Application: Memory-frugal index design in storage engine (Patent ID: US20240061823A1)
The patent filed by Alibaba Group Holding Ltd. describes a storage engine that utilizes different formats for index fragments and index entries based on the properties of records to reduce memory space usage while maintaining search efficiency. By employing various formats for index fragments covering records with different properties, the storage engine can create, maintain, and update index mappings for functionalities like point-lookup, range query, record deletion, and addition. The method involves detecting a triggering event, determining record properties, and converting index fragments to new formats with reduced memory usage based on these properties.
The triggering event for examining index fragments can include garbage collection operations, regular maintenance tasks, or user instructions. Record properties considered for format conversion include logical sizes, sector spans, and continuity of keys within the index fragment. The method also involves selecting the new format from predefined options, each with distinct header and entry formats. Additionally, the patent covers actions such as storing new records, creating corresponding index entries, and managing record deletions within the storage device. Overall, the patent aims to optimize memory usage in storing index fragments while ensuring efficient record retrieval and management operations within the storage engine.
