The elements of "filters" all process a copy of the input row, and the results are pooled, sorted, and combined into a single output row. If multiple cells are produced with the same column and timestamp, they will all appear in the output row in an unspecified mutual order. Consider the following example, with three filters: input row | ----------------------------------------------------- | | | f(0) f(1) f(2) | | | 1: foo,bar,10,x foo,bar,10,z far,bar,7,a 2: foo,blah,11,z far,blah,5,x far,blah,5,x | | | ----------------------------------------------------- | 1: foo,bar,10,z // could have switched with #2 2: foo,bar,10,x // could have switched with #1 3: foo,blah,11,z 4: far,bar,7,a 5: far,blah,5,x // identical to #6 6: far,blah,5,x // identical to #5 All interleaved filters are executed atomically.
