.SH "DESCRIPTION"

\fB(ALPHA)\fR Create a new Dataproc Metastore federation with the given name and
configurations.

If run asynchronously with \f5\-\-async\fR, exits after printing one operation
name that can be used to poll the status of the creation via:

.SH "EXAMPLES"

To create a Dataproc Metastore federation with the name
\f5my\-metastore\-federation\fR in location \f5us\-central\fR with two backends
\f5dpms1\fR and \f5dpms2\fR, run:

.RS 2m
$ gcloud alpha metastore federations create \e
  my\-metastore\-federation \-\-location=us\-central1 \e
  \-\-backends=1=dpms:dpms1,2=dpms:projects/my\-project/locations/\e

.SH "POSITIONAL ARGUMENTS"

.RS 2m
.TP 2m

Federation resource \- Arguments and flags that specify the Dataproc Metastore
federation you want to create. The arguments in this group can be used to
specify the attributes of this resource. (NOTE) Some attributes are not given
arguments in this group but can be set in other ways.

To set the \f5project\fR attribute:
.RS 2m
.IP "\(em" 2m
provide the argument \f5federation\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.
.RE
.sp

This must be specified.


.RS 2m
.TP 2m
\fIFEDERATION\fR

ID of the federation or fully qualified identifier for the federation.

To set the \f5federation\fR attribute:
.RS 2m
.IP "\(bu" 2m
provide the argument \f5federation\fR on the command line.
.RE
.sp

This positional argument must be specified if any of the other arguments in this
group are specified.

.TP 2m
\fB\-\-location\fR=\fILOCATION\fR

The location of the Dataproc Metastore service.

If not specified, will use \f5default\fR metastore/location.


To set the \f5location\fR attribute:
.RS 2m
.IP "\(bu" 2m
provide the argument \f5federation\fR on the command line with a fully specified
name;
.IP "\(bu" 2m
provide the argument \f5\-\-location\fR on the command line;
.IP "\(bu" 2m
set the property \f5metastore/location\fR.

.SH "REQUIRED FLAGS"

.RS 2m
.TP 2m
\fB\-\-backends\fR=\fIRANK\fR=\fIBACKEND\fR

Backends from which the federation service serves metadata at query time. The
backends are specified as a comma\-separated list of \f5RANK=BACKEND\fR pairs.
For example:
\f51=dpms:dpms1,2=dpms:projects/my\-project/locations/us\-central1/services/dpms2\fR.
\f5RANK\fR represents the rank of the backend metastore and is used to resolve
database name collisions. \f5BACKEND\fR is specified as
\f5METASTORE_TYPE:METASTORE_NAME\fR where \f5METASTORE_TYPE\fR is the type of
backend metastore and \f5METASTORE_NAME\fR is the relative resource name of the
metastore. If only the name of the metastore is specified (e.g. \f5dpms1\fR),
project and location will be inferred from the project and location used to
create the federation.

.SH "OPTIONAL FLAGS"

.RS 2m
.TP 2m
\fB\-\-async\fR

Return immediately, without waiting for the operation in progress to complete.

.TP 2m
\fB\-\-hive\-metastore\-version\fR=\fIHIVE_METASTORE_VERSION\fR

Hive metastore schema version of the Metastore federation.
\fIHIVE_METASTORE_VERSION\fR must be one of: \fB2.3.6\fR, \fB3.1.2\fR.

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

List of label KEY=VALUE pairs to add.

Keys must start with a lowercase character and contain only hyphens (\f5\-\fR),
underscores (\f5_\fR), lowercase characters, and numbers. Values must contain
only hyphens (\f5\-\fR), underscores (\f5_\fR), lowercase characters, and
numbers.

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

List of tag KEY=VALUE pairs to add.
