CLI for Firebolt

Firebolt-CLI

Firebolt cli is a tool for connecting to firebolt, managing firebolt resources, and executing queries from the command line.

Quickstart

Prerequisites

python>=3.7 and pip should be installed beforehand. For this go to Python official page.

Also, you will need a firebolt account with information about username, password, database, and engine. For more information go to Firebolt.

Installation

Once you have all prerequisites in place, you can install the firebolt cli via pip:

$ pip install firebolt-cli

To verify the installation run:

$ firebolt --version

firebolt, version 0.2.0

Running

The next step is to configure the firebolt cli:

$ firebolt configure

Username [None]: your_username
Password [None]: ********
Account name [None]: your_firebolt_account_name
Database name [None]: your_database
Engine name or URL [None]: your_engine_name_or_url
Successfully updated firebolt-cli configuration

To run your first query, the engine has to be running. Check the status of the engine by executing the following command:

$ firebolt engine status your_engine_name

Engine your_engine_name current status is: ENGINE_STATUS_SUMMARY_STOPPED

If the engine is stopped, you have to start the engine by executing the following command:

$ firebolt engine start your_engine_name --wait

Engine your_engine_name is successfully started

Now you are ready to run your first query, this could be done by opening the interactive query

$ firebolt query

$ firebolt query --username your_user_name \
                 --engine-name your_running_engine

3. Use environment variable

$ export FIREBOLT_USERNAME=your_username
$ export FIREBOLT_PASSWORD=your_password
$ export FIREBOLT_ACCOUNT_NAME=your_account_name
$ export FIREBOLT_API_ENDPOINT=api_endpoint
$ export FIREBOLT_ENGINE_NAME_URL=your_engine_name_or_url
$ export FIREBOLT_ACCESS_TOKEN=access_token
$ firebolt query

Interactive SQL

To enter interactive SQL, firebolt CLI has to be configured using one of three methods from configuration section. Then simply run

$ firebolt query

firebolt> .help
.exit     Exit firebolt-cli
.help     Show this help message
.quit     Exit firebolt-cli
.tables   Show tables in current database
firebolt>

Interactive SQL mode also supports multiline commands and multiple statements;

firebolt> SELECT * FROM your_table
     ...> ORDER BY l_shipdate
     ...> LIMIT 2;

Enable shell completion

Firebolt provides tab completion for Bash (version 4.4 and up), Zsh, and Fish. In order to enable the completion for your environment you have to follow one of the steps below.

Bash

Add this to ~/.bashrc:

eval "$(_FIREBOLT_COMPLETE=bash_source firebolt)"

Zsh

Add this to ~/.zshrc:

eval "$(_FIREBOLT_COMPLETE=zsh_source firebolt)"

Fish

Add this to ~/.config/fish/completions/firebolt.fish:

eval (env _FIREBOLT_COMPLETE=fish_source firebolt)

The completion in firebolt-cli is based on Click library. For more information please visit Click documentation.

Docker

To start the work with docker, you should first pull the docker from the repository.

docker pull ghcr.io/firebolt-db/firebolt-cli:latest

Afterward, you will be able to run the cli and passing all configuration variables as environment variables.

Here is an example of getting a list of available engines:

docker run -e FIREBOLT_USERNAME="your_username"\
           -e FIREBOLT_PASSWORD="your_password"\  
           ghcr.io/firebolt-db/firebolt-cli:latest engine list
