Apache Doris (incubating)

Doris is an MPP-based interactive SQL data warehousing for reporting and analysis. It open-sourced by Baidu.

1. License

Apache License, Version 2.0

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 only supports Docker environment and Linux OS, such as 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 OS

Prerequisites

You must be install following softwares:

GCC 5.3.1+, Oracle JDK 1.8+, Python 2.7+, Apache Maven 3.5+, CMake 3.4.3+

After you installed above all, you also must be set them to environment variable PATH and set JAVA_HOME.

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/.
