transform(dataset, paramsopt, …otherParamPairsopt) → {module:eclairjs/sql.Dataset}

Transforms the dataset with optional parameters
Parameters:
Name Type Attributes Description
dataset module:eclairjs/sql.Dataset input dataset
params module:eclairjs/ml/param.ParamMap | module:eclairjs/ml/param.ParamPair <optional>
 additional parameters, overwrite embedded params, overwrite embedded params
otherParamPairs module:eclairjs/ml/param.ParamPair <optional>
<repeatable>
 other param pairs, Only used if argument two is module:eclairjs/ml/param.ParamPair. Overwrite embedded params

Returns:
transformed dataset
Type
module:eclairjs/sql.Dataset

transformSchema() → {module:eclairjs/sql/types.StructType}

Check transform validity and derive the output schema from the input schema. Typical implementation should first conduct verification on schema change and parameter validity, including complex parameter interaction checks. * @param {module:eclairjs/sql/types.StructType} schema
