Before they are applied to the actual data files, it is a mechanism for reliably and sequentially recording database changes. The ACID (Atomicity, Consistency, Isolation, Durability) properties of a database […]

They manage replication lag, prevent replicas from becoming overloaded, guarantee dependable data delivery from the primary to replicas, and […]
