Struct DeltaSourceConfig 

pub struct DeltaSourceConfig {
    pub connection: DeltaConnection,
    pub version: Option<u64>,
    pub timestamp: Option<String>,
    pub columns: Vec<String>,
    pub batch_size: usize,
}

Configuration for the Delta Lake source connector.

The table_uri / credentials / storage_options keys are flattened in from the shared DeltaConnection. Reads scan the table’s active data files at the latest version (or a pinned version / timestamp for time travel) and yield each row as a JSON object.

Fields

connection: DeltaConnection

Table location + object-store credentials.

version: Option<u64>

Time travel: read the table as of this version. Mutually exclusive with timestamp.

timestamp: Option<String>

Time travel: read the table as of this RFC 3339 timestamp. Mutually exclusive with version.

columns: Vec<String>

Projection pushdown: only read these columns. Empty = all columns.

batch_size: usize

Page size hint for stream_pages. Governs how many rows accumulate before a StreamPage is emitted; the underlying parquet row-group size still bounds each read. 0 is the “no batching” sentinel — one page per file.

Implementations

impl DeltaSourceConfig

pub fn new(table_uri: impl Into<String>) -> Self

Build a source config for table_uri with defaults.

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

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

Trait Implementations

impl Clone for DeltaSourceConfig

fn clone(&self) -> DeltaSourceConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeltaSourceConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DeltaSourceConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for DeltaSourceConfig

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 DeltaSourceConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
