MemoryDiscovery

Discovery service that keeps connections in memory.

Inherits: IDiscovery, IReconfigurable

Description

The MemoryDiscovery class allows you to create discovery services that keep connections in memory.

Configuration parameters

  • [connection key 1]:
  • : connection parameters for key 1
  • [connection key 2]:
  • : connection parameters for key N

Constructors

Creates a new instance of this class.

public MemoryDiscovery(ConfigParams config = null)

  • config: ConfigParams - (optional) configuration with connection parameters.

Creates a new instance of this class.

public MemoryDiscovery()

Instance methods

Configure

Configures a component by passing its configuration parameters.

public virtual void Configure(ConfigParams config)

  • config: ConfigParams - configuration parameters to be set.

ReadConnections

Reads connections from configuration parameters. Each section represents an individual Connection params.

private void ReadConnections(ConfigParams connections)

  • connections: ConfigParams - configuration parameters to be read

RegisterAsync

Registers connection parameters into the discovery service.

public Task<void> RegisterAsync(string correlationId, string key, ConnectionParams connection)

  • correlationId: string - (optional) transaction id used to trace execution through the call chain.
  • key: string - key to uniquely identify the connection parameters.
  • connection: ConnectionParams - connection to be registered.

ResolveAllAsync

Resolves all connection parameters by their key.

public Task<List<ConnectionParams>> ResolveAllAsync(string correlationId, string key)

  • correlationId: string - (optional) transaction id used to trace execution through the call chain.
  • key: string - key to uniquely identify the connections.
  • returns: Task<List<ConnectionParams>> - list with resolved connections.

ResolveOneAsync

Resolves a single connection parameters by its key.

public Task<ConnectionParams> ResolveOneAsync(string correlationId, string key)

  • correlationId: string - (optional) transaction id used to trace execution through the call chain.
  • key: string - key to uniquely identify the connection.
  • returns: Task<ConnectionParams> - resolved connection.

Examples

ConfigParams config = ConfigParams.FromTuples(
    "key1.host", "10.1.1.100",
    "key1.port", "8080",
    "key2.host", "10.1.1.101",
    "key2.port", "8082"
);

MemoryDiscovery discovery = new MemoryDiscovery();

discovery.Configure(config);

await discovery.resolveOne("123", "key1");
// Result: host=10.1.1.100;port=8080
