Parallel database page flushing

Abstract:

Physical block numbers are assigned to pages loaded into memory of an in-memory database. Thereafter, pages having a same size are distributed to one of a plurality of helper threads executing in parallel for processing if such pages having consecutive physical block numbers. Each of these helper threads can have a corresponding small page buffer. Contents of the respective small page buffers are later flushed to physical disk persistence when such small page buffers are full.
