dbt-mindsdb 1.0.2
The dbt adapter plugin for connecting to MindsDB

# 🚧 dbt-mindsdb 🚧

The dbt-mindsdb package allows dbt to connect to [MindsDB](https://github.com/mindsdb/mindsdb).


## Installation

Atm, can only be installed from source:

```
git clone git@github.com:mindsdb/dbt-mindsdb.git
python setup.py develop
```

There is an dependency issue with latest dbt-core, so make sure to run:

```
pip install markupsafe==2.0.1
```

## Configurations

Basic `profile.yml` for connecting to MindsDB:

```yml
mindsdb:
  outputs:
    dev:
      database: 'mindsdb'
      host: '127.0.0.1'
      password: ''
      port: 47335
      schema: 'mindsdb'
      type: mindsdb
      username: 'mindsdb'
  target: dev

```

## Usage

- Create dbt project, choose mindsdb database and set up connection
```    
    dbt init <project_name>
```
- To create predictor add dbt model with "predictor" materialization: 
Name of the model is used as name of predictor.
Parameters:
  - integration - name of used integration to get data from and save result to.
    In has to be created in mindsdb beforehand
  - predict - field for prediction
  - predict_alias [optional] - alias for predicted field
  - using [optional] - options for configure trained model
```    
    {{
        config(
            materialized='predictor',
            integration='photorep',
            predict='name',
            predict_alias='name',
            using={
                'encoders.location.module': 'CategoricalAutoEncoder',
                'encoders.rental_price.module': 'NumericEncoder'
            }
        )
    }}
      select * from stores
```

- To apply predictor add dbt model with "table" materialization. 
It creates or replaces table in selected integration with results of predictor.
Name of the model is used as name of the table to store prediction results. 
If you need to specify schema you can do it with dot separator: schema_name.table_name.sql    
Parameters:
  - predictor_name - name of using predictor.
    It has to be created in mindsdb
  - integration - name of used integration to get data from and save result to.
    In has to be created in mindsdb beforehand
```    
    {{ config(materialized='table', predictor_name='TEST_PREDICTOR_NAME', integration='int1') }}
        select a, bc from ddd where name > latest
```
