Denis, it this queue is used in TX caches to resolve rebalancing and
concurrent puts races. We can try removin it once partition gets loaded,
btw. Can you please file a ticket?

Igniters,

As you know there is a property that controls maximum remove queue

history

for atomic caches
(IgniteSystemProperties.IGNITE_ATOMIC_CACHE_DELETE_HISTORY_SIZE).

The strange thing is that this property is also used for transactional
caches as well. I see that GridDhtLocalPartition allocates rmvQueue
regardless of a cache atomicity type which looks confusing.

Do we need to avoid the allocation of the queue for transactional caches?

To get rid of this completely we need to switch to fair
thread-per-partition.
