Announces Citus 7 with a concrete claim: Postgres extensions now support arbitrary distributed transactions across shards, including savepoints, sequences, joins and nested transactions. Implements a distributed deadlock detector as a background worker that gathers lock tables across nodes and cancels the coordinator transaction to break cycles. Shows parallel index creation and faster bulk loads, demos PGbench with scale 10,000 (~100 GB) on a 4-node cluster to keep data in memory and improve latency, and ships as open source, a managed cloud service, and enterprise software.
