0.2.0a20

0.2.0a17

What's Changed

• adds duckdb destination and dbt support by @rudolfix in #124
  The 🦆 db destination is added and may be used like any other destination. The multithreaded loading is quite fast thanks to duckdb dropping the GIL when called. See more in our docs
  We also support the dbt-duckdb adapter, the jaffle shop example was converted to duckdb to showcase this ability

• transaction support was added to sql_client and Big Query got multi-statement transactions via Sessions

Full Changelog: 0.2.0a16...0.2.0a17

0.2.0a16

What's Changed

• uses structured data types to store json by @rudolfix in #121
• brings back the functionality to run dbt packages by @rudolfix in #122

This update changes how the complex data type is being stored. Most often complex data type is generated to hold json data when nesting_level is limited in the source. The complex types are stored as JSONB (postgres), SUPER (redshift), JSON (BigQuery)

This update also allows to easily run dbt packages together with dlt pipelines. Most of the work went into making it user friendly and avoiding any dependency conflicts. This feature is also quite well tested. Take a look at those two examples:
https://github.com/dlt-hub/dlt/blob/devel/docs/examples/dbt_run_jaffle.py
https://github.com/dlt-hub/dlt/blob/devel/docs/examples/chess/chess_dbt.py
https://github.com/dlt-hub/dlt/tree/devel/docs/examples/chess/dbt_transform

Runing the dbt package is just two lines and you have more control over it that with the CLI

0.1.0a15

• docstings and cli improvements by @rudolfix in #114
• allows hash mismatch when loading schema that needs migration
• makes full_refresh flag configurable
• fixes config/secrets injection when union with base configuration is used, fixes secret hint detection
• properly restores pipeline state when extract step fails
