Struct WriteOperationV2

pub struct WriteOperationV2 {
    pub input: Option<Relation>,
    pub table_name: String,
    pub provider: Option<String>,
    pub partitioning_columns: Vec<Expression>,
    pub options: HashMap<String, String>,
    pub table_properties: HashMap<String, String>,
    pub mode: i32,
    pub overwrite_condition: Option<Expression>,
}

As writes are not directly handled during analysis and planning, they are modeled as commands.

Fields

input: Option<Relation>

(Required) The output of the input relation will be persisted according to the options.

table_name: String

(Required) The destination of the write operation must be either a path or a table.

provider: Option<String>

(Optional) A provider for the underlying output data source. Spark’s default catalog supports “parquet”, “json”, etc.

partitioning_columns: Vec<Expression>

(Optional) List of columns for partitioning for output table created by create, createOrReplace, or replace

options: HashMap<String, String>

(Optional) A list of configuration options.

table_properties: HashMap<String, String>

(Optional) A list of table properties.

mode: i32

(Required) Write mode.

overwrite_condition: Option<Expression>

(Optional) A condition for overwrite saving mode

Implementations

impl WriteOperationV2

pub fn provider(&self) -> &str

Returns the value of provider, or the default value if provider is unset.

pub fn mode(&self) -> Mode

Returns the enum value of mode, or the default if the field is set to an invalid enum value.

pub fn set_mode(&mut self, value: Mode)

Sets mode to the provided enum value.

Trait Implementations

impl Clone for WriteOperationV2

fn clone(&self) -> WriteOperationV2

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WriteOperationV2

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for WriteOperationV2

fn default() -> Self

Returns the “default value” for a type.

impl Message for WriteOperationV2

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for WriteOperationV2

fn eq(&self, other: &WriteOperationV2) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
