As part of our transformations, we will use Snowflake’s PIVOT construct to turn rows based on individual air quality measurements into a tabular view based on the date, with columns containing air quality averages. This column-based structure is similar to our clima...
The length of output_cols mus match the expected number of output columns from the specific estimator or transformer class used. If this parameter is not specified, output column names are derived by adding an OUTPUT_ prefix to the label column names. These inferred output colum...

Label column setter. Parameters label_cols –A single label column or multiple label columns if multi task learning. Returns selfset_output_cols(output_cols: Optional[Union[str, Iterable[str]]]) → BaseOutput columns setter. Parameters output_cols –A single output column or mult...
In this post, we showcase our amazing Snowflake technology partners and their ways of using the new query function within their respective products.
Within each micro-partition, data is stored in a columnar data structure, allowing better compression and efficient access only to those columns required by a query. As shown in the picture above, 24 rows from the table are stored and sorted in 4 micro-partitions by columns. Repeated values ...
Set the structure property: Columns that define the structure of the dataset. Type: array (or Expression with resultType array), itemType: DatasetDataElement. Overrides: SnowflakeDataset.withStructure(Object structure) Parameters: structure withTable public SnowflakeDataset withTable(Object table) Se...

Which options are correct regarding the data that is stored in micro-partition metadata? The range of values for each of the columns in the micro-partition. The number of distinct values. Additional properties are used for both optimization and efficient query processing. . ...
