.SH "REQUIRED FLAGS"

.RS 2m
.TP 2m

At least one of these must be specified:


.RS 2m
.TP 2m
\fB\-\-partitions\fR=\fIPARTITIONS\fR

The number of partitions in a topic. You can increase the partition count for a
topic, but you cannot decrease it. Increasing partitions for a topic that uses a
key might change how messages are distributed.

.TP 2m

At most one of these can be specified:


.RS 2m
.TP 2m
\fB\-\-clear\-configs\fR

Remove all the configurations for the topic.

.TP 2m
\fB\-\-configs\fR=[\fIKEY\fR=\fIVALUE\fR,...]

Configuration for the topic that are overridden from the cluster defaults. The
key of the map is a Kafka topic property name, for example:
\f5cleanup.policy=compact\fR,\f5compression.type=producer\fR. If you provide a
map with a key that already exists, only that configuration is updated. If the
map contains a key that does not exist, the entry is appended to the topic
configuration.
