Xapian discuss - Nov 2013 - Question about embedding Xapian index in one file

Hi,

Xapian uses a directory as standard storage backend. Is that possible to
pack everything in a file (a tar file for example), and to tell
libxapian to open it (by telling him at which offset are the different
stuff)?

If this is not possible yet, would that be technically possible to
implement such a feature? How complex would that be?

Kind regards
Emmanuel

Hi,

!!!Warning: Xapian-Newbie writing

1.) a possible solution: I would not do this by xapian, but by the
operating system. You could create a "moutable file", and mount it to
a
directory of your choice and let Xapian read and write in this
directory. All changes would happen in this one file.

2.) just for clarification: why would you want such thing? What is the
advantage of this plan?

Best

Wilm

This is not really on option for us, our software supports a lot of
different OSes, and I don't really want to start to add such type of
complexity.

We provide read-only archives of content in a dedicated file and we use
Xapian only to provide full-text search. Not having everything in one
file makes the life of our users (and ours) unnecessary complicated.
