[jira] [Created] (IGNITE-12142) Ignite ignores that on-heap store
is disabled when putting values through near cache
Bartłomiej Stefański created IGNITE-12142:
---------------------------------------------
Summary: Ignite ignores that on-heap store is disabled when putting values through near cache
Key: IGNITE-12142
URL: https://issues.apache.org/jira/browse/IGNITE-12142
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: 2.7.5, 2.7
Reporter: Bartłomiej Stefański
I have an Ignite cluster that consists of two nodes:
* @n0 - server node
* @n1 - client node
Installed PARTITIONED cache {{myCache}} on both of them. Cache has near cache on client node and disabled on-heap caching on server.
Server configuration:
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="

I have noticed (using visor) strange cache state after putting 20k entries to that cache through client node (@n1):

Why Ignite stores entries on heap space on server node? If I put 20k entries through server node then server on-heap space is not used:
