Method Detail

getClientConnection

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

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.

Parameters:

flow - Flow

uri - The Pravega Node Uri.

rp - ReplyProcessor instance.

Returns:

An instance of client connection.

getClientConnection

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

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

Parameters:

uri - The Pravega Node Uri.

rp - ReplyProcessor instance.

Returns:

An instance of client connection.

close

void close()

Specified by:

close in interface java.lang.AutoCloseable

getInternalExecutor

java.util.concurrent.ScheduledExecutorService getInternalExecutor()

Returns the client internal thread pool executor.
