Summary:
Now we're able to show more details about a compaction in
GetThreadList() :)
This patch allows GetThreadList() to report basic compaction
operation properties. Basic compaction properties include:
1. job id
2. compaction input / output level
3. compaction property flags (is_manual, is_deletion, .. etc)
4. total input bytes
5. the number of bytes has been read currently.
6. the number of bytes has been written currently.
Flush operation properties will be done in a seperate diff.
Test Plan:
/db_bench --threads=30 --num=1000000 --benchmarks=fillrandom --thread_status_per_interval=1
Sample output of tracking same job:
