Method Detail

values

public static Layout.ReplicationMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Layout.ReplicationMode c : Layout.ReplicationMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Layout.ReplicationMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

validateSegmentSeal

public abstract void validateSegmentSeal(Layout.LayoutSegment layoutSegment,
                                         Map<String,CompletableFuture<Boolean>> completableFutureMap)
                                  throws QuorumUnreachableException

Seals the layout segment.

Throws:

QuorumUnreachableException

getMinReplicationFactor

public abstract int getMinReplicationFactor(Layout layout,
                                            Layout.LayoutStripe stripe)

Compute the min replication factor for the log unit servers in the replication protocol for a specific stripe.

Parameters:

layout - the layout to compute the min replication factor for.

stripe - The stripe for which the minimum replication factor is needed.

Returns:

the minimum amount of nodes required to maintain replication

getStreamView

public abstract IStreamView getStreamView(CorfuRuntime r,
                                          UUID streamId,
                                          StreamOptions options)

getUnsafeStreamView

public abstract IStreamView getUnsafeStreamView(CorfuRuntime r,
                                                UUID streamId,
                                                StreamOptions options)

getReplicationProtocol

public IReplicationProtocol getReplicationProtocol(CorfuRuntime r)

getClusterHealthForSegment

public abstract ClusterStatusReport.ClusterStatus getClusterHealthForSegment(Layout.LayoutSegment layoutSegment,
                                                                             Set<String> responsiveNodes)

Returns the health of the cluster for a given segment.

Parameters:

layoutSegment - Layout Segment

responsiveNodes - Set of all responsive nodes.

Returns:

Cluster Health.
