🔄 GBase Database Internals: Transactions, Logging, and Service Lifecycle Explained

In production systems, executing SQL is only part of the story. Behind every operation in GBase database, there is a full lifecycle: A transaction begins Data changes are written Logs record every step The database service ensures durability Recovery is possible if something fails This article connects transactions + logging + service management into one complete picture. 🧠 Part 1: Transactions — The Foundation of Data Consistency In GBase, all data operations are executed inside transactions. Example: BEGIN; UPDATE users SET age = 30 WHERE id = 1; COMMIT; What happens: Transaction starts Data is modified Logs capture the change Commit finalizes the operation GBase ensures ACID compliance, meaning operations are atomic and recoverable. 🧱 Part 2: Logging — How GBase Tracks Every Change GBase uses logical and physical logs to track database activity. 🔹 Logical Logs Record SQL-level operations Track transactions (INSERT / UPDATE / DELETE) 🔹 Physical Logs Record low-level storage chang
