"State of XTDB"
summary
XTDB 2.0 ships as an early‑access release with a new query engine, bitemporal range queries (temporal joins and predicates that find when facts first become true), a columnar storage layer built on Apache Arrow columnar storage with bloom filters and metadata for selective reads, and SQL plus Datalog compiling to the same relational plans. Nodes separate storage and compute, checkpointing speeds restarts, and ingest of 10M documents now runs about half the time of recent 1.x builds; feedback and hardening are open.
