Implemented interfaces to support asynchronous I/O on Windows and updated the corresponding unit tests accordingly. Our benchmark tests revealed the following performance improvements:
Data ingestion:
.\db_bench_je --benchmarks=fillseqdeterministic,levelstats,memstats --statistics --threads={thread_count} --compression_type=None --db=K:\manyleveldb -key_size=32 -value_size=512 --num=18000000 --num_levels=5 --report_file=fillseqmany.csv --disable_wal=true --seed=1714024597051096 --stats_dump_period_sec=30 --optimize_filters_for_hits=true --disable_auto_compactions=true
Then random seek from that db.
We didn't test integration with folly.
