Databricks Delta Live Tables (DLT) Pipeline

ATTRIBUTE	DESCRIPTION
access_controls	Pipeline access controls TYPE: list[AccessControl]
allow_duplicate_names	If False, deployment will fail if name conflicts with that of another pipeline. TYPE: bool
catalog	Name of the unity catalog storing the pipeline tables TYPE: Union[str, None]
channel	Name of the release channel for Spark version used by DLT pipeline. TYPE: Literal['CURRENT', 'PREVIEW']
clusters	Clusters to run the pipeline. If none is specified, pipelines will automatically select a default cluster configuration for the pipeline. TYPE: list[PipelineCluster]
configuration	List of values to apply to the entire pipeline. Elements must be formatted as key:value pairs TYPE: dict[str, str]
continuous	If True, the pipeline is run continuously. TYPE: bool
development	If True the pipeline is run in development mode TYPE: Union[bool, str]
edition	Name of the product edition TYPE: Literal['CORE', 'PRO', 'ADVANCED']
libraries	Specifies pipeline code (notebooks) and required artifacts. TYPE: list[PipelineLibrary]
name	Pipeline name TYPE: str
notifications	Notifications specifications TYPE: list[PipelineNotifications]
photon	If True, Photon engine enabled. TYPE: bool
serverless	If True, serverless is enabled TYPE: bool
storage	A location on DBFS or cloud storage where output data and metadata required for pipeline execution are stored. By default, tables are stored in a subdirectory of this location. Change of this parameter forces recreation of the pipeline. (Conflicts with catalog). TYPE: str
target	The name of a database (in either the Hive metastore or in a UC catalog) for persisting pipeline output data. Configuring the target setting allows you to view and query the pipeline output data from the Databricks UI. TYPE: str

Examples:

Assuming the configuration yaml file

import io
from laktory import models

# Define pipeline
pipeline_yaml = '''

      path: /pipelines/dlt_brz_template.py
  - notebook:
      path: /pipelines/dlt_slv_template.py
  - notebook:
      path: /pipelines/dlt_gld_stock_performances.py

access_controls:
  - group_name: account users
    permission_level: CAN_VIEW
  - group_name: role-engineers
    permission_level: CAN_RUN
