Aleksey Plekhanov commented on IGNITE-14553:
--------------------------------------------
[~korlov] in this case, concurrently updated entries will be lost:
{code:java}
public void testMissedEntries() throws Exception {
IgniteCache<Integer, Integer> cache = client.getOrCreateCache(new
CacheConfiguration<Integer, Integer>("cache")
.setQueryEntities(F.asList(new QueryEntity(Integer.class,
Integer.class).setTableName("t")))
);
for (int i = 0; i < 10_000; i++)
cache.put(i, i);
AtomicBoolean stop = new AtomicBoolean();
GridTestUtils.runAsync(() -> {
while (!stop.get())
cache.put(ThreadLocalRandom.current().nextInt(10_000), 0);
});
assertEquals(10_000, sql("SELECT t._key FROM \"cache\".t").size());
stop.set(true);
}
{code}
