Description copied from interface: ConnectionPool

This is used to create a ClientConnection on an existing Connection pool. The Connection pool implementation decides if a new connection needs to be established to the PravegaNode or an existing connection can be reused to establish the connection.

Specified by:

getClientConnection in interface ConnectionPool

Parameters:

flow - Flow

location - The Pravega Node Uri.

rp - ReplyProcessor instance.

Returns:

An instance of client connection.

getClientConnection

public java.util.concurrent.CompletableFuture<ClientConnection> getClientConnection(io.pravega.shared.protocol.netty.PravegaNodeUri location,
                                                                                    io.pravega.shared.protocol.netty.ReplyProcessor rp)

Description copied from interface: ConnectionPool

This is used to create a ClientConnection where flows are disabled. This implies that only one ClientConnection can exist on the underlying connection.

Specified by:

getClientConnection in interface ConnectionPool

Parameters:

location - The Pravega Node Uri.

rp - ReplyProcessor instance.

Returns:

An instance of client connection.

pruneUnusedConnections

public void pruneUnusedConnections()

Used only for testing.

getActiveChannels

public java.util.List<io.pravega.client.connection.impl.ConnectionPoolImpl.Connection> getActiveChannels()

close

public void close()

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface ConnectionPool

getInternalExecutor

public java.util.concurrent.ScheduledExecutorService getInternalExecutor()

Description copied from interface: ConnectionPool

Returns the client internal thread pool executor.

Specified by:

getInternalExecutor in interface ConnectionPool
