Field

Description

clusterId

string

Required field. ID of the Apache Kafka® cluster to create a topic in.

To get the cluster ID, make a ClusterService.List request.

topicSpec

TopicSpec

Required field. Configuration of the topic to create.

TopicSpec

Field	Description
name	string Name of the topic.
partitions	google.protobuf.Int64Value The number of the topic's partitions.
replicationFactor	google.protobuf.Int64Value Amount of copies of a topic data kept in the cluster.
topicConfig_2_8	TopicConfig2_8 Includes only one of the fields `topicConfig_2_8`, `topicConfig_3`. User-defined settings for the topic.
topicConfig_3	TopicConfig3 Includes only one of the fields `topicConfig_2_8`, `topicConfig_3`. 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. `CLEANUP_POLICY_UNSPECIFIED` `CLEANUP_POLICY_DELETE`: This policy discards log segments when either their retention time or log size limit is reached. See also: KafkaConfig2_8.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.
compressionType	enum CompressionType The compression type for a given topic. `COMPRESSION_TYPE_UNSPECIFIED` `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).
deleteRetentionMs	google.protobuf.Int64Value The amount of time in milliseconds to retain delete tombstone markers for log compacted topics.
fileDeleteDelayMs	google.protobuf.Int64Value The time to wait before deleting a file from the filesystem.
flushMessages	google.protobuf.Int64Value 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	google.protobuf.Int64Value 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	google.protobuf.Int64Value The minimum time in milliseconds a message will remain uncompacted in the log.
retentionBytes	google.protobuf.Int64Value 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 KafkaConfig2_8.logRetentionBytes setting on the topic level.
retentionMs	google.protobuf.Int64Value 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	google.protobuf.Int64Value The largest record batch size allowed in topic.
minInsyncReplicas	google.protobuf.Int64Value 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").
segmentBytes	google.protobuf.Int64Value 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 KafkaConfig2_8.logSegmentBytes setting on the topic level.
preallocate	google.protobuf.BoolValue 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.

An Operation resource. For more information, see Operation.

Field	Description
id	string ID of the operation.
description	string Description of the operation. 0-256 characters long.
createdAt	google.protobuf.Timestamp Creation timestamp.
createdBy	string ID of the user or service account who initiated the operation.
modifiedAt	google.protobuf.Timestamp The time when the Operation resource was last modified.
done	bool If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
metadata	CreateTopicMetadata Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
error	google.rpc.Status The error result of the operation in case of failure or cancellation. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
response	Topic The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is the standard Create/Update, the response should be the target resource of the operation. Any method that returns a long-running operation should document the response type, if any. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
