A network flow(netflow) data processing toolkit. Using Apache Spark write netflow data to elastic server or parquet files that can be queried and analyzed.
Analyzing job system, REST API query Flow netflow data from data file, and write results to MongoDB
Experiment data from the website https://traces.simpleweb.org/traces/netflow/netflow1/

Transforming netflow(v5) pcap file to netflow data row, and write it to elastic search or parquet file. Command usage

Elastic server address setting in application.properties
- With writing netflow data to elastic server, you can query the network packet flow in real time For example, query the packets ip address "122.166.26.132" sent out.

...Compute max dataflow(socket size) between two ip's on elastic search by Spark plugin provided by elastic, but it is too slow, it's about orders of magnitude slower than computation on parquet data file.

--driver-cores 1 --executor-cores 2 --master spark://hxm-desktop:7077 /opt/Earlgrey/jobs/target/earlgrey-jobs-0.4.jar -print 10After testing with writing/reading netflow data to Elastic by Spark, I found it was too slow. And I just took a peek at source code of Elastic-Spark-connector, it seems like just wrapping some REST API. It's totally un-workable analyse data with Spark on elastic.
I have modified code to writing and reading to HBase, it seems good. It took about 5 minutes write 20 million record with my 2 pc over network. And class Active Flow found 2 most mass traffic ip spent about 1.x minutes also running local spark and HBase on another pc.

- Query flow from HBase with or without HBase Filter
After some research on Elastic data saving from Spark, I found bottlenecks are in Elastic io, it should be Elastic indexing. That should be the problem that cannot be solved, because Elastic using Lucene, that a space change time solution, indexing is the must step. Query specific flow from HBase's row key, then it tooks a bout 1.x second totally spark-job, that means quickly. If searching use HBase filter, it took about 1x seconds. Searching from Spark, it took 2x seconds.
