Privilege

Overview

Privileges are a fundamental access control mechanism that define the operations a user is authorized to perform within a database. They play a critical role in enforcing security by restricting access to specific actions, such as querying data, modifying records, or administering the system. Privileges can be granted to roles (or policies), or assigned directly to individual users.

Ultipa defines privileges at three levels—System, Graph, and Property—to support fine-grained access control.

Showing Privileges

To list all defined graph and system privileges:

show().privilege()

This will return a table _privilege, as shown below:

`SHOW_BACKUP`	Shows backups of the database.
`CREATE_BACKUP`	Creates backups for the database.

Graph Privileges

Graph privileges govern operations related to accessing and modifying the data and structure of specific graphs. They also include permissions for managing associated elements such as indexes, jobs, and HDC graphs.

Ultipa supports the following graph privileges:

Privilege	Description
`READ`	Reads data from graphs.
`INSERT`	Inserts nodes and edges into graphs.
`UPSERT`	Updates or inserts nodes and edges in graphs.
`UPDATE`	Updates nodes and edges in graphs.
`DELETE`	Deletes nodes and edges in graphs.
`CREATE_SCHEMA`	Creates schemas in graphs.
`DROP_SCHEMA`	Drops schemas in graphs.
`ALTER_SCHEMA`	Alters schemas in graphs.
`SHOW_SCHEMA`	Shows schemas in graphs.
`RELOAD_SCHEMA`	Reloads the total number of nodes and edges in graphs.
`CREATE_PROPERTY`	Creates properties in graphs.
`DROP_PROPERTY`	Drops properties in graphs.
`ALTER_PROPERTY`	Alters properties in graphs.
`SHOW_PROPERTY`	Shows properties in graphs.
`CREATE_FULLTEXT`	Creates full-text indexes in graphs.
`DROP_FULLTEXT`	Drop full-text indexes in graphs.
`SHOW_FULLTEXT`	Shows full-text indexes in graphs.
`CREATE_VECTOR_INDEX`	Creates vector indexes in graphs.
`DROP_VECTOR_INDEX`	Drop vector indexes in graphs.
`SHOW_VECTOR_INDEX`	Shows vector indexes in graphs.
`CREATE_INDEX`	Creates indexes in graphs.
`DROP_INDEX`	Drops indexes in graphs.
`SHOW_INDEX`	Shows indexes in graphs.
`LTE`	Loads properties from disk into the computing engine.
`UFE`	Unloads properties from the computing engine.
`CLEAR_JOB`	Clear jobs in graphs.
`STOP_JOB`	Stops jobs in graphs.

`CREATE_HDC_GRAPH`	Creates HDC graphs.
`SHOW_HDC_GRAPH`	Shows HDC graphs.
`DROP_HDC_GRAPH`	Drops HDC graphs.
`COMPACT_HDC_GRAPH`	Compacts HDC graphs.

Property Privileges

Property privileges provide more granular control over read and write permissions to specific properties within graphs. If no property privileges are explicitly defined, all properties are granted read and write permissions by default.

Ultipa supports the following property privileges:

Privilege	Description
`READ`	Grants permission to read certain properties in graphs.
`WRITE`	Grants permission to read and write certain properties in graphs.
`DENY`	Explicitly denies read and write access to certain properties. If both `DENY` and `READ` (or `WRITE`) are assigned to a property, `DENY` takes precedence.

If the READ privilege for the name property of the user nodes is not granted:

Operation	Examples
Return the property	`MATCH (n:user) RETURN n` This GQL query excludes the `name` property from the returned node information. `MATCH (n:user) RETURN n.name` This GQL query throws an error as you cannot read the `name` property.
Filter the property	`MATCH (n:user {name: "johndoe"}) RETURN n` This GQL query throws an error as you cannot read the `name` property.
Export	You cannot export the properties which you cannot read.

If the WRITE privilege for the name property of the user nodes is not granted:

Operation	Examples
Insert	`INSERT (:user {_id: "U873", name:"johndoe"})` This GQL query throws an error as you cannot write the `name` property.
Update	`MATCH (n:user {_id: "U873"}) SET n.name = "johndoe"` This GQL query throws an error as you cannot write the `name` property.
Delete	You can still delete properties from the graph structure even if you don't have corresponding `WRITE` property privilege, but it requires the `DROP_PROPERTY` graph privilege.
