Dmitriy, >> Can you provide a simple example of API calls that will make this possible? API could be like this: 1) via scheduler: Ignite ignite = Ignition.start(....);
ignite.scheduler().schedulel(job, "0 0 * * *"); // This will execute job every day at 00:00 2) via compute Ignite ignite = Ignition.start(....); ignite.compute().schedulel(task, "0 0 * * *"); // This will execute compute task every day at 00:00 Make sense?
