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
