Description

当有多个sink并且表名相同(table_name)的时候, 统计数据中sinkwritecount会重复计算, 比如sink一个是kafka一个是es,一个是mysql, 表名相同的情况下,source读到1条数据, 那么sinkwritecount中就会是 table_name:2, database.table_name:1, 如何把每个sink区分开呢?

Usage Scenario

对存储的数据进行统计

Contributor guide

Research direction
Investigate how sink write count metric aggregates when multiple sinks have identical table names. Trace the metric recording code in the sink and metric service to identify the point where table name is used as the key without considering sink identity.
