Expand description

The base configurations to provide when creating a physical plan for writing to any given file format.

Fields§

§object_store_url: ObjectStoreUrl

Object store URL, used to get an ObjectStore instance

§file_groups: Vec<PartitionedFile>

A vector of PartitionedFile structs, each representing a file partition

§table_paths: Vec<ListingTableUrl>

Vector of partition paths

§output_schema: SchemaRef

The schema of the output file

§table_partition_cols: Vec<(String, DataType)>

A vector of column names and their corresponding data types, representing the partitioning columns for the file

§insert_op: InsertOp

Controls how new data should be written to the file, determining whether to append to, overwrite, or replace records in existing files.

§keep_partition_by_columns: bool

Controls whether partition columns are kept for the file

§file_extension: String

File extension without a dot(.)
