A first release candidate for dbt-core v1.0.0. Includes everything in b1 + b2, plus:

Breaking changes

  • Replace greedy flag/property for test selection with indirect_selection: eager/cautious flag/property. Set to eager by default. Note: This reverts test selection to its pre-v0.20 behavior by default. dbt test -s my_model will select multi-parent tests, such as relationships, that depend on unselected resources. To achieve the behavior change in v0.20 + v0.21, set --indirect-selection=cautious on the CLI or indirect_selection: cautious in yaml selectors. (#4082, #4104)
  • In v1.0.0, pip install dbt will raise an explicit error. Instead, please use pip install dbt-<adapter> (to use dbt with that database adapter), or pip install dbt-core (for core functionality). For parity with the previous behavior of pip install dbt, you can use: pip install dbt-core dbt-postgres dbt-redshift dbt-snowflake dbt-bigquery (#4100, #4133)
  • Reorganize the global_project (macros) into smaller files with clearer names. Remove unused global macros: column_list, column_list_for_create_table, incremental_upsert (#4154)
  • Introduce structured event interface, and begin conversion of all legacy logging (#3359, #4055)
    • This is a breaking change for adapter plugins, requiring a very simple migration. See events module README for details.
    • If you maintain another kind of dbt-core plugin that makes heavy use of legacy logging, and you need time to cut over to the new event interface, you can re-enable the legacy logger via an environment variable shim, DBT_ENABLE_LEGACY_LOGGER=True. Be advised that we will remove this capability in a future version of dbt-core.

Features

  • Allow nullable error_after in source freshness (#3874, #3955)
  • Add metrics nodes (#4071, #4235)
  • Add support for dbt init <project_name>, and support for skip_profile_setup argument (dbt init -s) (#4156, #4249)

Fixes

  • Changes unit tests using assertRaisesRegexp to assertRaisesRegex (#4136, #4136)
  • Allow retries when the answer from a dbt deps is None (#4178, #4225)

Docs

  • Fix non-alphabetical sort of Source Tables in source overview page (docs#81, docs#218)
  • Add title tag to node elements in tree (docs#202, docs#203)
  • Account for test rename: schema → generic, data → singular. Use test_metadata instead of schema/data tags to differentiate (docs#216, docs#222)
  • Add metrics (core#216, docs#223)

Under the hood

  • Bump artifact schema versions for 1.0.0: manifest v4, run results v4, sources v3. Notable changes: added metrics nodes; schema test + data test nodes are renamed to generic test + singular test nodes; freshness threshold default values (#4191)
  • Speed up node selection by skipping incorporate_indirect_nodes if not needed (#4213, #4214)
  • When on_schema_change is set, pass common columns as dest_columns in incremental merge macros (#4144, #4170)
  • Clear adapters before registering in lib module config generation (#4218)
  • Remove official support for python 3.6, which is reaching end of life on December 23, 2021 (#4134, #4223)
