  1. Immutable Records

    XTDB contains a perfect, immutable record of every fact your system has ever known. See the entire history of your business, everywhere.

  2. Temporal Query

    Immutable records are incomplete without time-traveling queries. XTDB allows you to query the entire timeline. Make retroactive corrections, simplify data migrations, and get clarity on out-of-order events.

  3. Relational Query

    It is the interconnection of facts which makes them valuable. Query the relational model with SQL and the graph model with Datalog — over the same data. Explore all your data. Across all implicit relationships, across all time.

  1. Schema-on-Read

    As a document-oriented database, XTDB makes your data immediately available without the need for an upfront schema. Both structured and unstructured data are at home in XTDB.

  2. Eviction

    Legal regulations like GDPR often pose a challenge when designing systems around immutable data. The ability to efficiently evict individual documents is essential for compliance.

  3. Full-Text Search

    Powered by Lucene, XTDB’s full-text search module automatically indexes your entire data set. No custom API necessary. Full-text search queries can be embedded within regular queries.

Using XTDB

Use SQL and Datalog to time-travel and analyze relationships throughout your evolving graph of documents.

  :last-name  "McCarthy"
  :birth-date "04-09-1927"}]

Ethos: Fully Open Source

JUXT holds a fundamental belief that any product we create must be fully open source and XTDB is no exception. We say "fully" because we do not consider "open core" products to be open source. Quality software speaks for itself and does not need to hide behind restrictive licenses.

All software has a lifespan. When closed-source software breathes its last, customers are left stranded. We consider this unethical. Your business should not be forced to accept the risk of closed-source software.
