Method list

Retrieves the list of Kafka topics in the specified cluster.

HTTP request

GET https://mdb.api.cloud.yandex.net/managed-kafka/v1/clusters/{clusterId}/topics

Path parameters

Parameter Description
clusterId Required. ID of the Apache Kafka® cluster to list topics in. To get the cluster ID, make a list request. The maximum string length in characters is 50.

Query parameters

Parameter Description
pageSize The maximum number of results per page to return. If the number of available results is larger than pageSize, the service returns a nextPageToken that can be used to get the next page of results in subsequent list requests. The maximum value is 1000.
pageToken Page token. To get the next page of results, set pageToken to the nextPageToken returned by a previous list request. The maximum string length in characters is 100.

Response

HTTP Code: 200 - OK

Field Description
topics[] object

An Kafka topic. For more information, see the Concepts -> Topics and partitions section of the documentation.
topics[].
name		 string

Name of the topic.
topics[].
clusterId		 string

ID of an Apache Kafka® cluster that the topic belongs to.

To get the Apache Kafka® cluster ID, make a list request.
topics[].
partitions		 integer (int64)

The number of the topic's partitions.
topics[].
replicationFactor		 integer (int64)

Amount of data copies (replicas) for the topic in the cluster.
topics[].
topicConfig_2_1		 object
topics[] includes only one of the fields topicConfig_2_1, topicConfig_2_6

A topic settings for 2.1.
topics[].
topicConfig_2_1.
cleanupPolicy		 string

Retention policy to use on old log messages.

  • CLEANUP_POLICY_DELETE: this policy discards log segments when either their retention time or log size limit is reached. See also: logRetentionMs and other similar parameters.
  • CLEANUP_POLICY_COMPACT: this policy compacts messages in log.
  • CLEANUP_POLICY_COMPACT_AND_DELETE: this policy use both compaction and deletion for messages and log segments.
topics[].
topicConfig_2_1.
compressionType		 string

The compression type for a given topic.

  • COMPRESSION_TYPE_UNCOMPRESSED: no codec (uncompressed).
  • COMPRESSION_TYPE_ZSTD: Zstandard codec.
  • COMPRESSION_TYPE_LZ4: LZ4 codec.
  • COMPRESSION_TYPE_SNAPPY: Snappy codec.
  • COMPRESSION_TYPE_GZIP: GZip codec.
  • COMPRESSION_TYPE_PRODUCER: the codec to use is set by a producer (can be any of ZSTD, LZ4, GZIP or SNAPPY codecs).
topics[].
topicConfig_2_1.
deleteRetentionMs		 integer (int64)

The amount of time in milliseconds to retain delete tombstone markers for log compacted topics.
topics[].
topicConfig_2_1.
fileDeleteDelayMs		 integer (int64)

The time to wait before deleting a file from the filesystem.
topics[].
topicConfig_2_1.
flushMessages		 integer (int64)

The number of messages accumulated on a log partition before messages are flushed to disk.

This setting overrides the cluster-level logFlushIntervalMessages setting on the topic level.
topics[].
topicConfig_2_1.
flushMs		 integer (int64)

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 logFlushIntervalMs setting on the topic level.
topics[].
topicConfig_2_1.
minCompactionLagMs		 integer (int64)

The minimum time in milliseconds a message will remain uncompacted in the log.
topics[].
topicConfig_2_1.
retentionBytes		 integer (int64)

The maximum size a partition can grow to before Kafka will discard old log segments to free up space if the delete cleanupPolicy is in effect. It is helpful if you need to control the size of log due to limited disk space.

This setting overrides the cluster-level logRetentionBytes setting on the topic level.
topics[].
topicConfig_2_1.
retentionMs		 integer (int64)

The number of milliseconds to keep a log segment's file before deleting it.

This setting overrides the cluster-level logRetentionMs setting on the topic level.
topics[].
topicConfig_2_1.
maxMessageBytes		 integer (int64)

The largest record batch size allowed in topic.
topics[].
topicConfig_2_1.
minInsyncReplicas		 integer (int64)

This configuration specifies the minimum number of replicas that must acknowledge a write to topic for the write to be considered successful (when a producer sets acks to "all").
topics[].
topicConfig_2_1.
segmentBytes		 integer (int64)

This configuration controls the segment file size for the log. Retention and cleaning is always done a file at a time so a larger segment size means fewer files but less granular control over retention.

This setting overrides the cluster-level logSegmentBytes setting on the topic level.
topics[].
topicConfig_2_1.
preallocate		 boolean (boolean)

True if we should preallocate the file on disk when creating a new log segment.

This setting overrides the cluster-level logPreallocate setting on the topic level.
topics[].

topics[] includes only one of the fields topicConfig_2_1, topicConfig_2_6

A topic settings for 2.6
topics[].
