CreateTopicRequest​

clusterId : string​

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

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

topicSpec : TopicSpec​

Configuration of the topic to create.

TopicSpec​

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.

One of topicConfig​

User-defined settings for the topic.

  • topicConfig_2_8 : TopicConfig2_8​
  • topicConfig_3 : TopicConfig3​

TopicConfig2_8​

A topic settings for 2.8

CleanupPolicy​
  • 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.log_retention_ms][2] 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.

cleanupPolicy : CleanupPolicy​

Retention policy to use on old log messages.

compressionType : CompressionType​

The compression type for a given topic.

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.log_flush_interval_messages 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.log_flush_interval_ms 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 cleanup_policy 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.log_retention_bytes 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.log_retention_ms 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.log_segment_bytes 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.log_preallocate setting on the topic level.

TopicConfig3​

A topic settings for 3.x

CleanupPolicy​
  • CLEANUP_POLICY_UNSPECIFIED

  • CLEANUP_POLICY_DELETE

    This policy discards log segments when either their retention time or log size limit is reached. See also: [KafkaConfig3.log_retention_ms][10] 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.

cleanupPolicy : CleanupPolicy​

Retention policy to use on old log messages.

compressionType : CompressionType​

The compression type for a given topic.

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 KafkaConfig3.log_flush_interval_messages 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 KafkaConfig3.log_flush_interval_ms 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 cleanup_policy 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 KafkaConfig3.log_retention_bytes 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 KafkaConfig3.log_retention_ms 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 KafkaConfig3.log_segment_bytes 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 KafkaConfig3.log_preallocate setting on the topic level.

Operation​

An Operation resource. For more information, see Operation.

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 : google.protobuf.Any​

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.

One of result​

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.

  • error : google.rpc.Status​

    The error result of the operation in case of failure or cancellation.

  • response : google.protobuf.Any​
    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.
