Enum DefaultWriteType

java.lang.Object

java.lang.Enum<DefaultWriteType>

com.datastax.oss.driver.api.core.servererrors.DefaultWriteType

All Implemented Interfaces:

WriteType, Serializable, Comparable<DefaultWriteType>

public enum DefaultWriteType
extends Enum<DefaultWriteType>
implements WriteType

A default write type supported by the driver out of the box.

Enum Constant Summary

Enum Constants

Enum Constant and Description
BATCH A write to a multiple partition key that used the distributed batch log to ensure atomicity (atomicity meaning that if any statement in the batch succeeds, all will eventually succeed).
BATCH_LOG The initial write to the distributed batch log that Cassandra performs internally before a BATCH write.
CAS A conditional write.
CDC Indicates that the timeout was related to acquiring space for change data capture logs for cdc tracked tables.
COUNTER A counter write (that can be for one or multiple partition key).
SIMPLE A write to a single partition key.
UNLOGGED_BATCH A write to a multiple partition key that doesn't use the distributed batch log.
VIEW Indicates that the timeout was related to acquiring locks needed for updating materialized views affected by write operation.

Enum Constant Detail

SIMPLE

public static final DefaultWriteType SIMPLE

A write to a single partition key. Such writes are guaranteed to be atomic and isolated.

BATCH

public static final DefaultWriteType BATCH

A write to a multiple partition key that used the distributed batch log to ensure atomicity (atomicity meaning that if any statement in the batch succeeds, all will eventually succeed).

UNLOGGED_BATCH

public static final DefaultWriteType UNLOGGED_BATCH

A write to a multiple partition key that doesn't use the distributed batch log. Atomicity for such writes is not guaranteed

COUNTER

public static final DefaultWriteType COUNTER

A counter write (that can be for one or multiple partition key). Such write should not be replayed to avoid over-counting.

BATCH_LOG

public static final DefaultWriteType BATCH_LOG

The initial write to the distributed batch log that Cassandra performs internally before a BATCH write.

CAS

public static final DefaultWriteType CAS

A conditional write. If a timeout has this WriteType, the timeout has happened while doing the compare-and-swap for an conditional update. In this case, the update may or may not have been applied.

VIEW

public static final DefaultWriteType VIEW

Indicates that the timeout was related to acquiring locks needed for updating materialized views affected by write operation.

CDC

public static final DefaultWriteType CDC

Indicates that the timeout was related to acquiring space for change data capture logs for cdc tracked tables.

Method Detail

values

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

Returns:

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

valueOf

public static DefaultWriteType 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
