dbt-spark 0.21.1 (Release TBD)

Fixes

  • Fix --store-failures for tests, by suppressing irrelevant error in comment_clause() macro (#232, #233)
  • Add support for on_schema_change config in incremental models: ignore, fail, append_new_columns. For sync_all_columns, removing columns is not supported by Apache Spark or Delta Lake (#198, #226, #229)
  • Add persist_docs call to incremental model (#224, #234)

Contributors

dbt-spark 0.21.0 (October 4, 2021)

Fixes

  • Enhanced get_columns_in_relation method to handle a bug in open source deltalake which doesnt return schema details in show table extended in databasename like '*' query output. This impacts dbt snapshots if file format is open source deltalake (#207)
  • Parse properly columns when there are struct fields to avoid considering inner fields: Issue (#202)

Under the hood

  • Add unique_field to better understand adapter adoption in anonymous usage tracking (#211)

Contributors

dbt-spark 0.21.0b2 (August 20, 2021)

Fixes

  • Add pyodbc import error message to dbt.exceptions.RuntimeException to get more detailed information when running dbt debug (#192)
  • Add support for ODBC Server Side Parameters, allowing options that need to be set with the SET statement to be used (#201)
  • Add retry_all configuration setting to retry all connection issues, not just when the _is_retryable_error function determines (#194)

Fixes

Contributors

dbt-spark 0.19.1 (April 2, 2021)

dbt-spark 0.19.1b2 (February 26, 2021)

Under the hood

  • Update serialization calls to use new API in dbt-core 0.19.1b2 (#150)

dbt-spark 0.19.0.1 (February 26, 2021)

Fixes

  • Fix package distribution to include incremental model materializations (#151, #152)

dbt-spark 0.19.0 (February 21, 2021)

Breaking changes

  • Incremental models have incremental_strategy: append by default. This strategy adds new records without updating or overwriting existing records. For that, use merge or insert_overwrite instead, depending on the file format, connection method, and attributes of your underlying data. dbt will try to raise a helpful error if you configure a strategy that is not supported for a given file format or connection. (#140, #141)

Fixes

  • Capture hard-deleted records in snapshot merge, when invalidate_hard_deletes config is set (#109, #126)

dbt-spark 0.19.0rc1 (January 8, 2021)

Breaking changes

  • Users of the http and thrift connection methods need to install extra requirements: pip install dbt-spark[PyHive] (#109, #126)

Under the hood

  • Enable CREATE OR REPLACE support when using Delta. Instead of dropping and recreating the table, it will keep the existing table, and add a new version as supported by Delta. This will ensure that the table stays available when running the pipeline, and you can track the history.
  • Add changelog, issue templates (#119, #120)

Fixes

  • Handle case of 0 retries better for HTTP Spark Connections (#132)

Contributors
