TigerGraph Datasource Integration

Knowi enables visualization, warehousing, and reporting automation from TigerGraph along with other structured and unstructured datasources.

Overview

Connect, extract, and transform data from your TigerGraph database, using the query generation capabilities of Knowi to write your queries. You can also make use of Cloud9Agent. This can securely pull data inside your network. See agent configuration for more details.

Add TigerGraph Datasource

  1. Log in to Knowi and select Queries from the left sidebar.

  2. Click on New Datasource + button and select TigerGraph from the list of datasources.

  3. After navigating to the New Datasource page, follow the prompts and configure the following details to set up connectivity to your own TigerGraph database:

    a. Datasource Name: Enter a name for your datasource

    b. Host Name: Enter the hostname to connect to

    c. Port: Enter the database port

    d. Database Name: Enter the name of the database

    e. User: Enter the User ID to connect

    f. Password: Enter the password to connect to the database

    g. Request Token URL: Optional. The endpoint to call to exchange the secret key to access the token, could be used instead of a user name and password pair. May include a secret key and other options

    h. Request Token POST: Check this box (defaults to GET otherwise) if the request token URL need to be called with the POST method. Add in any data payloads expected, which may include a secret key

  4. Establish Network connectivity and click on the Test Connection button.

    Note: The connection validity of the network can be tested only if it has been established via Direct Connectivity or an SSH tunnel. For more information on connectivity and datasource, please refer to the documentation on- Connectivity & Datasources.

  5. Click on Save and start Querying.

Query TigerGraph Datasource

The TigerGraph Datasource can be queried in seven different ways:

Run Installed Query

This query mode runs a TigerGraph-installed query which is possible to select from a list of installed queries and pass parameters to the query. This is the most efficient way.

Note: The options available may change depending on the metric you select.

Query Type: Select the query type

Installed Query: Select a query from the list of installed queries to run

Run Parameters: List of parameters to run a query.

Here is an example of using an installed query against TigerGraph Datasource:

RIQ parameters

Click on the Preview button to analyze the results of your Query and fine-tune the desired output, if required.

Below are the preview results of the Query based on the above example.

RIQ parameters

Run Interpreted Query

This query mode runs a TigerGraph query which is not installed. It can be typed right into Knowi UI with parameters.

Note: The options available may change depending on the metric you select.

Query Type: Select the query type

Run Parameters: List of parameters to run a query.

Here is an example of a Query made against TigerGraph Datasource:

RINTR parameters

Click on the Preview button to analyze the results of your Query and fine-tune the desired output, if required.

Run Built-in Function

This query mode runs a TigerGraph built-in function. More details at the TigerGraph docs.

Note: The options available may change depending on the metric you select.

Query Type: Select the query type

Built-in Function Type: Select the built-in function kind

Vertex Type: Select vertex type

Expand Results

It does the expanding of data returned by the Tigergraph server. It is set by default. With this Expand, it allows you to easily see the output content in the grid and filter on fields.

Though plotting the graph chart is allowed with any data, expanded or not expanded.

Data Execution Strategy

Define data execution strategy by using any of the following two options:

Non-direct execution can be put into action if you choose to run the Query once or at scheduled intervals. For more information, feel free to check out this documentation- Defining Data Execution Strategy

Create Dataset

The result of your Query is called Dataset. After reviewing the results, name your dataset and then hit the Create & Run button.
