Enum Constant Summary

Enum Constants

Enum Constant and Description
ACTIVE The default state of a slice.
CONSTRUCTION When a shard is split, the new sub-shards are put in that state while the split operation is in progress.
INACTIVE A slice is put in that state after it has been successfully split.
RECOVERY Sub-shards of a split shard are put in that state, when they need to create replicas in order to meet the collection's replication factor.

Enum Constant Detail

ACTIVE

public static final Slice.State ACTIVE

The default state of a slice.

INACTIVE

public static final Slice.State INACTIVE

A slice is put in that state after it has been successfully split. See the reference guide for more details.

CONSTRUCTION

public static final Slice.State CONSTRUCTION

When a shard is split, the new sub-shards are put in that state while the split operation is in progress. A shard in that state still receives update requests from the parent shard leader, however does not participate in distributed search.

RECOVERY

public static final Slice.State RECOVERY

Sub-shards of a split shard are put in that state, when they need to create replicas in order to meet the collection's replication factor. A shard in that state still receives update requests from the parent shard leader, however does not participate in distributed search.

Method Detail

values

public static Slice.State[] 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 (Slice.State c : Slice.State.values())
    System.out.println(c);

Returns:

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

valueOf

public static Slice.State 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

toString

public String toString()

Overrides:

toString in class Enum<Slice.State>

getState

public static Slice.State getState(String stateStr)

Converts the state string to a State instance.
