.IP "\(em" 2m
provide the argument \f5topic\fR on the command line with a fully specified
name;
.IP "\(em" 2m
provide the argument \f5\-\-project\fR on the command line;
.IP "\(em" 2m
set the property \f5core/project\fR.

.SH "REQUIRED FLAGS"

.RS 2m
.TP 2m

At least one of these must be specified:


.RS 2m
.TP 2m
\fB\-\-message\-retention\-period\fR=\fIMESSAGE_RETENTION_PERIOD\fR

How long a published message is retained. If unset, messages will only be
dropped to make space for new ones once the \f5per\-partition\-bytes\fR limit is
reached. A valid example value of this flag would be
\f5message\-retention\-period="2w"\fR.

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

Number of partitions in the topic.

.TP 2m
\fB\-\-per\-partition\-bytes\fR=\fIPER_PARTITION_BYTES\fR

Provisioned storage, in bytes, per partition. If the number of bytes stored in
any of the topic's partitions exceeds this value, older messages will be dropped
to make room for newer ones, regardless of the value of
\f5message\-retention\-period\fR. A valid example value of this flag would be
\f5per\-partition\-bytes=30GiB\fR.

.TP 2m
\fB\-\-per\-partition\-publish\-mib\fR=\fIPER_PARTITION_PUBLISH_MIB\fR

Topic partition publish throughput capacity in MiB/s. Must be between 4 and 16.

.TP 2m
\fB\-\-per\-partition\-subscribe\-mib\fR=\fIPER_PARTITION_SUBSCRIBE_MIB\fR

Topic partition subscribe throughput capacity in MiB/s. Must be between 4 and
32.

.TP 2m
\fB\-\-throughput\-reservation\fR=\fITHROUGHPUT_RESERVATION\fR

Reservation ID to use for topic throughput.
