Field Description
topicSpec object

Required. Configuration of the topic to create.
topicSpec.
name		 string

Name of the topic.
topicSpec.

topicSpec includes only one of the fields topicConfig_2_1, topicConfig_2_6

A topic settings for 2.1.
topicSpec.
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.
topicSpec.
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).

deleteRetentionMs		 integer (int64)

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

The time to wait before deleting a file from the filesystem.
topicSpec.
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.

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.
topicSpec.
topicConfig_2_1.
minCompactionLagMs		 integer (int64)

The minimum time in milliseconds a message will remain uncompacted in the log.
topicSpec.
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.
topicSpec.
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.
topicSpec.
topicConfig_2_1.
preallocate		 boolean (boolean)

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

ID of the user or service account who initiated the operation.
modifiedAt string (date-time)

The time when the Operation resource was last modified.

String in RFC3339 text format.
done boolean (boolean)

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 object

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

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

An error message.
error.

A list of messages that carry the error details.
response object

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.
