Hi everyone, I wanted to share an update on the status of the migration.
Since Ian’s original email, we’ve migrated code for the BigQuery (Go), Databricks (C#, Go), and Snowflake (Go) drivers from apache/arrow-adbc to their corresponding repositories under the adbc-divers org: - https://github.com/adbc-drivers/bigquery - https://github.com/adbc-drivers/databricks - https://github.com/adbc-drivers/snowflake To continue the migration, I’d like to propose removing these drivers from the apache/arrow-adbc source tree in the ADBC 24 release (23 is in the works now). I’ll start by coordinating with the teams at Databricks and Snowflake and filing separate PRs for each removal. Please let me know if you have any questions or concerns.
