When Ignite allocated next memory segment?

I use embedded apache ignite in spring.
Once I test stress test, TPS is temporarily drop down when appearing below log. 

a.i.i.p.impl.PageMemoryNoStoreImpl : Allocted next memory segment [plcName=default, chunkSize=422.2MB

I guess the memory configuration is needed.
so I configure systemCacheMaxSize and systemCacheInitialSize, but not changed

My application is need stable tps guarantee.

How can I fix it?

Thanks

Solution

  • I solved It.

    I needed MemoryPolicyConfiguration.

    Here are my solutions. 

    new MemoryConfiguration()
    .setMemoryPolicies(new MemoryPolicyConfiguration()
        .setInitialSize(initSizeMb * 1024L * 1024)
        .setMaxSize(maxSizeMb * 1024L * 1024L))
