----------------------------------------
Summary: DirectMemoryRegion: Introduce checkpoint buffer configuration and improve logging o start
Key: IGNITE-8536
URL: https://issues.apache.org/jira/browse/IGNITE-8536
Project: Ignite
Issue Type: Improvement
Components: persistence
Affects Versions: 2.4
Reporter: Alexey Kuznetsov
Assignee: Alexey Goncharuk
We need to configure data region checkpoint buffer size when we start Ignite on computer with limiter resources, for example AWS t2.micro
In current implementation Ignite will allocate 100Mb buffers, it should be configurable.
Also we need to improve message printed in log:
current message:
{code}
[2018-05-18T03:43:01,449][INFO ][exchange-worker-#51][PageMemoryImpl] Started page memory [memoryAllocated=100.0 MiB, pages=24937, tableSize=1.4 MiB, checkpointBuffer=100.0 MiB]
{code}
Lets add region name and rename "checkpointBuffer" to "data region buffer".
