-----------------------------------------
Summary: In-memory cache should use BLAT as their Affinity Topology
Key: IGNITE-8414
URL: https://issues.apache.org/jira/browse/IGNITE-8414
Project: Ignite
Issue Type: Improvement
Reporter: Eduard Shangareev
Assignee: Eduard Shangareev
Now in-memory caches use all active server nodes as affinity topology and it
changes with each node join and exit. What differs from persistent caches
behavior which uses BLAT (BaseLine Affinity Topology) as their affinity
topology.
It causes problems:
- we lose (in general) co-location between different caches;
- we can't avoid PME when a non-BLAT node joins cluster;
- implementation should consider 2 different approaches to affinity
calculation.
To handle these problems we should make in-memory and persistent cache work
similar.
