Graph¶

maximumClique (Stream Processor)¶

This extension returns the size of the maximum clique of a graph.

Syntax

graph:maximumClique(<STRING> main.vertex, <STRING> refer.vertex, <BOOL> notify.update)

QUERY PARAMETERS

Name	Description	Possible Data Types	Optional	Dynamic
main.vertex	This is the ID of the main vertex that is used to create a graph.	STRING	No	No
refer.vertex	This is the ID of the 'refer vertex' that connects with the main vertex in thegraph.	STRING	No	No
notify.update	If this is set to `true` and if there is any update in the maximum clique of the graph, an alert is sent.	BOOL	No	No

Extra Return Attributes

Name	Description	Possible Types
sizeOfMaximumClick	The size of the maximum clique of the graph.	INT

Examples EXAMPLE 1

define stream CseEventStream (vertex1 String, vertex2 String); 
from CseEventStream#graph:maximumClique(vertex1,vertex2,false)  
select maximumClique  
insert all events into OutputStream;

This query returns the maximum clique of a given graph.

sizeOfLargestConnectedComponent (Stream Processor)¶

This extension returns the size of the largest connected component of a graph.

Syntax

graph:sizeOfLargestConnectedComponent(<STRING> main.vertex, <STRING> refer.vertex, <BOOL> notify.update)

QUERY PARAMETERS

Name	Description	Possible Data Types	Optional	Dynamic
main.vertex	This is the ID of the main vertex that is used to create the graph.	STRING	No	No
refer.vertex	This is the ID of the 'refer vertex' that connects with the main vertex in the graph.	STRING	No	No
notify.update	If this is set to `true` and if there is any update in the largest connected component of the graph, an alert is sent.	BOOL	No	No

Extra Return Attributes

Name	Description	Possible Types
sizeOfLargestConnectedComponent	The size of the largest connected component of a graph.	LONG

Examples EXAMPLE 1

define stream CseEventStream (vertex1 String, vertex2 String); 
from CseEventStream#graph:sizeOfLargestConnectedComponent(vertex1,vertex2,false) 
select sizeOfLargestConnectedComponent 
insert all events into OutputStream ;

This query returns the size of the largest connected component of a given graph.
