Erlang 's support for handling binaries and pattern matching make it a great choice for parsing everything from IPv4 packets, to payloads from the Memcached protocol, SWF files, or databases like Tokyo Cabinet. From a functional programming perspective, there are various ways of building these parsers, taking advantage of the concurrent and recursive nature that is inherent to the language and other challenges which have been gathered while validating the storage & retrieval options for our distributed crawler, and submitting patches to projects like Medici & Tora ( erlang based Tokyo Cabinet clients). The talk will also touch upon Tokyo cabinet's support for mapreduce with Lua, and notes from building your own custom formats & our internal mapreduce'esque and caching frameworks used in building a multi-million impression platform utilizing under a gig of RAM per node.
