Re: Import error and general questions

Your import error might be related to


Anyway, obviously yes, it's a bug :-). If we can't identify it as an
already-known bug from your description, then we'll probably ask you
for a minimal data set that reproduces the problem (so don't throw
those files out just yet).

But I suspect someone can recognize this as a manifestation of a known
scalability problem; does it ring a bell, anyone? (In fact, I feel
like I ought to recognize it myself, but I don't).

The `strings' table is where all the file contents are stored, so yes,
it will get about as big as the tree you import (the other tables hold
metadata such as directory entries).

So it just gets larger the more data you import. In the
multi-100s-of-megabytes range you're talking about, it shouldn't be a
problem I think.

But hmmm. Don't some systems start having problems when a single file
is in the multi-*gigabyte* range? Or is that only when trying to
access it through stdio? I presume Berkeley DB already has
optimizations for large files, but will check...
