Abstract

Using collaborative triggers within a distributed computing system can include, in response to detecting a first event of a selected type within a first node of the computing system, generating a first collaborative trigger having a query identifier correlated with the selected type of the event and distributing the first collaborative trigger through other nodes of the computing system so that the first collaborative trigger reaches an actor of the computing system. The computer-implemented method can include suppressing, within each node that distributes the first collaborative trigger, each other collaborative trigger having a same query identifier as the first collaborative trigger until a response to the first collaborative trigger is received from the actor.

Claims

1. A distributed computing system, comprising:

a plurality of nodes; and

an actor;

wherein the plurality of nodes are configured to initiate operations including;

generating, in response to detecting an event of a selected type, a first collaborative trigger having a query identifier configured to indicate the selected type of the event;

distributing the first collaborative trigger through other ones of the plurality of nodes so that the first collaborative trigger reaches the actor;

receiving, subsequent to the distributing and from the actor, a response to the first collaborative trigger; and

suppressing, prior to the receiving and within each of the nodes that distributes the first collaborative trigger, each other collaborative trigger having a same query identifier as the first collaborative trigger until the response to the first collaborative trigger is received from the actor;

wherein the actor is configured to initiate operations including;

generating the response to the first collaborative trigger, and

forwarding the response to the plurality of nodes.

2. The distributed computing system of claim 1, wherein

the suppressing comprises:

in response to detecting a second event of the selected type, preventing generation of a second collaborative trigger corresponding to the second event.

3. The distributed computing system of claim 1, further comprising, for each of the nodes that distributes the first collaborative trigger:

in response to receiving the response from the actor to the first collaborative trigger, discontinuing the suppressing of each other collaborative trigger having the same query identifier as the first collaborative trigger.

4. The distributed computing system of claim 1, wherein

the suppressing comprises:

within each of the nodes that distributes the first collaborative trigger, adding an entry to a collaborative trigger table, wherein

the entry specifies the query identifier of the first collaborative trigger.

5. The distributed computing system of claim 4, wherein

the suppressing comprises, for each of the nodes that distributes the first collaborative trigger:

in response to receiving a second collaborative trigger, comparing a query identifier of the second collaborative trigger with each query identifier stored in the collaborative trigger table; and

in response to matching the query identifier of the second collaborative trigger with one of the query identifiers stored in the collaborative trigger table, preventing the second collaborative trigger from propagating to another node of the distributed computing system.

6. The distributed computing system of claim 4, wherein

the suppressing comprises, for each of the nodes that distributes the first collaborative trigger:

in response to detecting a second event, determining a query identifier correlated with a type of the second event;

comparing the query identifier correlated with the second event with each query identifier stored in the collaborative trigger table; and

in response to matching the query identifier correlated with the second event with one of the query identifiers stored in the collaborative trigger table, preventing generation of a second collaborative trigger corresponding to the second event.

7. The distributed computing system of claim 4, further comprising, for each of the nodes that distributes the first collaborative trigger:

removing the entry specifying the query identifier of the first collaborative trigger from the collaborative trigger table in response to receiving the response to the first collaborative trigger.

8. A computer program product, comprising:

a computer readable storage medium having program instructions embodied therewith,

the program instructions executable by one or more processors to cause the one or more processors to initiate following operations;

generating, in response to detecting a first event of a selected type within a first node of a distributed computing system, a first collaborative trigger having a query identifier configured to indicate the selected type of the event;

distributing the first collaborative trigger through other nodes of the computing system so that the first collaborative trigger reaches an actor of the distributed computing system;

receiving, subsequent to the distributing and from the actor, a response to the first collaborative trigger; and

suppressing, prior to the receiving and within each node that distributes the first collaborative trigger, each other collaborative trigger having a same query identifier as the first collaborative trigger until the response to the first collaborative trigger is received from the actor, wherein

the actor is configured to initiate operations including;

generating the response to the first collaborative trigger, and

forwarding the response to the other nodes.

9. The computer program product of claim 8, wherein

the suppressing comprises:

in response to detecting a second event of the selected type, preventing generation of a second collaborative trigger corresponding to the second event.

10. The computer program product of claim 8, wherein

the program instructions are executable by the one or more processors to cause the one or more processors to initiate operations comprising, for each of the nodes that distributes the first collaborative trigger:

in response to receiving the response from the actor node to the first collaborative trigger, discontinuing the suppressing of each other collaborative trigger having the same query identifier as the first collaborative trigger.

11. The computer program product of claim 8, wherein

the suppressing comprises:

within each of the nodes that distributes the first collaborative trigger, adding an entry to a collaborative trigger table, wherein

the entry specifies the query identifier of the first collaborative trigger.

12. The computer program product of claim 11, wherein

the suppressing comprises, for each of the nodes that distributes the first collaborative trigger:

in response to receiving a second collaborative trigger, comparing a query identifier of the second collaborative trigger with each query identifier stored in the collaborative trigger table; and

in response to matching the query identifier of the second collaborative trigger with one of the query identifiers stored in the collaborative trigger table, preventing the second collaborative trigger from propagating to another node of the distributed computing system.

13. The computer program product of claim 11, wherein

the suppressing comprises, for each of the nodes that distributes the first collaborative trigger:

in response to detecting a second event, determining a query identifier correlated with a type of the second event;

comparing the query identifier correlated with the second event with each query identifier stored in the collaborative trigger table; and

in response to matching the query identifier correlated with the second event with one of the query identifiers stored in the collaborative trigger table, preventing generation of a second collaborative trigger corresponding to the second event.
