Hi as you already noted, ignite cluster has a special node - coordinator, the oldest node in a cluster is coordinator node: ignite.cluster().forServers().forOldest().node()
In case of creation/destroying a cache, coordinator needs to coordinate this process and notify each node about cache creation/destroying. So coordinator indeed does more work than other nodes, but it doesn't significant work so it should not be noticeable for your cluster. However if you create and destroy caches too often then I think this might be noticed, so might be you should clear and re-use existing caches instead of destroying them?
