Improvements

Upgraded JDBC to 3.19.0.
Changed the internal file format from Json to Parquet when loading structured data.
- Introduced a new parameter use_json_in_structured_data, which default to false. Once enabled, this change will be revoked.

New Features

Supported Parquet file format when loading data from Spark to Snowflake.
- Introduced a new parameter use_parquet_in_write, which default to false. When enabled, Spark connector will only use Parquet file format when loading data from Spark to Snowflake.
- Introduced a new dependency parquet-avro. The default version is 1.13.1. Since its dependency, parquet-column, is a Spark built-in lib, an incompatible issue may be occurred during runtime. Please manually adjust the version of parquet-avro to fix this issue.
