Pavel,
it's correct behaviour. See simple test case for illustration:
IgniteCache cache = grid(0).cache(null);
long cnt = 0;
while (true) {
cache.put(cnt++, 1);
Thread.sleep(1000); // Waiting for heartbeat message and
metrics update
CacheMetrics metrics = cache.metrics();
assertEquals(cnt, metrics.getCachePuts());
}
This cycle will run infinitely because cache.metrics() returns data for one
particular cache node and amount of puts and iterations are equal.
If we change the code above and will get metrics for cluster group (e.g.
CacheMetrics metrics =
cache.metrics(grid(0).cluster().forCacheNodes(null))) then test will fail
because each put operation actually performs on primary node and on every
backup node. In this case getCachePuts() returns sum of put operation for
all cache nodes.
