Field

Description

updateMask

string (field-mask)

A comma-separated names off ALL fields to be updated.
Only the specified fields will be changed. The others will be left untouched.
If the field is specified in updateMask and no value for that field was sent in the request,
the field's value will be reset to the default. The default value for most fields is null or 0.

If updateMask is not sent in the request, all fields' values will be updated.
Fields specified in the request will be updated to provided values.
The rest of the fields will be reset to the default.

topicSpec

TopicSpec

New configuration of the topic.

Use updateMask to prevent reverting all topic settings that are not listed in topicSpec to their default values.

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.

deleteRetentionMs

string (int64)

The amount of time in milliseconds to retain delete tombstone markers for log compacted topics.

fileDeleteDelayMs

string (int64)

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