Orioledb is a cloud-native storage engine for PostgreSQL designed to replace the default storage layer to improve vertical scalability and performance on modern hardware. It functions as an index-organized table store, organizing table rows directly within the primary index to accelerate data retrieval. The engine utilizes an undo log storage system to manage data versioning, which eliminates the need for manual vacuuming and prevents table bloat. It further reduces the disk footprint through block-level and page-level data compression. The project provides capabilities for advanced index ma
Minimizes disk operations during write transactions through the use of logical and non-persistent undo logs.
