When set to true, the provider will enable dictionary encoding when creating .parquet files using Create Table Statement and Bulk Inserts.

Data Type

bool

Default Value

true

Remarks

When set to true, the provider will enable dictionary encoding when creating .parquet files using Create Table Statement and Bulk Inserts. Using dictionary encoding can help reduce size of the resultant .parquet file if a column has repeated values. Columns with all unique values will not use dictionary encoding even if this property is set to true.
