Struct FastInsertRequest

pub struct FastInsertRequest {
    pub table_id: u32,
    pub table_version_id: u64,
    pub column_indices: Vec<u32>,
    pub data_chunk: Option<DataChunk>,
    pub row_id_index: Option<u32>,
    pub request_id: u32,
    pub wait_for_persistence: bool,
}

Fields

table_id: u32

Id of the table to perform inserting.

table_version_id: u64

Version of the table.

column_indices: Vec<u32>

data_chunk: Option<DataChunk>

row_id_index: Option<u32>

An optional field and will be None for tables without user-defined pk. The BatchInsertExecutor should add a column with NULL value which will be filled in streaming.

request_id: u32

Use this number to assign the insert req to different worker nodes and dml channels.

wait_for_persistence: bool

TODO(kexiang): add support for default columns. plan_common.ExprContext expr_context is needed for it.

Trait Implementations

impl Clone for FastInsertRequest

fn clone(&self) -> FastInsertRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FastInsertRequest

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

Formats the value using the given formatter.

impl Default for FastInsertRequest

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FastInsertRequest

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for FastInsertRequest

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where 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( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where 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(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

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

where Self: Default,

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

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

where Self: Sized,

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

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

where Self: Sized,

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

impl PartialEq for FastInsertRequest

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

impl Serialize for FastInsertRequest

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
