Hello all,
As I said when I introduced my Storm profiling project, I have a few
questions that I hope you can help me answer.
The first of these is one of naming. As they say, only two things are
really hard in software: cache invalidation and naming things. Since
I'm messing with both, I'd at least like to get the naming right. :-)
Is there some agreed term for the process of reading an object from the
database into the cache, when it wasn't in the cache before? I know of
several terms already, but they all had drawbacks so I provisionally
added one of my own. The terms I know of are:
"Cache." But that can mean either the action or bringing an object into
the cache, or the status of keeping something in cache. I need
something that very clearly has only the former meaning.
"Deserialize." It's a bit close to the mechanics of one part of the
work, where I'd prefer something slightly more abstract that also covers
the process of transferring the data from the database.
"Load." This term has lots of uses already, so it could be a bit vague.
Moreover, I'm worried that if I say an object gets "loaded," a reader
might think that at that point the object might actually already be in
cache. And I could easily be wrong.
"Load into memory" or "Load into cache." Good, but wordy!
For now I went with "fetch," which is an established term for a similar
action in processor architecture. It also combines naturally into
"prefetching," which is a special kind of fetching.
Does anybody have any suggestions, opinions, solutions? It may seem
strange that I attach so much importance to one verb, but it pops up in
all sorts of ways: fetch contexts, fetch profiles, fetch statistics,
fetch callback functions, and so on.
