Guoliang Sun commented on KYLIN-6019:
-------------------------------------
h3. Dev Design
Add the calculation for `scanRows` and `scanBytes` for the corresponding
operators, including `HiveTableScanExecTransformer`, `BatchScanExec`, and
`BatchScanExecTransformer`.
> The metrics data for the number of scanned rows in pushdown queries is lost

> Key: KYLIN-6019
> URL: https://issues.apache.org/jira/browse/KYLIN-6019
> Project: Kylin
> Issue Type: Bug
> Affects Versions: 5.0.0
> Reporter: Guoliang Sun
> Priority: Major
>
> h3. Root Cause
> The operator types for scanning data contained in the generated SparkPlan are
> not fully covered when calculating `scanRows` and `scanBytes`. In the current
> case, this is due to the lack of accumulation of metrics for
> `HiveTableScanExecTransformer`.
