.TP 2m
\fB\-\-expiration\fR=\fIEXPIRATION\fR

How long after creation should this table or view expire e.g. 1d, 2w etc.

See $ gcloud topic datetimes for information on duration formats

.TP 2m
\fB\-\-relax\-columns\fR=[\fIFIELD_NAME\fR,...]

A comma\-separated list of field names in the current schema that should have
their mode changed from REQUIRED to NULLABLE.

For more details on updating and managing BigQuery schemas see:
https://cloud.google.com/bigquery/docs/managing\-table\-schemas

.TP 2m

Specify changes to the table schema.

At most one of these can be specified:


.RS 2m
.TP 2m
\fB\-\-add\-columns\fR=[\fIFIELD_NAME\fR=\fIFIELD_TYPE\fR,...]

A comma\-separated list of entries of the form FIELD_NAME[=FIELD_TYPE]
specifying field names and types for the columns being added to the table.
FIELD_TYPE defaults to string if not present. Possible FIELD_TYPES are
\f5string\fR, \f5integer\fR, \f5float\fR, \f5boolean\fR, \f5record\fR, and
