Dmitry Karachentsev updated IGNITE-3339:
----------------------------------------
Description:
On OFFHEAP_TIERED TRANSACTIONAL cache:
1. Put entry.
2. Cache size equals 1 and iterator returns one entry.
3. Open PESSIMISTIC READ_COMMITED transaction.
4. get() that value.
5. Commit transaction.
6. Cache size now equals 2 and iterator returns two identical entries.
By fast investigation was found that after put() operation value goes to
offheap. After get() operation in explicit transaction the same value appears
in onheap and offheap iterators. As a result user sees two the same entries.
https://github.com/apache/ignite/pull/817
was:
Configure cache as OFFHEAP_TIERED .

> get() in explicit READ_COMMITTED transaction on OFFHEAP_TIERED cache copies
> data from offheap to onheap.
