An embodiment of the invention includes a processor can identify one or more simple patterns in at least one data stream of the data streams. The simple pattern can include repetition of a data object of the data objects. The processor can also identify one or more multi-patterns in at least one data stream of the data streams, wherein the multi-pattern can include repetition of a data block. The data block can include at least two contiguous data objects that are in the same order in the data block. The processor can identify one or more composite patterns in at least two data streams of the data streams, wherein the composite pattern can include data objects on each of the at least two data streams that repeat together in the same pattern.
