IEchoRemoteNode Interface

The IEchoRemoteNode interface represents a remote node. More specifically, it actually represents the link between the local node and a remote node, since the IEchoRemoteNode interface is always retrieved from an existing local node context.

From the main TEcho class, you can retrieved the IEchoRemoteNode interface using the method GetRemoteNode. This method has two overloaded signatures, each one representing one of the two different ways of communication between nodes.

1. Rest/Json Server

In this case communication with the remote node will happen through a Rest/Json Echo server. To get the interface, pass the URL of the Echo server:

var
  RemoteNode: IEchoRemoteNode;
{...}
  RemoteNode := Echo.GetRemoteNode('http://serverhost/tms/echo/servernode');

2. Direct database connection

In this case the server database will be accessed directly. To get the interface, pass an IDBConnectionPool interface that connects with the remote database:

var
  ServerDatabasePool: IDBConnectionPool;
{...}
  RemoteNode := Echo.GetRemoteNode(ServerDatabasePool);

Methods

Name	Description
procedure Push;	Pushes all pending batches from the local node to the remote node.
procedure Pull;	Pulls all pending batches from remote node to local node.
procedure RegisterNode;	Registers the bidirectional replication link between local node and remote node
