I loath to make an announcement. I am a long time lurker but thought this might be of interest to some.
nytimes.com has developed a piece of middleware - dbslayer - that sits between your mysql databases and applications. It takes http requests and returns mysql results encapsulated in JSON w/ a few additional features. It makes extensive use of apr - threads, sockets, queues, memory pools, etc. We use it in a high traffic production environment and have recently open sourced it - http://code.nytimes.com/projects/dbslayer - the feature set is expected to grow but even it's current state we have found it very useful. Thanks to APR for such a great abstraction layer, most of the core code was created in a very short time and we have only run into one odd issue (portfs on solaris inside apr_pollset_poll). thanks, derek
