Although, it's possible to do it on the layer above which I do for one of my projects (B+Tree for the Index). @Marc Cunning That’s not possible since you’re asking Tokyo Cabinet to have a different (or split) storage format.

TC binds Value and Index inside only one file, but how to separate them in different files, i.e. "file.tcb - file.idx" meaning: file.tcb containing data values or records only file.idx containing indexes pointing to the values or records in file.tcb.. With this, recovering one broken database could be very easy.. Is possible to create databases with separate INDEX files and DATA files..?

Though you must remember that this obviously reduces throughput. @Mark Callaghan It is crash safe if you tell it to be so. Specifically when you open the database.

And yet, at http://1978th.net/tokyocabinet/spex-en.html#features we see the statement "improves robustness : database file is not corrupted even under catastrophic situation" What does that mean? OK, so Tokyo Cabinet is not crash safe. And yet, at

we see the statement
“improves robustness : database file is not corrupted even under catastrophic situation”
What does that mean?
