I tried to merge them, but the assumptions of working on unsafe code were
very difficult to remove. I also had a difficult time figuring out a useful API.
Happy to look at specific suggestions, but the way that the existing
implementation always iterates through unsafe pointers meant that there is
likely to be nearly no shared code. Merging by simply moving my methods to the
existing implementation is certainly doable.

> Project: Apache Drill
> Issue Type: New Feature
> Reporter: Ted Dunning
>
> PCAP files [1] are the de facto standard for storing network capture data. In
> security and protocol applications, it is very common to want to extract
> particular packets from a capture for further analysis.
> At a first level, it is desirable to query and filter by source and
> destination IP and port or by protocol. Beyond that, however, it would be
> very useful to be able to group packets by TCP session and eventually to look
> at packet contents. For now, however, the most critical requirement is that
> we should be able to scan captures at very high speed.
> I previously wrote a (kind of working) proof of concept for a PCAP decoder
> that did lazy deserialization and could traverse hundreds of MB of PCAP data
> per second per core. This compares to roughly 2-3 MB/s for widely available
> Apache-compatible open source PCAP decoders.
> This JIRA covers the integration and extension of that proof of concept as a
> Drill file format.
