I want to use spark jdbc to access alibaba cloud hologres (https://www.alibabacloud.com/product/hologres) internal hidden column `hg_binlog_timestamp_us ` but met the following error:
Exception in thread "main" org.apache.spark.sql.AnalysisException: cannot resolve 'hg_binlog_timestamp_us' given input columns: [top_trans_order.acc_split_bunch, top_trans_order.acct_code, ...]; line 4 pos 30; So, my question is how to access the internal hidden columns of table by spark jdbc (sql and DataFrame) ? Thanks!
