Abstract: A method for optimizing memory access for database operations is provided. The method may include performing a database operation by at least executing a first instruction stream associated with the first database operation. The first database operation may be defined as a coroutine to at least enable the execution of the first instruction stream to be interleaved with an execution of a second instruction stream. In response to determining that data required to continue the execution of the first instruction stream is absent from a cache, the execution of the first instruction may be suspended and the second instruction stream may be executed instead. Related systems and articles of manufacture, including computer program products, are also provided.

Abstract: A method for optimizing memory access for database operations is provided. The method may include identifying an access pattern associated with a database operation. The access pattern may include data required to perform the database operation. One or more memory pages may be generated based at least on the access pattern. The one or more memory pages may include at least a portion of the data required to perform the database operation. The one or more memory pages including at least the portion of the data required to perform the database operation may be stored in a main memory. The database operation may be performed by at least loading, from the main memory and into a cache, the one or more memory pages including at least the portion of the data required to perform the database operation. Related systems and articles of manufacture, including computer program products, are also provided.
