This plugin allows vdk-core to interface with and execute queries against a Trino database. Additionally, it can collect lineage data, assuming a lineage logger has been provided through the vdk-core configuration.
Usage
Run
pip install vdk-tino
After this data jobs will have access to Trino database connection managed by Versatile Data Kit SDK.
If it is the only database plugin installed , vdk would automatically use it. Otherwise, users need to set VDK_DB_DEFAULT_TYPE=TRINO as an environment variable or set 'db_default_type' option in the data job config file (config.ini).
For example
def run(job_input: IJobInput):
job_input.execute_query("select 'Hi Trino!'")
Templates
vdk-trino comes with pre-defined templates for SQL transformations
- SCD1 - Slowly Changing Dimension type 1:
- SCD2 - Slowly Changing Dimension Type 2:
Lineage
The package gathers lineage data for all Trino SQL queries executed in a data job
Other plugins can read that lineage data log it. They need to provide LineageLogger implementation and hook this way:
@hookimpl
def vdk_initialize(context: CoreContext) -> None:
context.state.set(StoreKey[LineageLogger]("trino-lineage-logger"), MyLogger())
Configuration
Run vdk config-help - search for those prefixed with "TRINO_" to see what configuration options are available.
