dbt 0.15.0

dbt 0.15.0 (November 25, 2019)

Breaking changes

• Support for Python 2.x has been dropped as it will no longer be supported on January 1, 2020
• Compilation errors in .yml files are now treated as errors instead of warnings (#1493, #1751)
• The 'table_name' field field has been removed from Relations
• The existing compile and execute rpc tasks have been renamed to compile_sql and execute_sql (#1779, #1798) (docs)
• Custom materializations must now manage dbt's Relation cache (docs)

Installation notes:

dbt v0.15.0 uses the psycopg2-binary dependency (instead of psycopg2) to simplify installation on platforms that do not have a compiler toolchain installed. pip users should run pip uninstall psycopg2 before upgrading their version of dbt to 0.15.0. If after upgrading you experience segmentation faults, crashes, or installation errors, you can set the DBT_PSYCOPG2_NAME environment variable to psycopg2 to change the dependency that dbt installs. This may require a compiler toolchain and development libraries.

$ DBT_PSYCOPG2_NAME=psycopg2 pip install dbt

You may also install specific dbt plugins directly by name. This has the advantage of only installing the Python requirements needed for your particular database:

# Installing dbt-snowflake and dbt-bigquery directly bypasses the psycopg2 dependency
$ pip install dbt-snowflake
$ pip install dbt-bigquery

# Installing dbt-postgres and dbt-redshift are also supported
$ pip install dbt-postgres
$ pip install dbt-redshift

dbt 0.13.0

dbt 0.13.0 - Stephen Girard (March 21, 2019)

Overview

This release provides a stable API for building new adapters and reimplements dbt's adapters as "plugins". Additionally, a new adapter for Presto was added using this architecture. Beyond adapters, this release of dbt also includes Sources which can be used to document and test source data tables. See the full list of features added in 0.13.0 below.

Links:

• Discussion (Discourse)
• Changelog

Installation instructions

dbt v0.13.0 is available on Homebrew, PyPi, and in dbt Cloud.

# Homebrew
$ brew install dbt

# pip
$ pip install dbt

Note: If you're upgrading from an earlier version of dbt using pip, you may need to install dbt with the -I flag. This flag is required due to changes in the structure of the dbt package.

$ pip install -I dbt

For full installation instructions, consult the docs

Breaking Changes

• Version 1 schema.yml specs are no longer implemented. Please use the version 2 spec instead (migration guide)

• A number of materialization-specific adapter methods have changed in breaking ways. If you use these adapter methods in your macros or materializations, you may need to update your code accordingly.
  • query_for_existing - removed, use get_relation instead.
  • get_missing_columns - changed to take Relations instead of schemas and identifiers
  • expand_target_column_types - changed to take a Relation instead of schema, identifier
  • get_relation - added a database argument
  • create_schema - added a database argument
  • drop_schema - added a database argument

Deprecations

Stephen Girard

Can you imagine buying the Federal Reserve? That’s how rich Stephen Girard was. The First Bank of the United States, Alexander Hamilton’s brainchild, ran out its charter in 1811 and Girard decided it was a steal. Estimated to be the 4th richest American ever, he just up and bought it.

Not satisfied with one bank, Girard went for more. With the British invading in 1812, Girard put everything on the line and underwrote nearly all the US war bonds. Without this capital, we would likely all have British accents today. In return, the US made Girard a major shareholder of the Second Bank of the United States when it was founded.

Buying government bonds: dépassé.
Buying governments: branché.

Girard, who had no children, was one of America’s biggest philanthropists. He single-handedly endowed the 43-acre Girard College to educate “poor, male, white orphans,” inspired by his own hard-scrabble early life. Thankfully, its target demographic has since broadened—its first African-American student was admitted in 1968 and its first female student was admitte...
