1 has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Traditional databases are separated into ones for current data from the day-to- day business processes and ones for reporting and analytics. For fast moving businesses moving data from one silo to another is cumbersome and takes too much time. As a result the new data arriving in the reporting system is already old by the time it is loaded. HYRISE proposes a new way to solve this problem: It analyzes the query input and reorganizes the stored data in different dimensions. In detail, HYRISE partitions the layout of the underlying tables in a vertical and horizontal manner depending on the input to this layout management component. The workload is specified as a set of queries and weights and is processed by calculating the layout dependent costs for those queries. Based on our cost-model we can now calculate the best set of partitions for this input workload. This optimization allows great speed improvements compared to traditional storage models. This database provides the implementation to the above mentioned ideas.

Install hyrise-v1

Supported (actively tested through CI and in development) systems:. HYRISE expects a C++11-capable compiler. We recommend g++ >=4.7, testing is done against g++ 4.7, g++ 4.8 and clang 3.2.
Ubuntu (>13.04)
MacOSX 10.7
You can use the official HYRISE development image to start a docker container with all dependencies for building HYRISE already installed. See Docker README for more information on how to use it. Using VirtualBox and Vagrant, you can automatically setup a HYRISE development environment. (This is the recommended way of getting started with HYRISE development). Check out this repository to easily setup a development VM. It should be sufficient to run the install_$version.sh script from the tools/ folder, where version corresponds to a Ubuntu version.
The build can be configured through a build settings file settings.mk. Copy the file makefiles/settings.mk.default to settings.mk and if necessary modify settings. The most prominent option is setting BLD to release, which disables the debug build, and HYRISE_ALLOCATOR for using tcmalloc or jemalloc instead of the libc allocator.

Support

The project provides some documentation about how to develop and use HYRISE. The documentation can be build using:. The documentation contains information about how to use HYRISE and how to implement own plan operations and table types etc.
