We currently have a preliminary idea: data verification actually consists of two parts—data quality verification and data consistency verification. Data quality verification: A plugin can be additionally integrated in the transform phase to verify whether the data written into and output from the transform process are consistent. <img width="1270" height="1089" alt="Image" src="https://github.com/user-attachments/assets/0318a0ad-cb3d-4fe7-a4ad-29a4a1be4474"; /> Data consistency verification: To avoid secondary queries, we collect digests/samples separately from the source reading path and the sink writing path, then perform indicator-level/row-level reconciliation in the verification zone (including row count, PK coverage, field digests, sample row comparison, and diff output). <img width="854" height="1243" alt="Image" src="https://github.com/user-attachments/assets/2d880e63-c00e-45ad-9464-b4a294284ae9"; /> -- This is an automated message from the Apache Git Service.
