Sergey Kosarev updated IGNITE-11909:
------------------------------------
Description:
Preconditions:
1) AtomicityMode.Transactional
2) Key is custom object. (i.e MyKey)
cache.returnAll returns should return Map<MyKey, EntryProcessorResult<T>>, but
keys
processed on remote node(s) are not unwrapped and return as BinaryObject, so we
can gat a map with mixed keys:
{code}
key.class = BinaryObjectImpl, key =
org.apache.ignite.examples.datagrid.CacheEntryProcessorExample2$MyKey
[idHash=151593342, hash=31459296, i=2]
key.class = MyKey, key = MyKey{i=7}
key.class = BinaryObjectImpl, key =
org.apache.ignite.examples.datagrid.CacheEntryProcessorExample2$MyKey
[idHash=405215542, hash=31638042, i=8]
key.class = MyKey, key = MyKey{i=1}
key.class = BinaryObjectImpl, key =
org.apache.ignite.examples.datagrid.CacheEntryProcessorExample2$MyKey
[idHash=1617838096, hash=31548669, i=5]
key.class = MyKey, key = MyKey{i=0}
key.class = BinaryObjectImpl, key =
org.apache.ignite.examples.datagrid.CacheEntryProcessorExample2$MyKey
[idHash=138776324, hash=31578460, i=6]
key.class = MyKey, key = MyKey{i=9}
key.class = MyKey, key = MyKey{i=4}
{code}
