libanyevent-dbi-perl - 3.04-1 main

AnyEvent::DBI is an AnyEvent extension, you need to make sure that you use
and run a supported event loop. This module implements asynchronous DBI access
by forking or executing separate "DBI-Server" processes and sending them
requests. It means that you can run DBI requests in parallel to other tasks.
The overhead for very simple statements ("select 0") is somewhere around 100%
to 120% (dual/single core CPU) compared to an explicit
prepare_cached/execute/fetchrow_arrayref/finish combination.
