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`, an alert is sent if there is any update in the maximum clique of the graph	BOOL	No	No

Extra Return Attributes

Name	Description	Possible Types
sizeOfMaximumClick	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` an alert is sent if there is any update in the largest connected component of the graph	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.
