Time Travel restores confidence during incidents and accelerates investigations. Instead of restoring a large backup to a side cluster, you query the database as it looked at a precise second in the past. Vela delivers this capability at the storage layer so queries remain fast and operational overhead stays low. Learn more about the approach in the How Vela Works guide and see performance context in our benchmarks.

What Time Travel means in practice

Point‑in‑time reads

Applications and analysts run the same SQL against a historical view. The result reflects the exact state of tables at a requested timestamp. This approach removes guesswork and avoids approximate reconstructions based on logs.

Bookmarks

Teams label important moments such as pre‑migration checkpoints, quarter‑end snapshots, or pre‑release gates. Each bookmark stores metadata and a stable reference you can audit later.

Branches from history

Engineers create an isolated branch from a past moment, apply a fix, and validate the result without touching production. The process takes seconds and avoids full copies.

How Vela implements Time Travel

Storage‑level versioning

Vela stores changes as new blocks while keeping previous versions compact. Queries at a timestamp read a consistent set of blocks without replaying WAL into a temporary database. The system maintains high throughput even as history grows.

Snapshot isolation at scale

Readers use snapshot isolation, so concurrent writes proceed normally. You do not pause production or throttle ingest to explore the past. Observability shows how far back you can read and how many bookmarks exist.

Familiar query experience

Clients connect with a standard DSN and include a timestamp or bookmark reference. Dashboards and scripts reuse the same connection model they already use for live traffic.

Efficient operations

Because the feature lives in the storage layer, you avoid snapshot sprawl and long restores. You keep costs predictable while gaining powerful recovery options.

Scenarios where it helps

Debug accidental deletes

A script removes too many rows. You run the failing query against the database as it existed one minute earlier, confirm the correct dataset, and restore the records into a branch for reconciliation.

Satisfy audits

Auditors request proof that a price table had specific values on a date. You reference a bookmark created at month end and produce exact results with an explanation the auditor can verify.

Run historical analytics

Product and data teams compare cohorts across months without copying production into a separate warehouse first. They query a consistent historical view and iterate quickly.

Adopt Time Travel with Vela

Create a policy to generate a bookmark before each release. Add a bookmark on migration start and end. When an incident occurs, create a branch from the relevant bookmark and validate the fix before merging. The pattern becomes muscle memory after a few cycles.
