Summary: Detecting low memory on ignite node startup
Key: IGNITE-6003
URL: https://issues.apache.org/jira/browse/IGNITE-6003
Project: Ignite
Issue Type: Improvement
Reporter: Sergey Chugunov
h2. Motivation
Starting from version 2.0 Ignite keeps all data offheap and allocates it on
startup based on MemoryPolicy settings.
So several Ignite nodes started on the same machine may allocate an order of
magnitude more memory than physically available so when putting pressure on
such cluster will cause the machine to hang.
h2. Acceptance Criteria
# Reliable cross-platform algorithm to detect low memory is developed.
# Ignite node fails to start with descriptive error message when the algorithm
detects low memory which may cause hang.
