Struct CompiledStreamingQuery 

Source 
pub struct CompiledStreamingQuery {
    pub query: StreamingQuery,
    pub source_plan: LogicalPlan,
    pub input_schema: Arc<RowSchema>,
    pub output_schema: Arc<RowSchema>,
    pub metadata: QueryMetadata,
}
Expand description

Result of successful compilation — ready for execution.

Fields§

§query: StreamingQuery

The compiled StreamingQuery, in Ready state. Call .start() before use.

§source_plan: LogicalPlan

[LogicalPlan] containing only the source scan (TableScan/EmptyRelation). The caller executes this via DataFusion to get the input record batch stream.

§input_schema: Arc<RowSchema>

Input RowSchema for RecordBatch → EventRow conversion.

§output_schema: Arc<RowSchema>

Output RowSchema (may differ from input if projection changes columns).

§metadata: QueryMetadata

Compilation metadata for diagnostics.
