Apache Gravitino Command Line Interface

This document provides guidance on managing metadata within Apache Gravitino using the Command Line Interface (CLI). The CLI offers a terminal based alternative to using code or the REST interface for metadata management.

Currently, the CLI allows users to view metadata information for metalakes, catalogs, schemas, tables, users, roles, groups, tags, topics and filesets. Future updates will expand on these capabilities.

Running the CLI

You can configure an alias for the CLI for ease of use, with the following command:

alias gcli='java -jar ../../cli/build/libs/gravitino-cli-*-incubating-SNAPSHOT.jar'

Or you use the gcli.sh script found in the clients/cli/bin/ directory to run the CLI.

Usage

f The general structure for running commands with the Gravitino CLI is gcli entity command [options].

 usage: gcli [metalake|catalog|schema|model|table|column|user|group|tag|topic|fileset] [list|details|create|delete|update|set|remove|properties|revoke|grant] [options]

Commands

The following commands are used for entity management:

• list: List available entities
• details: Show detailed information about an entity
• create: Create a new entity
• delete: Delete an existing entity
• update: Update an existing entity
• set: Set a property on an entity
• remove: Remove a property from an entity
• properties: Display an entities properties

Setting the Metalake name

As dealing with one Metalake is a typical scenario, you can set the Metalake name in several ways so it doesn't need to be passed on the command line.

1. Passed in on the command line via the --metalake parameter.
2. Set via the GRAVITINO_METALAKE environment variable.
3. Stored in the Gravitino CLI configuration file.

The command line option overrides the environment variable and the environment variable overrides the configuration file.

Setting the Gravitino URL

As you need to set the Gravitino URL for every command, you can set the URL in several ways.

1. Passed in on the command line via the --url parameter.
2. Set via the 'GRAVITINO_URL' environment variable.
3. Stored in the Gravitino CLI configuration file.

The command line option overrides the environment variable and the environment variable overrides the configuration file.

Setting the Gravitino Authentication Type

The authentication type can also be set in several ways.

1. Passed in on the command line via the --simple flag.
2. Set via the 'GRAVITINO_AUTH' environment variable.
3. Stored in the Gravitino CLI configuration file.

Gravitino CLI configuration file

The gravitino CLI can read commonly used CLI options from a configuration file. By default, the file is .gravitino in the user's home directory. The metalake, URL and ignore parameters can be set in this file.

#
# Gravitino CLI configuration file
#

# Metalake to use
metalake=metalake_demo

# Gravitino server to connect to
URL=http://localhost:8090

# Ignore client/server version mismatch
ignore=true

# Authentication
auth=simple

OAuth authentication can also be configured via the configuration file.

# Authentication
auth=oauth
serverURI=http://127.0.0.1:1082
credential=xx:xx
token=test
scope=token/test

Kerberos authentication can also be configured via the configuration file.

# Authentication
auth=kerberos
principal=user/admin@foo.com
keytabFile=file.keytab

Potentially unsafe operations

For operations that delete data or rename a metalake the user with be prompted to make sure they wish to run this command. The --force option can be specified to override this behaviour.

Manage metadata

All the commands are performed by using the Java API internally.

Display help

To display help on command usage:

gcli --help

Display client version

To display the client version:

gcli --version

Display server version

To display the server version:

gcli --server

Client/server version mismatch

If the client and server are running different versions of the Gravitino software then you may need to ignore the client/server version check for the command to run. This can be done in several ways:

1. Passed in on the command line via the --ignore parameter.
2. Set via the GRAVITINO_IGNORE environment variable.
3. Stored in the Gravitino CLI configuration file.

Multiple properties

For commands that accept multiple properties they can be specified in a couple of different ways:

1. gcli --properties n1=v1,n2=v2,n3=v3

2. gcli --properties n1=v1 n2=v2 n3=v3

3. gcli --properties n1=v1 --properties n2=v2 --properties n3=v3

Setting properties and tags

Different options are needed to add a tag and set a property of a tag with gcli tag set. To add a tag, specify the tag (via --tag) and the entity to tag (via --name). To set the property of a tag (via --tag) you need to specify the property (via --property) and value (via --value) you want to set.

To delete a tag, again, you need to specify the tag and entity, to remove a tag's property you need to select the tag and property.

Please set the metalake in the Gravitino configuration file or the environment variable before running any of these commands.

Not all of the columns need to be specifed just the name and datatype columns. If not specified comment default to null, nullability to true and auto increment to false. If only the default value is specified it defaults to the same data type as the column.
