ENTRADA

Entrada - A tool for DNS big data analytics

ENTRADA processes DNS data (PCAP-files) from an input location (local, HDFS or S3) and converts and enriches the data to Apache Parquet format, finally sending the results to one of following endpoints:

  • HDFS + Impala (hadoop)
  • S3 + Athena (aws)
  • Local disk (local)

See the database schema for more information about all the database columns.

The data is enriched by adding the following details to each row.

  • Geolocation (Country)
  • Autonomous system (ASN) details
  • Detection of public resolvers (Google, OpenDNS, Quad9 and Cloudflare)
  • TCP round-trip time (RTT)

Apache Impala, AWS Athena or Apache Spark can be used to analyse the generated Parquet data.

ENTRADA handles the required workflow actions such as:

  • Loading and archiving PCAP files
  • Converting and enriching data
  • Creating database schema and tables
  • Creating a S3 bucket
  • Configuring S3 security policy and encryption
  • Creating filesystem directories
  • Moving data files around
  • Uploading data to HDFS or S3
  • Compacting Parquet files on HDFS or S3

For more information see the ENTRADA website.

ENTRADA uses Akka Streams see image below for an overview of the Akka Streams graph created by ENTRADA. ENTRADA Akka Streams flow
