No, there still will be a case when BinaryObjectOffHeapImpl is put into
intermediate result set in a query, but concurrently removed and
deallocated from cache and index. Probably we could apply some fancy
technics like reference counting here, but I'm not sure.

Hi Prachi,
Thanks for the useful documentation. I’ve extended it a bit by adding the
following
However, the latter is not the case if [Binary

Sergi,
However if we implement non snapshotable data structure to hold indexes (skip
list or b-tree) then it will be feasible to optimize point 1) - working with
off-heap data with BinaryObjectOffHeapImpl. Am I right?

1. In general it is not possible to keep BinaryObject in "attached" state,
because at the query end we release snapshots and the entry can be
concurrently removed with offheap memory deallocation, while result row is
still needed.
2. Of course there are multiple alternatives (skiplist or b+tree),
Sergi, Igniters,
Big deployments store enormous amount of data in off-heap. If to keep using
such deployments under high load executing SQL queries and basic cache
operations in parallel then it’s easy to see that Java heap pressure grows due
to the bigger number of short live objects creation.
