Andréas,
Thanks for creating a GitLab account and following up on our paperwork.
I can see your MR for the tdb_find patches, but it would be awesome if
you could raise one for the LDB in-memory-TDB change also. 

In the meantime Douglas is running a performance test on our test
server to confirm things, but it would be great to move this along so
our users can benefit.

Make sure to include your Signed-off-by and
