- A connector implementation does not have to report all the defined metrics. But if a connector reports a metric of the same semantic defined below, the implementation should follow the convention.
- The following metric convention is not a complete list. More conventional metric will be added over time.
- The histogram metrics are usually very expensive. Due to its performance impact, we intentionally excluded them in this FLIP. Please see future work section for more details.

Sink Metrics
Name | Type | Unit | Description |
numBytesOutnumBytesSend | Counter | Bytes | The total number of output bytes since the source started. Count towards the numBytesOut in TaskIOMetricsGroup Predefined, updated by sink implementations. |
numBytesOutPerSecondnumBytesSendPerSecond | Meter | Bytes/Sec | The output bytes per second Predefined, associated with numBytesOutnumBytesSend. |
numRecordsOutnumRecordsSend | Counter | Records | (Existing operator metric) The total number of output records since the source startedThe Sink implementation should reused this existing operator metric instead of creating a new one.sink started Predefined, updated by sink implementations. |
numRecordsOutPerSecondnumRecordsSendPerSecond | Meter | Records/Sec | (Existing operator metric) The output records per secondThe Sink implementation should reused this existing operator metric instead of creating a new one. Predefined, associated with numBytesOutnumBytesSend. |
| numRecordsOutErrorsnumRecordsSendErrors | Counter | Record | The total number of records failed to send Predefined, updated by sink implementations. |
| currentSendTime | Gauge | ms | The time it takes to send the last record. This metric is an instantaneous value recorded for the last processed record. Optional, updated by sink implementations. |
