Object access read/write time

[Jeremy Raymond]

Hello,

I'm looking for a way to tell the last time an object was read exclusive to the last time it was written. I see that OBJECT IDLETIME gives me time since the object either written or read. Is there a way to distinguish last read time vs last write time?

Not without a patch, as far as I know. I wouldn't put particularly
good odds on it being accepted if a patch were submitted, but I may be
wrong.

Why is that?

[Josiah Carlson]

Since you didn't ask precisely, I'll answer both possible
interpretations of the question.

It requires a patch, because the information is not currently available.

I would give it low odds for one major reason. The information is not
currently available, and making it available would induce overhead on
every key for a use that isn't necessary for the vast majority of
use-cases (which is why it isn't currently available). In the best
case, it would increase overhead by 4 or 8 bytes per key, depending on
the platform. Maybe not so much a big deal with 1 million keys, but
100 million keys makes the overhead significant.
