Cool. I think there’s general agreement that doing this in as small bites as possible is going to be the best approach. I have no interest in mega patches.

I agree. This is why I like the idea of proactively working to improve the readability of the codebase as a specific goal, rather than being wrapped into some other unrelated patch. Keeping the scope in check is the challenge. Simple class and method renames, as several have pointed out, is easy enough with IDEA. I’ll start with class renames, as individual patches for each of them. I’ll be sure to call it out on the ML. First one will be ColumnFamilyStore -> TableStore.
