Summary: Changes: * improves monitoring by displaying average size of a Put value and average scan length * forces the minimum value size to be 10. Before this it was 0 if you didn't set the distribution parameters. * uses reasonable defaults for the distribution parameters that determine value size and scan length * includes seeks in "reads ... found" message, before this they were missing Test Plan: Before this change: ./db_bench --benchmarks=fillseq,mixgraph --mix_get_ratio=50 --mix_put_ratio=25 --mix_seek_ratio=25 --num=100000 --value_k=0.2615 --value_sigma=25.45 --iter_k=2.517 --iter_sigma=14.236 fillseq : 4.289 micros/op 233138 ops/sec; 25.8 MB/s mixgraph : 18.461 micros/op 54166 ops/sec; 755.0 MB/s ( Gets:50164 Puts:24919 Seek:24917 of 50164 in 75081 found) After this change: ./db_bench --benchmarks=fillseq,mixgraph --mix_get_ratio=50 --mix_put_ratio=25 --mix_seek_ratio=25 --num=100000 --value_k=0.2615 --value_sigma=25.45 --iter_k=2.517 --iter_sigma=14.236 fillseq : 3.974 micros/op 251553 ops/sec; 27.8 MB/s mixgraph : 16.722 micros/op 59795 ops/sec; 833.5 MB/s ( Gets:50164 Puts:24919 Seek:24917, reads 75081 in 75081 found, avg size: 36.0 value, 504.9 scan) Reviewers: Subscribers: Tasks: Tags:
