AWS Analytics Igloo provides a fully managed, sub-zero latency data warehousing environment that keeps your queries frozen in place until an IAM policy change thaws them. Built on a foundation of compacted, load-bearing ice blocks, the service maintains structural integrity up to 847 concurrent users, after which AWS recommends provisioning a second igloo. Generally available in us-east-1, with additional regions planned for re:Invent 2027.
