DOOR (Do Our Own Research) - SQL Models

This repository contains DBT SQL Models that glue together and transform low-level tables into analytics ready data sets. The tables that are output from this DBT project are available to Flipside users here in Velocity

The framework used to manage SQL table composition is DBT and we use Snowflake as our Data Warehouse.

Upgrading to DBT Version 1.0 for Local Development

We are now using DBT version 1.0 for this project. Follow the instructions below for your operating system to upgrade your local development environment.

MacOS If you originally installed dbt using home brew, upgrade it using the below command

brew update
brew upgrade dbt-snowflake
brew link --overwrite dbt-snowflake

Windows

pip install --upgrade dbt-core
pip install --upgrade dbt-snowflake

After running the upgrade commands, run dbt --versions to check you are now on v1.0

For both systems you will need to re-run your dbt dependencies which will be installed in dbt_packages instead of dbt_modules

dbt deps

Getting Started

Step1: Install the DBT command line tool on your local machine. Instructions here at DBT.

Step2: Configure your "profile" a.k.a the credentials that DBT will use locally to connect to Snowflake. Open a bash terminal and run nano ~/.dbt/profiles.yml. Copy and paste the below code in with your credentials that were provided by Flipside (replacing the variables in "<>" below).

snowflake:
    target: dev
    outputs:
        dev:
            type: snowflake
            account: <account>
            user: <username>
            password: <password>
            role: <role>
            region: <region>
            database: <database>
            warehouse: <warehouse>
            schema: <schema>
            threads: 4
            client_session_keep_alive: False
            query_tag: dbt
    config:
        send_anonymous_usage_stats: False

Step3: Test your config is working properly by running opening a bash terming in the directory of this project and running: dbt run --models +tag:uniswapv3. This command, if working properly, will do an incremental refresh of the uniswapv3 models found in models/uniswapv3/.

Conventions

File Names

We use two underscores in our model filenames __ to denote the schema and table. For example {schema}__{tablename}.sql. We have configured a custom DBT macro that will split the filenames in this manner when creating the actual tables in snowflake. If the file name is ethereum__transactions.sql, the schema in snowflake will be ethereum and the table name will be transactions, queryable at ethereum.transactions.

Contributing

If you would like to contribute a new model/table to our Velocity product, please create a new branch, and once you are ready create a pull request with the following information: the goal of the PR, and the tables that will be produced by the PR. After submitting the PR a member of our analytics team will review it. If approved the models you produce here will be made available for querying in Flipside's Velocity product.

Source Data

Source tables that can be used when building models are outline here: models/sources.yml. The majority of tables you will use as source to your models can be found in Flipside's silver schema.

Supported Extensions

Extensions provide predefined blocks, functions, tests.

• dbt expectations
• dbt utils
• dbt date

Commands

Install extensions. This only needs to be run once.

dbt deps

Run a model by matching on tag. In this case let's run all UniswapV3 models:

dbt run --models +tag:uniswapv3

Now let's do a full refresh of uniswapv3.

dbt run --models +tag:uniswapv3 --full-refresh

Run DBT tests

dbt test
