Struct SparkSqlBuilder 

#[non_exhaustive]
pub struct SparkSqlBuilder { /* private fields */ }

A builder for SparkSql.

Implementations

impl SparkSqlBuilder

pub fn name(self, input: impl Into<String>) -> Self

The name of the transform node.

This field is required.

pub fn set_name(self, input: Option<String>) -> Self

The name of the transform node.

pub fn get_name(&self) -> &Option<String>

The name of the transform node.

pub fn inputs(self, input: impl Into<String>) -> Self

Appends an item to inputs.

To override the contents of this collection use set_inputs.

The data inputs identified by their node names. You can associate a table name with each input node to use in the SQL query. The name you choose must meet the Spark SQL naming restrictions.

pub fn set_inputs(self, input: Option<Vec<String>>) -> Self

The data inputs identified by their node names. You can associate a table name with each input node to use in the SQL query. The name you choose must meet the Spark SQL naming restrictions.

pub fn get_inputs(&self) -> &Option<Vec<String>>

The data inputs identified by their node names. You can associate a table name with each input node to use in the SQL query. The name you choose must meet the Spark SQL naming restrictions.

pub fn sql_query(self, input: impl Into<String>) -> Self

A SQL query that must use Spark SQL syntax and return a single data set.

This field is required.

pub fn set_sql_query(self, input: Option<String>) -> Self

A SQL query that must use Spark SQL syntax and return a single data set.

pub fn get_sql_query(&self) -> &Option<String>

A SQL query that must use Spark SQL syntax and return a single data set.

pub fn sql_aliases(self, input: SqlAlias) -> Self

Appends an item to sql_aliases.

To override the contents of this collection use set_sql_aliases.

A list of aliases. An alias allows you to specify what name to use in the SQL for a given input. For example, you have a datasource named "MyDataSource". If you specify From as MyDataSource, and Alias as SqlName, then in your SQL you can do:

select * from SqlName

and that gets data from MyDataSource.

pub fn set_sql_aliases(self, input: Option<Vec<SqlAlias>>) -> Self

A list of aliases. An alias allows you to specify what name to use in the SQL for a given input. For example, you have a datasource named "MyDataSource". If you specify From as MyDataSource, and Alias as SqlName, then in your SQL you can do:

select * from SqlName

and that gets data from MyDataSource.

pub fn get_sql_aliases(&self) -> &Option<Vec<SqlAlias>>

A list of aliases. An alias allows you to specify what name to use in the SQL for a given input. For example, you have a datasource named "MyDataSource". If you specify From as MyDataSource, and Alias as SqlName, then in your SQL you can do:

select * from SqlName

and that gets data from MyDataSource.

pub fn output_schemas(self, input: GlueSchema) -> Self

Appends an item to output_schemas.

To override the contents of this collection use set_output_schemas.

Specifies the data schema for the SparkSQL transform.

pub fn set_output_schemas(self, input: Option<Vec<GlueSchema>>) -> Self

Specifies the data schema for the SparkSQL transform.

pub fn get_output_schemas(&self) -> &Option<Vec<GlueSchema>>

Specifies the data schema for the SparkSQL transform.

pub fn build(self) -> Result<SparkSql, BuildError>

Consumes the builder and constructs a SparkSql. This method will fail if any of the following fields are not set:

• name
• inputs
• sql_query
• sql_aliases

Trait Implementations

impl Clone for SparkSqlBuilder

fn clone(&self) -> SparkSqlBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparkSqlBuilder

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

Formats the value using the given formatter.

impl Default for SparkSqlBuilder

fn default() -> SparkSqlBuilder

Returns the “default value” for a type.

impl PartialEq for SparkSqlBuilder

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