An Kafka topic.

Field |
Description |
name |
string Name of the topic. |
clusterId |
string ID of an Apache Kafka® cluster that the topic belongs to. To get the Apache Kafka® cluster ID, make a ClusterService.List request. |
partitions |
The number of the topic's partitions. |
replicationFactor |
Amount of data copies (replicas) for the topic in the cluster. |
topicConfig_2_8 |
Includes only one of the fields User-defined settings for the topic. |
topicConfig_3 |
Includes only one of the fields User-defined settings for the topic. |
TopicConfig2_8
A topic settings for 2.8
Field |
Description |
cleanupPolicy |
enum CleanupPolicy Retention policy to use on old log messages.
|
compressionType |
enum CompressionType The compression type for a given topic.
|
deleteRetentionMs |
The amount of time in milliseconds to retain delete tombstone markers for log compacted topics. |
fileDeleteDelayMs |
The time to wait before deleting a file from the filesystem. |
flushMessages |
The number of messages accumulated on a log partition before messages are flushed to disk. This setting overrides the cluster-level KafkaConfig2_8.logFlushIntervalMessages setting on the topic level. |
flushMs |
The maximum time in milliseconds that a message in the topic is kept in memory before flushed to disk. This setting overrides the cluster-level KafkaConfig2_8.logFlushIntervalMs setting on the topic level. |
minCompactionLagMs |
The minimum time in milliseconds a message will remain uncompacted in the log. |
retentionBytes |
The maximum size a partition can grow to before Kafka will discard old log segments to free up space if the This setting overrides the cluster-level KafkaConfig2_8.logRetentionBytes setting on the topic level. |
retentionMs |
The number of milliseconds to keep a log segment's file before deleting it. This setting overrides the cluster-level KafkaConfig2_8.logRetentionMs setting on the topic level. |
maxMessageBytes |
The largest record batch size allowed in topic. |
minInsyncReplicas |
This configuration specifies the minimum number of replicas that must acknowledge a write to topic for the write |
segmentBytes |
This configuration controls the segment file size for the log. Retention and cleaning is always done a file This setting overrides the cluster-level KafkaConfig2_8.logSegmentBytes setting on the topic level. |
preallocate |
True if we should preallocate the file on disk when creating a new log segment. This setting overrides the cluster-level KafkaConfig2_8.logPreallocate setting on the topic level. |
