In a computing device supporting distributed stream processing, a request is received from a controller device to redistribute blocks storing streamed data. The request indicates that a number of blocks stored on the computing device be sent to a second computing device. The controller device controls distribution of analytic results to a data access system. The analytic results are computed from the streamed data. The indicated number of blocks are selected from the blocks storing the streamed data. The selected blocks are sent to the second computing device. Pointers to remaining blocks of the blocks storing the streamed data are updated.
