Utility class for getting cluster configuration info and suggestions.
Index
class Node
Description
Data class representing a node in a cluster. None
Methods
Node. __init__( self , name: str , roles , ip: str )
class ClusterTopology
Class for creating the best possible configuration for a Node.
Description
The current logic is to try to get to the config: - 2 dedicated cluster manager nodes - 1 voting only data node And create them with the following order: - cm0 - data, voting only - cm1 - data - data
Methods
ClusterTopology. suggest_roles( nodes )
Get roles for a Node, for now, we only focus on the 3 most important roles.
Description
We will do more interesting things with the nodes list, to find the best role. The logic here is: - the first node should be a CM-eligible node, but will add "data" to it - the second node should be a data and voting-only node, so that: - a 2 nodes cluster can function - when a 2CM-eligible node joins, the CM voting can happen immediately - the 3rd one should be a CM-eligible, but will add "data" to it - the +4 nodes should be data etc.
ClusterTopology. remaining_nodes_for_bootstrap( nodes )
Description
Check if cluster is bootstrapped. 2 cm + 1 voting only nodes created. None
ClusterTopology. get_cluster_managers_ips( nodes )
Description
Get the nodes of cluster manager eligible nodes. None
ClusterTopology. get_cluster_managers_names( nodes )
Description
Get the nodes of cluster manager eligible nodes. None
ClusterTopology. nodes_count_by_role( nodes )
Description
Count number of nodes by role. None
