Cold, Warm & Hot Data

Historical, queryable, and live — three ways to get your data out.

Once data lands through a Connection or API node, you can pull it back out three ways: download the history, query what's flowing now, or stream it live.

The three tiers

Cold, Warm, and Hot.

TierWhat it's forStatus
ColdHistorical data, downloaded on demandAvailable
WarmAd-hoc and saved queries against flowing dataAvailable
HotLive, near-real-time updates as data arrivesAvailable
Cold data

Download your history.

Request a historical export for a connection or an entire surface, with an optional date range. Useful for offline analysis, backfills, and audits.

Warm queries

A custom query endpoint for data in motion.

Warm Query gives you a dedicated endpoint for querying data as it's being processed — run one-off queries, or save a named query you (or Azi) can re-run and reference elsewhere. Query authoring is Azi-assisted: describe what you want in plain language and Azi drafts the query for you to review.

Roadmap
  • Referencing flow-node context directly inside a query
  • Deeper cross-workspace query management
Hot data

Near-real-time, as it happens.

Subscribe to a live stream of incoming device/system activity, or a change feed that fires every time your workspace configuration changes — both delivered with no polling required.

Setting each one up

What it takes to use each tier.

  • Cold — request a historical export for a connection or surface, with an optional date range
  • Warm — write (or ask Azi to draft) a query, then save it if you'll want to run it again
  • Hot — subscribe to a live-stream or change-feed endpoint for the connection or surface you care about
