--------------------------------------
Assignee: Sisko (was: Yakov Zhdanov)
> Add warning / suggestion if cache.storeValueBytes == true
> ---------------------------------------------------------
>
> Key: IGNITE-88
> URL: https://issues.apache.org/jira/browse/IGNITE-88
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: sprint-1
> Reporter: Alexey Kuznetsov
> Assignee: Sisko
> Fix For: sprint-1
>
>
> If cache configured with storeValueBytes that will lead to double memory
> consumption: for object itself and its value bytes.
> Consider following example:
> 1. Start one node with 1G memory.
> 2. Fill cache to get all most free memory. Node works as expected.
> 3. Start one more node with same config as first node (with 1G memory).
> 4. Preloading from first to second node will start, BUT because of
> storeValueBytes option second node actually need 2G memory. And after short
> time huge GC will start on second node and it will became almost non
> operational.
> So, we need a warning / suggestion if cache configured with storeValueBytes .
