Currently we do not support scientific notation of decimal value.
Apache Doris (incubating)
Doris is an MPP-based interactive SQL data warehousing for reporting and analysis. It open-sourced by Baidu.
1. License
2. Technology
Doris mainly integrates the technology of Google Mesa and Apache Impala, and it based on a column-oriented storage engine and can communicate by MySQL client.
3. User cases
Doris not only provides high concurrent low latency point query performance, but also provides high throughput queries of ad-hoc analysis.
Doris not only provides batch data loading, but also provides near real-time mini-batch data loading.
Doris also provides high availability, reliability, fault tolerance, and scalability.
The simplicity (of developing, deploying and using) and meeting many data serving requirements in single system are the main features of Doris (refer to Overview).
4. Compile and install
Currently support Docker environment and Linux OS: Docker (Linux / Windows / Mac), Ubuntu and CentOS.
4.1 For Docker
Step 1: Install Docker
Take CentOS as an example:
yum -y install docker-io
service docker start
Step 2: Create Docker image for complilation
Given your work space is /my/workspace, and you can download Doris docker file as following:
wget https://github.com/apache/incubator-doris/blob/master/docker/Dockerfile -O /my/workspace/Dockerfile
Now build your image, and it may take a long time (40min to 1 hour)
cd /my/workspace && docker build -t doris-dev:v1.0 .
Step 3: Compile and install Doris
Clone Doris source:
git clone https://github.com/apache/incubator-doris.git /path/to/incubator-doris/
Start a container named doris-dev-test, and map /path/to/incubator-doris/ to /var/local/incubator-doris/ in container.
docker run -it --name doris-dev-test -v /path/to/incubator-doris/:/var/local/incubator-doris/ doris-dev:v1.0
Compile Doris source:
sh build.sh
After successfully building, it will install binary files in the directory output/.
4.2 For Linux
Prerequisites
GCC 5.3.1+, Oracle JDK 1.8+, Python 2.7+, Apache Maven 3.5+, CMake 3.4.3+
- For Ubuntu:
sudo apt-get install g++ cmake zip byacc flex automake libtool binutils-dev libiberty-dev bison python2.7 libncurses5-dev
sudo updatedb
- For CentOS:
sudo yum install gcc-c++ libstdc++-static cmake byacc flex automake libtool binutils-devel bison ncurses-devel
sudo updatedb
If your GCC version is less than 5.3.1, you can run:
sudo yum install devtoolset-4-toolchain -y
and then, set the path of GCC (e.g /opt/rh/devtoolset-4/root/usr/bin) to the environment variable PATH.
Compile and install
Run following script, it will compile thirdparty libraries and build whole Doris.
sh build.sh
After successfully building, it will install binary files in the directory output/.
