Understanding the Problem: Two Tables with Real-time Data Updates Overview of the Challenge The problem presents two tables, Table_A and Table_B, with identical structures. Table_A is updated daily, while Table_B is updated in real-time. The goal is to determine if the counter values in both tables are the same and, if not, identify which columns have discrepancies. Additionally, we need to keep track of how many days the values have been misaligned.
