---------------------------------------
Summary: Exponential putAll performance degradation in
transactional cache
Key: IGNITE-14076
URL: https://issues.apache.org/jira/browse/IGNITE-14076
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: 2.9.1
Reporter: Pavel Tupitsyn
Fix For: 2.11
{{putAll}} execution time grows almost exponentially while the number of keys
grows linearly in the following test:
{code:java}
public class PutAllTxTest extends GridCommonAbstractTest {
@Test
public void testPutAll() throws Exception {
Ignition.start(getConfiguration("server1"));
Ignition.start(getConfiguration("server2"));
Ignite ignite =
Ignition.start(getConfiguration("client").setClientMode(true));
IgniteCache<Integer, Integer> cache = ignite.createCache(
new CacheConfiguration<Integer, Integer>("c")
.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL));
int count = 50000;
Map<Integer, Integer> data = new TreeMap<>();
for (int i = 0; i < count; i++)
data.put(i, i);
long begin = System.nanoTime();
cache.putAll(data);
long dur = System.nanoTime() - begin;
System.out.println(">>>>> " + dur / 1000000);
}
}
{code}
