Class MultiPrimaryReplicaClient

java.lang.Object

com.singlestore.jdbc.client.impl.MultiPrimaryClient

com.singlestore.jdbc.client.impl.MultiPrimaryReplicaClient

All Implemented Interfaces:

com.singlestore.jdbc.client.Client, AutoCloseable

public class MultiPrimaryReplicaClient
extends MultiPrimaryClient

Handling connection failing automatic reconnection transparently when possible for replication Topology.

remark: would have been better using proxy, but for AOT compilation, avoiding to using not supported proxy class.

MultiPrimaryReplicaClient

public MultiPrimaryReplicaClient(Configuration conf,
                                 ReentrantLock lock)
                          throws SQLException

Throws:

SQLException

Method Detail

reConnect

protected void reConnect()
                  throws SQLException

Reconnect connection, trying to continue transparently if possible. Different cases. * replica fails => reconnect to replica or to master if no replica available

if reconnect succeed on replica / use master, no problem, continuing without interruption // if reconnect primary, then replay transaction / throw exception if was in transaction.

Overrides:

reConnect in class MultiPrimaryClient

Throws:

SQLException - if exception
