Data-Oriented Features

Infinite data, sensible cost.

Vynflow's tiered storage keeps active records fast and hot while automatically archiving the long tail to a low-cost data lake — so your tables can grow without bound and without surprise bills.

Three storage tiers, one interface

Every User Table can place rows hot, cold, or move them automatically. The UI, API, gRPC and MCP behave identically regardless of tier.

Hot tier

Frequently-accessed rows stay in low-latency Postgres for real-time workflows, indexing and search.

Cold tier

Inactive rows are archived to an S3-backed data lake in Apache Iceberg format — cheap, durable, and still queryable.

Auto tier

Set an age threshold and Vynflow migrates rows from hot to cold automatically, balancing speed against cost.

Built on an open data lake

Cold data is written as Apache Iceberg tables, so your operational history is stored in an open, analytics-ready format — not locked inside a proprietary blob.

  • On-demand rehydration — pull archived rows back into active workflows with no schema rewrite.
  • Unified reads — decoded, cold-aware row reads return the same shape whether hot or cold.
  • Retention policies — keep data for as long as you need, then purge automatically.
  • Row checkpoints & soft-delete — every change is versioned and restorable.
  • Compact, hashed keys — short object keys keep lake layout tidy at scale.

Cold-tier pricing

Pay only for what you keep — billed per GB per month.

€0.20 Hot storage / GB
€0.02 Cold storage / GB

The Single Free Tier uses cold-only storage, settled from your prepaid credits.

Scale your data, not your bill.

Start on the Free tier with cold-only tables, and turn on hot/auto tiers any time.
