Hi Harald,
We explicitly don't want to use some kind of
database system, as the VLR
data needs to be accessed all over the code
directly/synchronously/non-blockingly. We cannot wait for it to be
retrieved from somewhere. That's what is done with HLR data.
Lightning Memory-Mapped Database
(https://en.wikipedia.org/wiki/Lightning_Memory-Mapped_Database) is designed
for exactly these requirements.
It gives non-blocking access to the data - directly in-memory. Yet it also
persists the data to disk in the background. So in case the software is
restarted, it can pick off exactly where it left its dataset.
LMDB is highly recommended.
BR,
Michael A
