Final ODBC Release

Final release using the Dremio Arrow Flight ODBC driver.

Requirements for using ODBC will be dropped in subsequent releases.

Release is designated as beta due to lack of full test coverage. However, functionality and performance is same as v1.0.6.5.

Dependencies:

• dbt-core == 1.0.6
• pyodbc >= 4.0.27
• Dremio Software >= 21.0.0
• dremio.iceberg.enabled, dremio.iceberg.ctas.enabled and dremio.execution.support_unlimited_splits enabled
• Dremio's Arrow Flight SQL ODBC driver

Adapter works with both Dremio Software and Dremio Cloud.

When creating projects using Dremio Cloud, add the following to the bottom of the dbt_proctted.yml file:

vars:
  dremio:reflections_enabled: false

Note that the above may be required in projects connecting to Dremio Software.
