Maksim Timonin updated IGNITE-13796:
------------------------------------
Description:
Docs related to the ticket IGNITE-13204. Before this change it was impossible
to rely on partition awareness feature [1] on thin clients within Kubernetes
environment. The reason was a Kubernetes cluster can scale dynamically but thin
client was able to configure only static list of addresses in moment of start.
The ticket fix it, provide opportunity to dynamically change list of addresses
known to thin clients. That ticket relates only to thin clients started
*within* Kubernetes cluster. Thin clients that are running outside of
Kubernetes cluster must be configured the same way as before (with static list
of addresses, usually it is an address of Ingress or other load balancer), it's
impossible to provide partition awareness feature for them as there are no
directly access to pods.
The ticket:
1. Introduced class KubernetesConnectionConfiguration that represents common
settings to connect within Kubernetes cluster.
2. There are 2 classes that use the configuration class to configure the
connection:
* TcpDiscoveryKubernetesIpFinder is responsible to configure Ignite nodes.
* ThinClientKubernetesAddressFinder is responsible to configure Thin clients
in case when partition awareness feature is enabled.
There was a refactoring of TcpDiscoveryKubernetesIpFinder to enable to use it
this configuration class, so some methods of the Finder are marked as
deprecated.
