pub struct UntypedSourceHandle { /* private fields */ }Expand description
Untyped handle for pushing raw RecordBatch data.
Implementations§
Source§impl UntypedSourceHandle
impl UntypedSourceHandle
Sourcepub fn push_arrow(&self, batch: RecordBatch) -> Result<(), StreamingError>
pub fn push_arrow(&self, batch: RecordBatch) -> Result<(), StreamingError>
Push a RecordBatch.
The batch is sent to the SPSC channel for pipeline processing and
also buffered for ad-hoc SELECT snapshot queries.
§Errors
Returns StreamingError if the channel is full or closed.
Sourcepub fn current_watermark(&self) -> i64
pub fn current_watermark(&self) -> i64
Get current watermark.
Sourcepub fn is_backpressured(&self) -> bool
pub fn is_backpressured(&self) -> bool
Whether the source buffer is experiencing backpressure (>80% full).
Sourcepub fn max_out_of_orderness(&self) -> Option<Duration>
pub fn max_out_of_orderness(&self) -> Option<Duration>
Get the maximum out-of-orderness duration, if configured.
Sourcepub fn set_event_time_column(&self, column: &str)
pub fn set_event_time_column(&self, column: &str)
Declare which column in the source data represents event time.
When set, source.watermark() enables late-row filtering
without a SQL WATERMARK FOR clause.
