👉 Rowlock is a concept in computer science, specifically related to multi-user access control systems. In this context, it refers to a situation where two or more users try to simultaneously modify the same data, without any mutual interference. In other words, if one user attempts to change data while another is trying to read that data, the system can't handle both at once because they're interfering with each other's requests. This can lead to inconsistencies in access control and potentially even data corruption or loss.
