Interface RowIngestionMeters

All Superinterfaces:
InputStats
All Known Implementing Classes:
NoopRowIngestionMeters, SimpleRowIngestionMeters
public interface RowIngestionMeters extends InputStats
A collection of meters for row ingestion stats, with support for moving average calculations. This can eventually replace SegmentGenerationMetrics, but moving averages for other stats collected by SegmentGenerationMetrics are not currently supported, so we continue to use SegmentGenerationMetrics alongside RowIngestionMeters to avoid unnecessary overhead from maintaining these moving averages.

    • PROCESSED_BYTES

      static final String PROCESSED_BYTES
      Number of bytes read by an ingestion task. Note: processedBytes is a misleading name; this generally measures size when data is initially read or fetched, not when it is processed by the ingest task. It's measuring a stage somewhat earlier in the pipeline. In other words, "processed" and "processedBytes" do not use the same definition of "process". A better name might be "bytesRead" or "inputBytes", although if we change it, we must consider compatibility with existing readers.
