This cuts our per element processing overhead significantly down. For example in the ProcessBundleBenchmark.testLargeBundle we saw a reduction of about half of the execution state management overhead for each element (10.6% to 5.6% CPU overhead per element). Before:  After:  The benchmark reflects this with a nice 11.5% performance improvement. Before: ``` Result "org.apache.beam.fn.harness.jmh.ProcessBundleBenchmark.testLargeBundle": 3265.141 ±(99.9%) 238.744 ops/s [Average] (min, avg, max) = (2952.616, 3265.141, 3525.482), stdev = 223.321 CI (99.9%): [3026.398, 3503.885] (assumes normal distribution) ``` After: ``` Result "org.apache.beam.fn.harness.jmh.ProcessBundleBenchmark.testLargeBundle": 3642.512 ±(99.9%) 45.865 ops/s [Average] (min, avg, max) = (3582.394, 3642.512, 3713.820), stdev = 42.902 CI (99.9%): [3596.647, 3688.377] (assumes normal distribution) ``` This is towards #21250 ------------------------ Thank you for your contribution!
