Hello. I would like to run task on all nodes with specified cache or all partitions of specified cache and throw exception if some node is offline. I use this code:
private ClusterGroup getCacheClusterGroup() { Set<Object> baselineConsitentIds = ignite .cluster() .currentBaselineTopology() .stream() .map(n -> n.consistentId()) .collect(toSet()); ClusterGroup cacheClusterGroup = ignite .cluster() .forCacheNodes("test_cache"); cacheClusterGroup .nodes() .forEach(n -> baselineConsitentIds.remove(n.consistentId())); if (!baselineConsitentIds.isEmpty()) { throw new IllegalStateException("Some Ignite baseline nodes are offline: " + baselineConsitentIds); } return cacheClusterGroup; } ignite .compute(getCacheClusterGroup()) .broadcast(job) Is it good solution? May be someone knows something better... Thank you.
