java.lang.Object
- java.lang.Enum<MirrorTopicError>
- - org.apache.kafka.common.MirrorTopicError

All Implemented Interfaces:
Serializable, Comparable<MirrorTopicError>
```
public enum MirrorTopicError
extends Enum<MirrorTopicError>
```
Reason for persistent failure of a mirror topic.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`ILLEGAL_STATE` Illegal state encountered while processing mirror topic.
`NO_ERROR` The mirror topic is not in a persistent failed state.
`NON_MONOTONIC_LOG_APPEND_EPOCH` Records received from source leader with epoch lower than previous epoch in the log.
`NON_MONOTONIC_SOURCE_EPOCH` Source leader epoch went backwards, source topic may have been recreated.
`NOT_SET` No reason was provided by the broker because the broker was running an older version.
`RECORD_TOO_LARGE` Records received from source leader that are larger than the maximum configured for the cluster link.
`SOURCE_PARTITIONS_DECREASED` Source partition count reduced, source topic may have been recreated.
`SOURCE_TOPIC_ID_CHANGED` Source topic id is different from the persisted source topic id.
`SOURCE_TOPIC_MAY_BE_DELETED` Source topic was not in the metadata response or metadata response contained a partition epoch that is lower than last seen epoch.
`UNEXPECTED_TRUNCATION` Truncation below high watermark with inconsistent epoch offsets.
`UNKNOWN` The error code couldn't be mapped because a new error code was set by a broker with a later version.
`UNSUPPORTED_MESSAGE_FORMAT` Records with message format v0 or v1 cannot be replicated using cluster linking since we cannot reliably detect log divergence with these older message formats.
`UNSUPPORTED_MIRROR_STATE` Newer mirror topic state not supported by a broker still running on older version.

- Enum Constant Detail
  - UNKNOWN
```
public static final MirrorTopicError UNKNOWN
```
    The error code couldn't be mapped because a new error code was set by a broker with a later version.
  - NOT_SET
```
public static final MirrorTopicError NOT_SET
```
    No reason was provided by the broker because the broker was running an older version. Default reason will be used by the client.
  - NO_ERROR
```
public static final MirrorTopicError NO_ERROR
```
    The mirror topic is not in a persistent failed state.
  - SOURCE_TOPIC_MAY_BE_DELETED
```
public static final MirrorTopicError SOURCE_TOPIC_MAY_BE_DELETED
```
    Source topic was not in the metadata response or metadata response contained a partition epoch that is lower than last seen epoch. Topic may have been deleted or cluster link no longer has authorization to describe topic. This is used as the default reason when reason was not set by older brokers.
  - SOURCE_TOPIC_ID_CHANGED
```
public static final MirrorTopicError SOURCE_TOPIC_ID_CHANGED
```
    Source topic id is different from the persisted source topic id. Source topic was recreated.
  - SOURCE_PARTITIONS_DECREASED
```
public static final MirrorTopicError SOURCE_PARTITIONS_DECREASED
```
    Source partition count reduced, source topic may have been recreated.
  - NON_MONOTONIC_LOG_APPEND_EPOCH
```
public static final MirrorTopicError NON_MONOTONIC_LOG_APPEND_EPOCH
```
    Records received from source leader with epoch lower than previous epoch in the log. This indicates source topic recreation or corrupted source logs.
  - UNEXPECTED_TRUNCATION
```
public static final MirrorTopicError UNEXPECTED_TRUNCATION
```
    Truncation below high watermark with inconsistent epoch offsets. This indicates source topic recreation or corrupted source logs.
  - UNSUPPORTED_MESSAGE_FORMAT
```
public static final MirrorTopicError UNSUPPORTED_MESSAGE_FORMAT
```
    Records with message format v0 or v1 cannot be replicated using cluster linking since we cannot reliably detect log divergence with these older message formats.
  - NON_MONOTONIC_SOURCE_EPOCH
```
public static final MirrorTopicError NON_MONOTONIC_SOURCE_EPOCH
```
    Source leader epoch went backwards, source topic may have been recreated.
  - ILLEGAL_STATE
```
public static final MirrorTopicError ILLEGAL_STATE
```
    Illegal state encountered while processing mirror topic. This is unexpected and indicates a bug in the implementation.
  - UNSUPPORTED_MIRROR_STATE
```
public static final MirrorTopicError UNSUPPORTED_MIRROR_STATE
```
    Newer mirror topic state not supported by a broker still running on older version. This will resolve itself when brokers are upgraded to the newer version that supports the new state.
  - RECORD_TOO_LARGE
```
public static final MirrorTopicError RECORD_TOO_LARGE
```
    Records received from source leader that are larger than the maximum configured for the cluster link.
- Method Detail
  - values
```
public static MirrorTopicError[] 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 (MirrorTopicError c : MirrorTopicError.values())
    System.out.println(c);
```
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static MirrorTopicError 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

  - errorOrDefault

public static MirrorTopicError errorOrDefault(MirrorTopicError error,
                                              boolean failed)
