Struct RedshiftSourceConfig 

pub struct RedshiftSourceConfig {
    pub connection: RedshiftConnection,
    pub query: String,
    pub params: Vec<Value>,
    pub max_connections: u32,
    pub batch_size: usize,
    pub replication: RedshiftReplication,
    pub state_key: Option<String>,
}

Configuration for the Amazon Redshift query source.

Fields

connection: RedshiftConnection

Connection block (host / port / database / user / credentials / tls), flattened to the config top level.

query: String

SQL query to execute. May contain ${field.path} parent-context tokens (resolved to positional binds at runtime) and, for incremental replication, a ${bookmark} token.

params: Vec<Value>

Positional bind parameters for the query, applied in $1, $2, … order before any context- or bookmark-derived values. Defaults to empty.

max_connections: u32

Maximum number of connections in the pool. Defaults to 10.

batch_size: usize

Records per emitted StreamPage. Rows are drained from the sqlx cursor and yielded whenever the buffer reaches this size. Defaults to DEFAULT_BATCH_SIZE.

batch_size = 0 is the “no batching” sentinel: the cursor is fully drained and the entire result set is emitted in a single page.

replication: RedshiftReplication

Replication mode. Defaults to RedshiftReplication::Full.

state_key: Option<String>

Explicit state-store key for the incremental bookmark. When unset, a key is derived from the host / database and a query fingerprint.

Implementations

impl RedshiftSourceConfig

pub fn validate(&self) -> Result<(), FaucetError>

Validate the config; returns a human-readable error if invalid.

Trait Implementations

impl Clone for RedshiftSourceConfig

fn clone(&self) -> RedshiftSourceConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RedshiftSourceConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RedshiftSourceConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for RedshiftSourceConfig

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for RedshiftSourceConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
