All Implemented Interfaces:

Serializable, Comparable<WriteMode>

public enum WriteMode
extends Enum<WriteMode>

Enum representing the write mode for table write sessions.

BATCH mode: Default mode. Data is written to the table and becomes visible only after the session is committed.

STREAMING mode: Data becomes visible immediately after flush, without requiring explicit commit. The session uses a default session ID and does not require explicit session creation.

Streaming write mode. Data becomes visible immediately after flush. No explicit session creation required, uses default session ID.

Method Detail

values

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

Returns:

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

valueOf

public static WriteMode 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

getValue

public String getValue()

fromValue

public static WriteMode fromValue(String value)
