-----------------------------------------

             Summary: Transactional putAll - significant performance drop on big batches of entries.
                 Key: IGNITE-12087
                 URL: https://issues.apache.org/jira/browse/IGNITE-12087
             Project: Ignite
          Issue Type: Bug
          Components: cache
            Reporter: Pavel Pereslegin


After IGNITE-5227 have been fixed I found significant performance drop in putAll operation.

Insertion of 30_000 entries before IGNITE-5227 took ~1 second.
After IGNITE-5227 - 130 seconds (~100x slower).

I checked a different batch size:
10_000 - 10 seconds
20_000 - 48 seconds
30_000 - 130 seconds

and I was not able to wait for the result of 100_000 entries.

Reproducer
{code:java}
public class CheckPutAll extends GridCommonAbstractTest {
    @Override protected IgniteConfiguration getConfiguration(String igniteInstanceName) throws Exception {
        IgniteConfiguration cfg = super.getConfiguration(igniteInstanceName);

        CacheConfiguration ccfg = new CacheConfiguration(DEFAULT_CACHE_NAME);

        ccfg.setAtomicityMode(TRANSACTIONAL);

        cfg.setCacheConfiguration(ccfg);

        return cfg;
    }

    @Test
    public void check() throws Exception {
        int cnt = 30_000;

        // Prepare data.
        Map<Integer, Integer> data = new HashMap<>(U.capacity(cnt));

        for (int i = 0; i < cnt; i++)
            data.put(i, i);

        // Start 1 node.
        Ignite node0 = startGrid(0);

        node0.cluster().active(true);

        node0.cluster().baselineAutoAdjustTimeout(0);

        IgniteCache<Integer, Integer> cache0 = node0.cache(DEFAULT_CACHE_NAME);

        // Load data.
        cache0.putAll(data);
    }
}{code}
