@IgniteSpiMultipleInstancesSupport(value=true) @DiscoverySpiOrderSupport(value=true) @DiscoverySpiHistorySupport(value=true) @DiscoverySpiMutableCustomMessageSupport(value=true) public class TcpDiscoverySpi extends IgniteSpiAdapter implements org.apache.ignite.internal.managers.discovery.IgniteDiscoverySpi
Nodes are organized in ring. So almost all network exchange (except few cases) is done across it.
If node is configured as client node (see IgniteConfiguration.clientMode
)
TcpDiscoverySpi starts in client mode as well. In this case node does not take its place in the ring,
but it connects to random node in the ring (IP taken from IP finder configured) and
use it as a router for discovery traffic.
Therefore slow client node or its shutdown will not affect whole cluster. If TcpDiscoverySpi
needs to be started in server mode regardless of IgniteConfiguration.clientMode
,
forceSrvMode
should be set to true.
At startup SPI tries to send messages to random IP taken from
TcpDiscoveryIpFinder
about self start (stops when send succeeds)
and then this info goes to coordinator. When coordinator processes join request
and issues node added messages and all other nodes then receive info about new node.
IgniteConfiguration.getFailureDetectionTimeout()
) for details) are chosen to make possible for discovery
SPI work reliably on most of hardware and virtual deployments, but this has made failure detection time worse.
If it's needed to tune failure detection then it's highly recommended to do this using
IgniteConfiguration.setFailureDetectionTimeout(long)
. This failure timeout automatically controls the
following parameters: getSocketTimeout()
, getAckTimeout()
, getMaxAckTimeout()
,
getReconnectCount()
. If any of those parameters is set explicitly, then the failure timeout setting will be
ignored. As an example, for stable low-latency networks the failure detection timeout may be set to ~120 ms.
If it's required to perform advanced settings of failure detection and
IgniteConfiguration.getFailureDetectionTimeout()
is unsuitable then various TcpDiscoverySpi
configuration parameters may be used. As an example, for stable low-latency networks the following more aggressive
settings are recommended (which allows failure detection time ~200ms):
setSocketTimeout(long)
) - 200mssetAckTimeout(long)
) - 50mssetIpFinder(TcpDiscoveryIpFinder)
).
See the following IP finder implementations for details on configuration:

)setLocalPort(int)
)setLocalPortRange(int)
)setReconnectCount(int)
)setNetworkTimeout(long)
)setSocketTimeout(long)
)setAckTimeout(long)

If acknowledgement is not received within this timeout, sending is considered as failed and SPI tries to repeat message sending.

for details.public void setConnectionRecoveryTimeout(long connRecoveryTimeout)
In case local node has temporary connectivity issues with part of the cluster, it may sequentially fail nodes one-by-one till successfully connect to one that has a fine connection with. This leads to fail of big number of nodes.
To overcome that issue, local node will do a sequential connection tries to next nodes. But if new next node has connection to previous it forces local node to retry connect to previous. These tries will last till timeout will not finished. When timeout is over, but no success in connecting to nodes it will segment itself.
Cannot be greater than IgniteSpiAdapter.failureDetectionTimeout()

Default is DFLT_CONNECTION_RECOVERY_TIMEOUT
.
