Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

filter_predicate: Option<String>

Extra condition clause to filter data from source. For example:

BillingCity='Mountain View'

When using a query instead of a table name, you should validate that the query works with the specified filterPredicate.

partition_column: Option<String>

The name of an integer column that is used for partitioning. This option works only when it's included with lowerBound, upperBound, and numPartitions. This option works the same way as in the Spark SQL JDBC reader.

lower_bound: Option<i64>

The minimum value of partitionColumn that is used to decide partition stride.

upper_bound: Option<i64>

The maximum value of partitionColumn that is used to decide partition stride.

num_partitions: Option<i64>

The number of partitions. This value, along with lowerBound (inclusive) and upperBound (exclusive), form partition strides for generated WHERE clause expressions that are used to split the partitionColumn.

job_bookmark_keys: Option<Vec<String>>

The name of the job bookmark keys on which to sort.

job_bookmark_keys_sort_order: Option<String>

Specifies an ascending or descending sort order.

data_type_mapping: Option<HashMap<JdbcDataType, GlueRecordType>>

Custom data type mapping that builds a mapping from a JDBC data type to an Glue data type. For example, the option "dataTypeMapping":{"FLOAT":"STRING"} maps data fields of JDBC type FLOAT into the Java String type by calling the ResultSet.getString() method of the driver, and uses it to build the Glue record. The ResultSet object is implemented by each driver, so the behavior is specific to the driver you use. Refer to the documentation for your JDBC driver to understand how the driver performs the conversions.

Implementations

impl JdbcConnectorOptions

pub fn filter_predicate(&self) -> Option<&str>

Extra condition clause to filter data from source. For example:

BillingCity='Mountain View'

When using a query instead of a table name, you should validate that the query works with the specified filterPredicate.

pub fn partition_column(&self) -> Option<&str>

The name of an integer column that is used for partitioning. This option works only when it's included with lowerBound, upperBound, and numPartitions. This option works the same way as in the Spark SQL JDBC reader.

pub fn lower_bound(&self) -> Option<i64>

The minimum value of partitionColumn that is used to decide partition stride.

pub fn upper_bound(&self) -> Option<i64>

The maximum value of partitionColumn that is used to decide partition stride.

pub fn num_partitions(&self) -> Option<i64>

The number of partitions. This value, along with lowerBound (inclusive) and upperBound (exclusive), form partition strides for generated WHERE clause expressions that are used to split the partitionColumn.

pub fn job_bookmark_keys(&self) -> &[String]

The name of the job bookmark keys on which to sort.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .job_bookmark_keys.is_none().

pub fn job_bookmark_keys_sort_order(&self) -> Option<&str>

Specifies an ascending or descending sort order.

pub fn data_type_mapping( &self ) -> Option<&HashMap<JdbcDataType, GlueRecordType>>

Custom data type mapping that builds a mapping from a JDBC data type to an Glue data type. For example, the option "dataTypeMapping":{"FLOAT":"STRING"} maps data fields of JDBC type FLOAT into the Java String type by calling the ResultSet.getString() method of the driver, and uses it to build the Glue record. The ResultSet object is implemented by each driver, so the behavior is specific to the driver you use. Refer to the documentation for your JDBC driver to understand how the driver performs the conversions.

impl JdbcConnectorOptions

pub fn builder() -> JdbcConnectorOptionsBuilder

Creates a new builder-style object to manufacture JdbcConnectorOptions.

Trait Implementations

impl Clone for JdbcConnectorOptions

fn clone(&self) -> JdbcConnectorOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JdbcConnectorOptions

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

Formats the value using the given formatter.

impl PartialEq for JdbcConnectorOptions

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

This method tests for self and other values to be equal, and is used by ==.

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

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