Class ParquetReadOptions

java.lang.Object

org.apache.datafusion.ParquetReadOptions

public final class ParquetReadOptions
extends Object

Configuration knobs for parquet sources passed to SessionContext.registerParquet(String, String, ParquetReadOptions) and SessionContext.readParquet(String, ParquetReadOptions).

Mirrors a subset of DataFusion's ParquetReadOptions. All setters return this for fluent chaining. Defaults: fileExtension = ".parquet"; all other fields null (meaning the SessionConfig default is used, or the schema is inferred from the file).
