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, using an offset pointer to manage data writing continuity. When the memory arena reaches a predefined usage threshold, data is flushed to storage, ensuring contiguous data storage space. The usage threshold can be based on available space percentage or data quantity in the memory arena, with additional operations including handling write requests, allocating new memory arenas if space is insufficient, and searching for data objects in the memory arena before storage.
Furthermore, the patent covers a server hosting multiple regions for a distributed computing system, with instructions stored in the server's memory to track memory arena usage, determine usage thresholds, and flush data to storage. The method ensures data writing continuity and efficient memory management by resetting the offset pointer and allocating new memory arenas when needed. Additional instructions cover handling write requests, incrementing the offset pointer, and ensuring sufficient space in the memory arena before storing data objects. The patent also includes a non-transitory machine-readable storage medium with instructions for the server to perform the same operations, emphasizing the importance of efficient memory management and data storage in distributed computing systems.
