XTDB V2

vs xtdb

  • "Where XTDB has previously been optimized for point-in-time historical queries, v2 now supports ‘cross-time’ queries, e.g. temporal joins and temporal range scans. This unlocks the complete history of data for rich analysis."

Features

Full Bitemporal

  • bitemporal support (point-in-time querying and full bi-Temporal Joins )

    • "Where XTDB has previously been optimized for point-in-time historical queries, v2 now supports ‘cross-time’ queries, e.g. temporal joins and temporal range scans. This unlocks the complete history of data for rich analysis.
    • We support the SQL:2011 standard for bitemporal functionality, and it’s built into the heart of XTQL too."

  • "XTDB 2 will compute and maintain incremental indexes on-the-fly based on the raw data, so index updates will present far less operational impact. This also means the transaction log is now ~ephemeral in the new architecture (no more event-sourcing-style replays required, ever)."
