Legend: | |
* wps = writes/second, readwhilewriting had a rate limit on the writer, thus write rates match | |
* ingest - GB of data written into RocksDB | |
* flush - GB of memtable flushes | |
* compact - GB of compaction | |
* c.wsecs - wall clock seconds of compaction, from "Comp(sec)" column in compaction IO stats | |
* c.csecs - CPU seconds of compaction, from "CompMergeCPU(sec)" column in compaction IO stats | |
* cpu/w - c.csecs / wps | |
* stall% - percentage of time writes are stopped or stalled | |
* ml2comp - level at which compression starts, levels above this are not compressed | |
* avg-sec-compaction-job - average time for a compaction/flush job into this level, "Avg(sec)" column from compaction IO stats | |
