Re: Expose service deployed on service node in ignite via REST

So lets say I create a compute task extending compute-task-split-adapter and I write my code inside split and reduce methods. After that is it enough just to package my file as jar and place in libs folder of ignite installation , for the rest api to recognize. Ex : / public class MyComputeTask

Re: Expose service deployed on service node in ignite via REST

Zaheer, There is an embedded REST processor in Ignite. It doesn't have a direct way to call service methods. But you can execute compute tasks via REST, and you may use it to call services. Another option is to write a custom REST controller and write your custom logic in it. That's what you

Guarantees of CacheQueryEntryEvent.getPartitionUpdateCounter()

Hi, I would like to ask what guarantees CacheQueryEntryEvent.getPartitionUpdateCounter() provides. Can I assume that within a single partition: 1. They are unique. 2. They are consumed sequentially in the increasing order. 3. They are consecutive numbers - there are no gaps even in case of node

Hello! I don't really understand why you add extra condition to join and get more records, not fewer. Can you analyze those 66 records, try to find something in common. Then do the same for records that did not show up, try to understand how they are different from the previous ones. Regards,

Re: Expose service deployed on service node in ignite via REST

Zaheer, Does it have to be a service? Won't a compute task be enough? You can use an execute REST command to run a compute task on a grid. You may either modify the cache or call a service from this task. Denis чт, 13 дек. 2018 г. в
