2 |
Application Lossless and Transparent (ALT) |
Database sessions may be interrupted when a read replica is promoted to primary, a minor version is upgraded, or specifications are changed. Applications need to check session statuses and react to changes by determining: whether a database connection or transaction has been interrupted, how to compensate for transactions, and how to rebuild session contexts. To address these issues, GaussDB(for MySQL) provides ALT, which prevents database connection and transaction interruptions during database system switchovers. There is no need to compensate for transactions or rebuild session contexts, ensuring application continuity. |
