Method Detail

getNodeId

@NotNull
@NotNull String getNodeId()

Returns the globally unique Identifier for this cluster node.

Returns:

the globally unique Identifier for this cluster node.

writeHeartBeat

void writeHeartBeat(long time)

Writes a heartbeat for this node at the given time. Caller will pass the time to stamp; in production this would normally be System.currentTimeMillis().

Parameters:

time - the time in millis to write as the heartbeat.

getLastHeartbeatTime

@Nullable
Long getLastHeartbeatTime(@NotNull
                          @NotNull String nodeId)

Returns the last time a heartbeat was sent by the given node.

A null value indicates no heartbeats have been sent by this node.

Parameters:

nodeId - the node

Returns:

the last time a heartbeat was sent by the given node.

findNodesWithHeartbeatsAfter

@NotNull
@NotNull Collection<String> findNodesWithHeartbeatsAfter(long time)

findNodesInfoWithHeartbeatsAfter

@NotNull
@NotNull List<BambooNodeInfo> findNodesInfoWithHeartbeatsAfter(long time)

Get all nodes in the database together with their heartbeats in the time window specified by the time argument.

Parameters:

time - the time in millis specifying the time window for the query

Returns:

list of nodes

Since:

9.4.0

findAll

@Deprecated
List<BambooNodeStatus> findAll()

Deprecated.

since 9.4.0 use findAllNodesInfo()

Get all heartbeats. The information about nodes' primary and alive attributes is not accurate.

findAllNodesInfo

@NotNull
@NotNull List<BambooNodeInfo> findAllNodesInfo()

Get all present in the database nodes together with their heartbeats.

Returns:

list of nodes

Since:

9.4.0

deleteNode

void deleteNode(@NotNull
                @NotNull String nodeId)

Remove node by the given id.

Since:

9.4.0

ensureNodeHeartbeatTableExists

void ensureNodeHeartbeatTableExists()

Creates heartbeat table if required.
