HugeGraph-Hubble Quick Start

1 HugeGraph-Hubble Overview

Note: The current version of Hubble has not yet added Auth/Login related interfaces and standalone protection, it will be added in the next Release version (≥ 1.5). Please be careful not to expose it in a public network environment or untrusted networks to avoid related SEC issues (you can also use IP & port whitelist + HTTPS)

HugeGraph-Hubble is HugeGraph’s one-stop visual analysis platform. The platform covers the whole process from data modeling, to efficient data import, to real-time and offline analysis of data, and unified management of graphs, realizing the whole process wizard of graph application. It is designed to improve the user’s use fluency, lower the user’s use threshold, and provide a more efficient and easy-to-use user experience.

The platform mainly includes the following modules:

Graph Management

The graph management module realizes the unified management of multiple graphs and graph access, editing, deletion, and query by creating graph and connecting the platform and graph data.

Metadata Modeling

The metadata modeling module realizes the construction and management of graph models by creating attribute libraries, vertex types, edge types, and index types. The platform provides two modes, list mode and graph mode, which can display the metadata model in real time, which is more intuitive. At the same time, it also provides a metadata reuse function across graphs, which saves the tedious and repetitive creation process of the same metadata, greatly improves modeling efficiency and enhances ease of use.

Graph Analysis

By inputting the graph traversal language Gremlin, high-performance general analysis of graph data can be realized, and functions such as customized multidimensional path query of vertices can be provided, and three kinds of graph result display methods are provided, including: graph form, table form, Json form, and multidimensional display. The data form meets the needs of various scenarios used by users. It provides functions such as running records and collection of common statements, realizing the traceability of graph operations, and the reuse and sharing of query input, which is fast and efficient. It supports the export of graph data, and the export format is Json format.

Task Management

For Gremlin tasks that need to traverse the whole graph, index creation and reconstruction, and other time-consuming asynchronous tasks, the platform provides corresponding task management functions to achieve unified management and result viewing of asynchronous tasks.

Data Import

“Note: The data import function is currently suitable for preliminary use. For formal data import, please use hugegraph-loader, which has much better performance, stability, and functionality.”

Data import is to convert the user’s business data into the vertices and edges of the graph and insert it into the graph database. The platform provides a wizard-style visual import module. By creating import tasks, the management of import tasks and the parallel operation of multiple import tasks are realized. Improve import performance. After entering the import task, you only need to follow the platform step prompts, upload files as needed, and fill in the content to easily implement the import process of graph data. At the same time, it supports breakpoint resuming, error retry mechanism, etc., which reduces import costs and improves efficiency.

2 Deploy

There are three ways to deploy hugegraph-hubble

• Use Docker (Convenient for Test/Dev)
• Download the Toolchain binary package
• Source code compilation

2.1 Use docker (Convenient for Test/Dev)

Special Note: If you are starting hubble with Docker, and hubble and the server are on the same host. When configuring the hostname for the graph on the Hubble web page, please do not directly set it to localhost/127.0.0.1. This will refer to the hubble container internally rather than the host machine, resulting in a connection failure to the server.

If hubble and server is in the same docker network, we recommend using the container_name (in our example, it is server) as the hostname, and 8080 as the port. Or you can use the host IP as the hostname, and the port is configured by the host for the server.

We can use docker run -itd --name=hubble -p 8088:8088 hugegraph/hubble to quick start hubble.

Alternatively, you can use Docker Compose to start hubble. Additionally, if hubble and the graph are in the same Docker network, you can access the graph using the container name of the graph, eliminating the need for the host machine’s IP address.

Use docker-compose up -d，docker-compose.yml is following:

version: '3'
services:
  server:
    image: hugegraph/hugegraph
    container_name: server
    ports:
      - 8080:8080

  hubble:
    image: hugegraph/hubble
    container_name: hubble
    ports:
      - 8088:8088

Note:

1. The docker image of hugegraph-hubble is a convenience release to start hugegraph-hubble quickly, but not official distribution artifacts. You can find more details from ASF Release Distribution Policy.

2. Recommand to use release tag(like 1.2.0) for the stable version. Use latest tag to experience the newest functions in development.

2.2 Download the Toolchain binary package

hubble is in the toolchain project. First, download the binary tar tarball

wget https://downloads.apache.org/incubator/hugegraph/{version}/apache-hugegraph-toolchain-incubating-{version}.tar.gz
tar -xvf apache-hugegraph-toolchain-incubating-{version}.tar.gz 
cd apache-hugegraph-toolchain-incubating-{version}.tar.gz/apache-hugegraph-hubble-incubating-{version}

Run hubble

bin/start-hubble.sh

Then, we can see:

starting HugeGraphHubble ..............timed out with http status 502
2023-08-30 20:38:34 [main] [INFO ] o.a.h.HugeGraphHubble [] - Starting HugeGraphHubble v1.0.0 on cpu05 with PID xxx (~/apache-hugegraph-toolchain-incubating-1.0.0/apache-hugegraph-hubble-incubating-1.0.0/lib/hubble-be-1.0.0.jar started by $USER in ~/apache-hugegraph-toolchain-incubating-1.0.0/apache-hugegraph-hubble-incubating-1.0.0)

2023-08-30 20:38:41 [main] [INFO ] o.a.h.HugeGraphHubble [] - Started HugeGraphHubble in 7.379 seconds (JVM running for 8.499)

Then use a web browser to access ip:8088 and you can see the Hubble page. You can stop the service using bin/stop-hubble.sh.

2.3 Source code compilation

Note: Compiling Hubble requires the user’s local environment to have Node.js V16.x and yarn installed.

apt install curl build-essential
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
source ~/.bashrc
nvm install 16

Then, verify that the installed Node.js version is 16.x (please note that higher Node version may cause conflicts).

node -v

install yarn by the command below:

npm install -g yarn

Download the toolchain source code.

git clone https://github.com/apache/hugegraph-toolchain.git

Compile hubble. It depends on the loader and client, so you need to build these dependencies in advance during the compilation process (you can skip this step later).

cd incubator-hugegraph-toolchain
sudo pip install -r hugegraph-hubble/hubble-dist/assembly/travis/requirements.txt
mvn install -pl hugegraph-client,hugegraph-loader -am -Dmaven.javadoc.skip=true -DskipTests -ntp
cd hugegraph-hubble
mvn -e compile package -Dmaven.javadoc.skip=true -Dmaven.test.skip=true -ntp
cd apache-hugegraph-hubble-incubating*

Run hubble

bin/start-hubble.sh -d
