Since this implementation of DODB is related to the Crystal language (which isn't fully ported to the OpenBSD plateform at-the-moment), this is a problem.

.SECTION Real-world usage: netlib.re
Netlibre is a service providing free domain names and a website to manage DNS zones.
Domains can be shared and transfered between users, so organizations do not have to rely on a single person.
Resource records are managed with dedicated interfaces, users are helped as much as possible through many automatic zone verifications.
Resource records can be automatically updated via
.I tokens ,
enabling users to host a service despite having a dynamic IP address.
The resource can be updated with a trivial command:
.SOURCE Ruby ps=9 vs=10
wget "https://netlib.re/token-update/<token>"
.SOURCE
.B "The technical parts" .
The service is split into two main components: a user interface (website written in purescript) and a daemon (dnsmanagerd) handling all the server operations.
Several "databases" are maintained
.BULLET Common and RAM-only databases
.BULLET database: users, domains, tokens, connected users (for collaborative work)
.ENDBULLET
Performance-wise, netlibre handles between 2 to 3k req/s with a single core, without any optimization.
Code is written in an almost naive\*[*] way and still performing fine.
.FOOTNOTE1
Keep in mind that netlibre uses poll(2), a very old syscall to handle its event loop (from the 80's!); not newest and way faster event facilities such as epoll(2) and the like.
.FOOTNOTE2
Indexes with file-system representation enables quick debugging sessions and to perform a few basic tasks such as listing all the domains of a user which, in practice, is great to have at our fingertips with simple unix tools.
