All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<StorageEngineFactory.StoreMode>

Enclosing interface:

StorageEngineFactory<K,V>

public static enum StorageEngineFactory.StoreMode
extends java.lang.Enum<StorageEngineFactory.StoreMode>

Enum to describe different modes a StorageEngine can be created in. The BulkLoad mode is used when bulk loading of data onto the store, e.g., store-restoration at Samza startup. In this mode, the underlying store will tailor itself for write-intensive ops -- tune its params, adapt its compaction behaviour, etc. The ReadWrite mode is used for normal read-write ops by the application.

Method Detail

values

public static StorageEngineFactory.StoreMode[] 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 (StorageEngineFactory.StoreMode c : StorageEngineFactory.StoreMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static StorageEngineFactory.StoreMode valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
