Abstract: In some implementations, a storage node receives data processing instructions from a compute node of a network architecture. The storage node detects a Directed Acyclic Graph (DAG) within the data processing instructions. The DAG includes a plurality of data processing operations arranged within the DAG according to an execution. The data processing operations further include user-defined function (UDF) information associated with a UDF. The storage node may retrieve a first data object from an object store of the distributed storage node based on object keys information within the plurality of data processing operations. The storage node may execute the plurality of data processing operations using the retrieved first data object to generate a DAG execution result, the executing of the plurality of data processing operations based on the execution order. The storage node may communicate the DAG execution result to the compute node in response to the data processing instructions.

Abstract: A computer implemented method comprises accessing data stored in memory of the computer system, wherein the memory includes a faster access storage medium and a slower access storage medium; determining respective exponential moving averages of a number of access operations performed on respective memory locations of the memory; and transferring a portion of the data into the faster access storage medium and transferring a portion of the data into the slower access storage medium according to the determined exponential moving average.
