Re: Possible optimizations for SQL + Off-heap

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. Sergi 2016-04-21 22:59 GMT+03:00

Re: Documentation for Deployment Modes and Resource Injection

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 Marshaller](doc:binary-marshaller) is used which allows to store cache data in the binary format avoiding necessity to load entries classes from a

Re: Possible optimizations for SQL + Off-heap

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? — Denis > On Apr 21, 2016, at 5:27 PM, Sergi Vladykin

Possible optimizations for SQL + Off-heap

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
