> -----------------------------------------
>
> Key: IGNITE-27855
> URL: https://issues.apache.org/jira/browse/IGNITE-27855
> Project: Ignite
> Issue Type: Improvement
> Components: compute ai3
> Reporter: Pavel Tupitsyn
> Assignee: Vadim Pakhnushev
> Priority: Major
> Labels: ignite-3
> Fix For: 3.2
>
>
> As a user, I want to cancel queries in my compute job when the job is
> cancelled, by passing *JobExecutionContext#cancellationToken* to those
> queries.
> Currently, I have to poll *JobExecutionContext#isCancelled* and manually
> orchestrate cancellation with *CancelHandle* and *CancellationToken*.
> Usage example:
> {code:java}
> private static class CreateTableJob implements ComputeJob<String, Void> {
> @Override
> public CompletableFuture<Void> executeAsync(JobExecutionContext context,
> String tableName) {
> return context.ignite().sql()
> .executeAsync((Transaction) null,
> context.cancellationToken(), "CREATE TABLE " + tableName + "(key BIGINT
> PRIMARY KEY, val INT)")
> .thenApply(x -> null);
> }
> }
> {code}
