Re: Help with affinityRun on collocated ignite queue

[Ilya Kasnacheev]

Hello!

I don't understand your question. A collocated queue is located on a single
node, but you still need a method to run code on that specific node, don't
you?

The benefit is presumably shorter round-trip times.

Help with affinityRun on collocated ignite queue

[ps594]

I am trying to understand the use case of  affinityRun / affinityCall

  
methods of IgniteQueue interface. Even after delving into documentation I
could not understand a good use case why would we want to run jobs on the
collocated queue using affinityRun method of queue interface, since
collocated queues are on the same node why can't I simply write my own
lambda function. Specifically what benefits does the affinityRun offers for
ignite queue (given affinityRun method is not supported for non-collocated
queues)?
