This command modifies a topic.

Usage

topic modify --database-name NAME
             --name NAME
             [--new-name NEW_NAME]
             [--retention-ms MILLISECONDS]
             [--message-timestamp-type CreateTime|LogAppendTime] 
             [--message-timestamp-before-max-ms MILLISECONDS]
             [--message-timestamp-after-max-ms MILLISECONDS]

Required Parameters

`--database-name NAME`	The name of the database where the topic resides.
`--name NAME`	The name of the topic to be modified.

Options

`--new-name NEW_NAME`	This option lets you rename an existing topic.
`--retention-ms MILLISECONDS`	The amount of time, in milliseconds, to keep an event record in the topic. When the retention period for a record expires, the records is deleted from the topic.
`--message-timestamp-type CreateTime\|LogAppendTime`	Determines how the event timestamp is set: `CreateTime` (default): The timestamp is based on the time when the event was encountered at the event producer. `LogAppendTime`: The timestamp is based on the time when the event record was added to the log at the event broker.
`--message-timestamp-before-max-ms MILLISECONDS`	If the message timestamp type is set to `CreateTime`, specify this option to determine how much earlier the message timestamp can be than the broker timestamp. If this value is exceeded, the message is rejected.
`--message-timestamp-after-max-ms MILLISECONDS`	If the message timestamp type is set to `CreateTime`, specify this option to determine how much later the message timestamp can be than the broker timestamp. If this value is exceeded, the message is rejected.

Example

To set the message timestamp type to LogAppendTime:

vcli: admin> topic modify --database-name kafkatopics --name mytopic --message-timestamp-type LogAppendTime

topic delete
