* sketch of broker parallel merges done in small batches on fork join pool * fix non-terminating sequences, auto compute parallelism * adjust benches * adjust benchmarks * now hella more faster, fixed dumb * fix * remove comments * log.info for debug * javadoc * safer block for sequence to yielder conversion * refactor LifecycleForkJoinPool into LifecycleForkJoinPoolProvider which wraps a ForkJoinPool * smooth yield rate adjustment, more logs to help tune * cleanup, less logs * error handling, bug fixes, on by default, more parallel, more tests * remove unused var * comments * timeboundary mergeFn * simplify, more javadoc * formatting * pushdown config * use nanos consistently, move logs back to debug level, bit more javadoc * static terminal result batch * javadoc for nullability of createMergeFn * cleanup * oops * fix race, add docs * spelling, remove todo, add unhandled exception log * cleanup, revert unintended change * another unintended change * review stuff * add ParallelMergeCombiningSequenceBenchmark, fixes * hyper-threading is the enemy * fix initial start delay, lol * parallelism computer now balances partition sizes to partition counts using sqrt of sequence count instead of sequence count by 2 * fix those important style issues with the benchmarks code * lazy sequence creation for benchmarks * more benchmark comments * stable sequence generation time * update defaults to use 100ms target time, 4096 batch size, 16384 initial yield, also update user docs * add jmh thread based benchmarks, cleanup some stuff * oops * style * add spread to jmh thread benchmark start range, more comments to benchmarks parameters and purpose * retool benchmark to allow modeling more typical heterogenous heavy workloads * spelling * fix * refactor benchmarks * formatting * docs * add maxThreadStartDelay parameter to threaded benchmark * why does catch need to be on its own line but else doesnt |
