 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.

 .SECTION Conclusion
 The
 .I common
 database should be an acceptable choice for most applications.
+
+.BULLET talk about netlib.re
+.BULLET triggers are available and can be adapted to do anything, indexes are a simple use of triggers
+.BULLET common db is great for most applications
+.BULLET indexes can provide a view of the current state of the database
+.BULLET ramdb is a great tool, same API than the rest so you can attach indexes to it
