Using OFF_HEAP_TIERED and Replicated Heap continously grows eventually heap crash

We have a cache configured as Replicated OFF_HEAP_TIERED and when we execute our load test we watch Heap space grow in JConsole to the point where the application becomes unresponsive when it reaches heap limit. We see no signs in JConsole or Cache Metrics that off heap is growing? Here is our tes

Hi, There is no callback out of the box. However, you can probably utilize custom events [1] for this. Use IgniteEvents.recordLocal(..) method to fire an event that will indicate that service is started, and then subscribe for this event as described in documentation. The listener will be your cal

Hi Shawn, Yes, binary format provides direct support for this. You can change the class definition on the client and transparently use the new version. Another option is to use builder [1] to modify the object. [1] https://apacheignite.readme.io/docs/binary-marshaller#modifying-binary-objects-usi

Ok, I understand the bit about the split. So instead of a cluster I now have a bunch of individual nodes all thinking they are the center of the known universe. But why don't they read-through to the database for non-existing data ? (I can understand that the node would avoid read-through for data

Valya, Currently null value is written as one byte, while zero value of long type is written as 9 bytes. I want to improve that and write zeros as one byte as well. As per var-length encoding, I am strongly against it. It saves IO and memory at the cost of CPU. If we encode numbers in this way we
