Struct WriteStreamOperationStart

pub struct WriteStreamOperationStart {
    pub input: Option<Relation>,
    pub format: String,
    pub options: HashMap<String, String>,
    pub partitioning_column_names: Vec<String>,
    pub output_mode: String,
    pub query_name: String,
    pub foreach_writer: Option<StreamingForeachFunction>,
    pub foreach_batch: Option<StreamingForeachFunction>,
    pub trigger: Option<Trigger>,
    pub sink_destination: Option<SinkDestination>,
}

Starts write stream operation as streaming query. Query ID and Run ID of the streaming query are returned.

Fields

input: Option<Relation>

(Required) The output of the input streaming relation will be written.

format: String

options: HashMap<String, String>

partitioning_column_names: Vec<String>

output_mode: String

query_name: String

foreach_writer: Option<StreamingForeachFunction>

foreach_batch: Option<StreamingForeachFunction>

trigger: Option<Trigger>

sink_destination: Option<SinkDestination>

The destination is optional. When set, it can be a path or a table name.

Trait Implementations

impl Clone for WriteStreamOperationStart

fn clone(&self) -> WriteStreamOperationStart

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WriteStreamOperationStart

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

impl Default for WriteStreamOperationStart

fn default() -> Self

Returns the “default value” for a type.

impl Message for WriteStreamOperationStart

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 WriteStreamOperationStart

fn eq(&self, other: &WriteStreamOperationStart) -> 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.
