Fields

input: Option<Box<Relation>>

(Required) Input relation for Group Map API: apply, applyInPandas.

grouping_expressions: Vec<Expression>

(Required) Expressions for grouping keys.

func: Option<CommonInlineUserDefinedFunction>

(Required) Input user-defined function.

sorting_expressions: Vec<Expression>

(Optional) Expressions for sorting. Only used by Scala Sorted Group Map API.

initial_input: Option<Box<Relation>>

Below fields are only used by (Flat)MapGroupsWithState (Optional) Input relation for initial State.

initial_grouping_expressions: Vec<Expression>

(Optional) Expressions for grouping keys of the initial state input relation.

is_map_groups_with_state: Option<bool>

(Optional) True if MapGroupsWithState, false if FlatMapGroupsWithState.

output_mode: Option<String>

(Optional) The output mode of the function.

timeout_conf: Option<String>

(Optional) Timeout configuration for groups that do not receive data for a while.

Implementations

impl GroupMap

pub fn is_map_groups_with_state(&self) -> bool

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

pub fn output_mode(&self) -> &str

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

pub fn timeout_conf(&self) -> &str

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

Trait Implementations

impl Clone for GroupMap

fn clone(&self) -> GroupMap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GroupMap

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

Formats the value using the given formatter.

impl Default for GroupMap

fn default() -> Self

Returns the “default value” for a type.

impl Message for GroupMap

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 GroupMap

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