Title: To Distribute, To Drop, Or To Divide, That Is The Question In Adaptive Stream Processing

The increasing need for real-time data processing has triggered the rapid evolution of distributed Stream Processing Engines (dSPEs). In a dSPE, data are processed as soon as they become available and queries execute continuously. Low operational cost and timely processing can become a challenge for a dSPE, considering the volatile and uncharted nature of input streams. This calls for adaptable dSPEs, which can react to fluctuations in processing demands. In this talk, I will present work done on dSPEs’ adaptability, focusing on the techniques of stream partitioning, load shedding, and dSPE elasticity.
