Described herein is a system and method for coded streaming data to facilitate recovery from failed or slow processor(s). A batch of processing stream data can be partitioned into a plurality of data chunks. Parity chunk(s) for the plurality of data chunks. The plurality of data chunks and the parity chunk(s) can be provided to processors for processing. Processed data of at least some (e.g., one or more) of the plurality of data chunks, and, processed data of parity chunk(s) are received. When it is determined that processed data for a pre-defined quantity of data chunks has not been received by a pre-defined period of time, the processed data for particular data chunk(s) of particular processor(s) from which processed data has not been received are determined based, at least in part, upon the received processed parity chunk(s) and the received processed data chunk(s).

Coded stream processing

Described herein is a system and method for a static streaming job startup sequence. During compilation of a streaming job, a graph of computing nodes of the streaming job is traversed to determine a minimum start time of computing node(s) downstream of each input computing node of the streaming job. Also, during compilation, a start time is assigned to each input computing node in accordance with the determined minimum start time. During execution of the streaming job, responsive to receipt of the trigger anchor by a particular input node, processing of the particular input computing node using the determined minimum start time is commenced. The input computing node further generates an anchor. Input data is received, and, a batch of data provided in accordance with the received input data and generated anchor.
