Alexey Goncharuk commented on IGNITE-3505:
------------------------------------------
Denis,
Looks good to me.
> BinaryObject keys can't be reused because of partition caching.
> ---------------------------------------------------------------
>
> Key: IGNITE-3505
> URL: https://issues.apache.org/jira/browse/IGNITE-3505
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 1.6
> Reporter: Alexei Scherbakov
> Assignee: Denis Magda
> Fix For: 1.7
>
> Attachments: 3505.patch
>
>
> BinaryObject can't be reused as key between caches because it's
> actual implementation BinaryObjectImpl implements KeyCacheObject and
> due to the fact caches partition, which is not recalculated later.
> See
> org.apache.ignite.internal.processors.cache.GridCacheAffinityManager.partition:
> {code}
> if (key instanceof KeyCacheObject && ((KeyCacheObject)key).partition() != -1)
> return ((KeyCacheObject)key).partition();
> {code}
> The issue can be reproduced with the following code:
> {code}
> public static void main(String[] args) throws IgniteException {
> IgniteConfiguration cfg = new IgniteConfiguration();
> cfg.setDiscoverySpi(new TcpDiscoverySpi().setIpFinder(new
> TcpDiscoveryVmIpFinder(true)));
> Ignite ignite = Ignition.start(cfg);
> CacheConfiguration<BinaryObject, BinaryObject> cfg1 = new
> CacheConfiguration<>("Cache 1");
> cfg1.setCacheMode(CacheMode.PARTITIONED);
> cfg1.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
> IgniteCache<BinaryObject, BinaryObject> cache1 =
> ignite.getOrCreateCache(cfg1).withKeepBinary();
> CacheConfiguration<BinaryObject, BinaryObject> cfg2 = new
> CacheConfiguration<>("Cache 2");
> cfg2.setCacheMode(CacheMode.REPLICATED);
>
> cfg2.setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_SYNC);
> IgniteCache<BinaryObject, BinaryObject> cache2 =
> ignite.getOrCreateCache(cfg2);
> BinaryObjectBuilder keyBuilder = ignite.binary().builder("keyType")
> .setField("F1", "V1").hashCode("V1".hashCode());
> BinaryObjectBuilder valBuilder = ignite.binary().builder("valueType")
> .setField("F2", "V2")
> .setField("F3", "V3");
> BinaryObject key = keyBuilder.build();
> BinaryObject val = valBuilder.build();
> cache1.put(key, val);
> cache2.put(key, val); // error
> System.out.println(cache1.get(key)); // error
> System.out.println(cache2.get(key));
> }
> {code}
