Pavel Tupitsyn updated IGNITE-26892:
------------------------------------
Description:
h1. Motivation
As a user, I want to leverage DNS to keep the client connected to all cluster
nodes, even in the face of topology changes.
h1. Requirements
1. When a host name is provided in IgniteClientConfiguration#addresses, the
client should resolve it and use all returned IPs as potential node addresses
2. Resolve all known host names again and connect to newly discovered addresses:
- On any connection error (might indicate node failure)
- On primary replica change (might indicate topology change)
- On timer (to handle DNS caching)
