             Summary: Want a memory format for PCAP files
                 Key: DRILL-5432
                 URL: https://issues.apache.org/jira/browse/DRILL-5432
             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.
