Description:

Frame Streams is a light weight, binary clean protocol that allows for
the transport of arbitrarily encoded data payload sequences with
minimal framing overhead - just four bytes per data frame. Frame
Streams does not specify an encoding format for data frames and can be
used with any data serialization format that produces byte sequences,
such as Protocol Buffers, XML, JSON, MessagePack, YAML, etc.

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.
