From Zero to Self-Built Oracle Transaction Log Analytics Engine: How TLA Breaks the Performance Shackles of LogMiner, XStream, and OGG

From Zero to Self-Built Oracle Transaction Log Analytics Engine: How TLA Breaks the Performance Shackles of LogMiner, XStream, and OGG Foreword In the realm of database CDC (Change Data Capture), parsing Oracle transaction logs has always been a persistent challenge. LogMiner is free but painfully slow. XStream performs decently but requires a GoldenGate license. OGG is powerful yet expensive, with lagging support for domestic database environments in China. As for local CDC solutions, some rely on ROWID-based implementations that introduce data inconsistency risks, while others require insert
