Memory allocation buffer to reduce heap fragmentation in servers
A recently granted patent (Publication Number: US11899937B2) discloses a method for operating a region server in a distributed computing system. The method involves tracking memory arena usage in the server's memory heap dedicated to a specific region. An offset pointer is utilized to track the previous end location for data writing, and data is flushed to storage when the memory arena reaches a specified usage threshold. The memory arena is a contiguous portion of the memory heap, ensuring that freed data storage space is also contiguous. The method includes handling write requests from clients, storing data objects in the memory arena, and allocating additional memory arenas if space is insufficient. The system is designed for non-relational, distributed databases, such as an HBase cluster, and can efficiently manage multiple regions hosted on the server.
Furthermore, the patent also covers a server hosting multiple regions for a distributed computing system, with instructions stored in the server's memory to perform the described operations. The server tracks memory arena usage, flushes data to storage based on usage thresholds, and handles write requests from clients. The instructions include incrementing offset pointers, ensuring sufficient space before storing data objects, and managing multiple memory arenas for different regions. Additionally, a non-transitory machine-readable storage medium is disclosed, containing instructions for a server to track memory arena usage, flush data to storage, and handle write requests efficiently. The medium includes instructions for determining usage thresholds based on available space or data quantity, storing data objects in dedicated memory arenas, and ensuring sufficient space before storage. Overall, the patent details a comprehensive method for optimizing memory usage and data storage in a distributed computing environment.
