Poseidon is a distributed log search platform from Qihoo 360 that builds inverted indexes over Hadoop/HDFS-stored logs and serves sub-second string searches across hundreds of trillions of records. It consists of Map/Reduce index builders plus Go-based HTTP microservices (searcher, proxy, meta, idgenerator, hdfsreader).

Use cases

  • search trillions of log lines in seconds
  • query historical logs for security incident investigation
  • track APT threat activity across massive log archives
  • full-text search over HDFS data without duplicating storage
  • build inverted indexes with Hadoop Map/Reduce jobs
  • search petabyte-scale structured or unstructured data

When to choose

  • you already run a Hadoop/HDFS cluster with massive log data
  • you need fast string retrieval over historical logs for security forensics
  • you want search without moving data out of Hadoop storage

When to avoid

  • you need a general-purpose document search engine with real-time indexing
  • you don't operate Hadoop infrastructure
  • you need actively maintained software with recent releases
  • your dataset is small enough for Elasticsearch or similar
