Data reduction methods, systems, and devices

A system comprising:

• network device configured receive a plurality of data values, wherein the plurality of data values includes a plurality of data units, and wherein the plurality of data values are received as streamed data;
• a data analyzer configured to:
• determine a test statistic based on at least some of the plurality of data units, the test statistic characterizing a data pattern that is represented by a degree of difference between a first data unit of the plurality of data units and at least a second data unit of the plurality of data units, the second data unit being received before the first data unit;
• and
• include the first data unit in a first data block in response to a determination that the test statistic indicates a data pattern with a low degree of difference, the determination being based on a comparison with a designated difference threshold, the first data block being a same data block as a second data block that includes the second data unit.

A method comprising:

• receiving a plurality of data values, wherein the plurality of data values includes a plurality of data units arranged as a plurality of data blocks;
• determining, using a data analyzer, a test statistic based on at least some of the plurality of data units, the test statistic characterizing a data pattern that is represented by a degree of difference between a first data unit of the plurality of data units and at least a second data unit of the plurality of data units, the second data unit being received before the first data unit;
• and
• including, using the data analyzer, the first data unit in a first data block in response to determining that the test statistic indicates a data pattern with a low degree of difference, the determining being based on a comparison with a designated difference threshold, the first data block being a same data block as a second data block that includes the second data unit.
