Description
To improve our insight into how much work is being done during bg Fetches, it would be useful to record additional histograms:
- Count of read() calls per couchstore operation (i.e. per open() / close() pair).
- Number of read() calls issued per getMulti() call
- Number of read() calls issues per getMulti() call, per document - i.e. average reads for each document fetched.
Build 5.1.0-1115 contains kv_engine commit ff989f3164424600f39363e00d500b359aa89ec0 with commit message:
