ConsumerProperties
Create properties for a container that will subscribe to the specified topics.- Parameters:
topics- the topics.
-
ConsumerProperties
Create properties for a container that will subscribe to topics matching the specified pattern. The framework will create a container that subscribes to all topics matching the specified pattern to get dynamically assigned partitions. The pattern matching will be performed periodically against topics existing at the time of check.- Parameters:
topicPattern- the pattern.- See Also:
-
CommonClientConfigs.METADATA_MAX_AGE_CONFIG
-
ConsumerProperties
Create properties for a container that will assign itself the provided topic partitions.- Parameters:
topicPartitions- the topic partitions.
-

Set the group id for this container. Overrides anygroup.idproperty provided by the consumer factory configuration.- Parameters:
groupId- the group id.
-
getGroupId
Return the container's group id.- Returns:
- the group id.
-
getClientId
Return the client id.- Returns:
- the client id.
- See Also:

setSyncCommitTimeout
Set the timeout for commitSync operations (ifisSyncCommits(). Overrides the default api timeout property.- Parameters:
syncCommitTimeout- the timeout.- See Also:
-
getSyncCommitTimeout
Return the sync commit timeout.- Returns:
- the timeout.
-
setCommitCallback
public void setCommitCallback(org.apache.kafka.clients.consumer.OffsetCommitCallback commitCallback) Set the commit callback; by default a simple logging callback is used to log success at DEBUG level and failures at ERROR level. Used whensyncCommitsis false.- Parameters:
commitCallback- the callback.- See Also:
-
setOffsetAndMetadataProvider
Set the offset and metadata provider associated to a commit callback.- Parameters:
offsetAndMetadataProvider- an offset and metadata provider.- Since:
- 2.8.5
- See Also:
-
getCommitCallback
Return the commit callback.- Returns:
- the callback.
-
getOffsetAndMetadataProvider
Return the offset and metadata provider.- Returns:
- the offset and metadata provider.
-
setSyncCommits
public void setSyncCommits(boolean syncCommits) Set whether or not to call consumer.commitSync() or commitAsync() when the container is responsible for commits. Default true.- Parameters:
syncCommits- true to use commitSync().- See Also:
-
isSyncCommits
public boolean isSyncCommits() -
getCommitLogLevel
The level at which to log offset commits.- Returns:
- the level.
-
setCommitLogLevel
Set the level at which to log offset commits. Default: DEBUG.- Parameters:
commitLogLevel- the level.
-
getKafkaConsumerProperties
Get the consumer properties that will be merged with the consumer properties provided by the consumer factory; properties here will supersede any with the same name(s) in the consumer factory. You can add non-String-valued properties, but the property name (hashtable key) must be String; all others will be ignored.group.idandclient.idare ignored.- Returns:
- the properties.
- See Also:

- the interval.
-
setAuthExceptionRetryInterval
Set the interval between retries after andAuthenticationExceptionororg.apache.kafka.common.errors.AuthorizationExceptionis thrown byKafkaConsumer. By default the field is null and retries are disabled. In such case the container will be stopped. The interval must be less thanmax.poll.interval.msconsumer property.- Parameters:
authExceptionRetryInterval- the duration between retries- Since:
- 2.8
-
getCommitRetries
public int getCommitRetries()The number of retries allowed when aRetriableCommitFailedExceptionis thrown by the consumer when usingsetSyncCommits(boolean)set to true.- Returns:

-
setCommitRetries
public void setCommitRetries(int commitRetries) Set number of retries allowed when aRetriableCommitFailedExceptionis thrown by the consumer when usingsetSyncCommits(boolean)set to true. Default 3 (4 attempts total).- Parameters:
commitRetries- the commitRetries.- Since:
- 2.3.9
- See Also:
-
isFixTxOffsets
public boolean isFixTxOffsets()Whether or not to correct terminal transactional offsets.- Returns:
- true to fix.
- Since:
- 2.5.6
- See Also:
-
setFixTxOffsets
public void setFixTxOffsets(boolean fixTxOffsets) When consuming records produced by a transactional producer, and the consumer is positioned at the end of a partition, the lag can incorrectly be reported as greater than zero, due to the pseudo record used to indicate transaction commit/rollback and, possibly, the presence of rolled-back records. This does not functionally affect the consumer but some users have expressed concern that the "lag" is non-zero. Set this to true and the container will correct such mis-reported offsets. The check is performed before the next poll to avoid adding significant complexity to the commit processing. IMPORTANT: At the time of writing, the lag will only be corrected if the consumer is configured withisolation.level=read_committedandmax.poll.recordsis greater than 1. See https://issues.apache.org/jira/browse/KAFKA-10683 for more information.- Parameters:
fixTxOffsets- true to correct the offset(s).- Since:
- 2.5.6
-

- true to check.
- Since:
- 2.8.1
-
setCheckDeserExWhenKeyNull
public void setCheckDeserExWhenKeyNull(boolean checkDeserExWhenKeyNull) Set to true to always check forDeserializationExceptionheader when a null key is received. Useful when the consumer code cannot determine that anErrorHandlingDeserializerhas been configured, such as when using a delegating deserializer.- Parameters:
checkDeserExWhenKeyNull- true to always check.- Since:
- 2.8.1
-
isCheckDeserExWhenValueNull
public boolean isCheckDeserExWhenValueNull()Always check for a deserialization exception header with a null value.- Returns:
- true to check.
- Since:
- 2.8.1
-
setCheckDeserExWhenValueNull
public void setCheckDeserExWhenValueNull(boolean checkDeserExWhenValueNull) Set to true to always check forDeserializationExceptionheader when a null value is received.
