fstrm is an optimized C implementation of Frame Streams that includes a fast, lockless circular queue implementation and exposes library interfaces for setting up a dedicated Frame Streams I/O thread and asynchronously submitting data frames for transport from worker threads. It was originally written to facilitate the addition of high speed binary logging to DNS servers written in C using the dnstap log format.
