------------------------------------
Summary: Inefficient memory consumption for checkpoint buffer (was:
inefficient memory consumption for checkpoint buffer)
> Inefficient memory consumption for checkpoint buffer
> ----------------------------------------------------
>
> Key: IGNITE-6210
> URL: https://issues.apache.org/jira/browse/IGNITE-6210
> Project: Ignite
> Issue Type: Bug
> Components: persistence
> Affects Versions: 2.1
> Reporter: Dmitriy Govorukhin
> Assignee: Dmitriy Govorukhin
> Priority: Critical
> Fix For: 2.3
>
>
> Current implementation allows configure checkpoint buffer size in
> PersistentStoreConfiguration, but checkpoint buffer will be created for each
> memory configuration with size equals the one indicated in
> PersistentStoreConfiguration.
> For example:
> {code}
> PersistentStoreConfiguration prCfg = new
> PersistentStoreConfiguration();
> prCfg.setCheckpointingFrequency(5L * 1024L * 1024L * 1024L); // 5GB.
> MemoryConfiguration memCfg = new MemoryConfiguration();
> MemoryPolicyConfiguration pl1 = new MemoryPolicyConfiguration();
> pl1.setMaxSize(100L * 1024L * 1024L); // 100 Mb.
> MemoryPolicyConfiguration pl2 = new MemoryPolicyConfiguration();
> pl2.setMaxSize(10L * 1024L * 1024L * 1024L); // 10GB.
> memCfg.setMemoryPolicies(pl1, pl2);
> {code}
> pl1(max size 10Gb) will be have checkpoint buffer = 5GB and pl2(max size
> 100Mb) buffer= 5GB
