US Patent 11249916 Single producer single consumer buffering in database systems

A method for execution by a virtual machine core includes retrieving a first pointer by accessing a first buffer of a plurality of buffers stored in allocated memory of a main memory based on assignment of the virtual machine core as a single consumer of the first buffer. First intermediate data in the allocated memory is accessed by utilizing the first pointer. Second intermediate data is generated by executing one of an ordered set of operations on the first intermediate data. The second intermediate data is written to the allocated memory. A second pointer is written to a second buffer of the plurality of buffers based on assignment of the virtual machine core as a single producer of the second buffer.
