A system and method for executing input/output (I/O) tasks for clients in a distributed computing system. One or more I/O requests made by a client are received. The operation instructions for the request data in the I/O requests are separated from the request data. A data representation called data label (or label) is created for executing operation instructions of the I/O requests. A data label corresponds to each of the I/O request and includes a unique identifier, information to the source and/or destination for the request data, and an operation instruction separated from the request data. The data label is pushed into a distributed label queue and is dispatched to an individual worker node according to a scheduling policy. The worker node executes the I/O tasks by executing the dispatched data label. The system and method can execute I/O tasks independently and decoupled from the client applications.
