Full immutable history
Each version of each row is kept — nothing is ever overwritten or thrown away.

The Vault
Schema changes that don't
break reports.
The Vault keeps every version of every row, so a source can change shape without taking your reports down with it.
The mechanism
Sources change shape. Your dashboards keep working.
Source systems inevitably change, which typically breaks downstream reports. The Vault is designed to absorb these changes automatically.
Reports survive source changes
When a source adds a column or changes a type, the columns your reports already read stay exactly as they were.
Your own computed columns
Add computed columns right in the Vault to derive business-ready values, with the source data untouched.
Roll back a faulty extraction
Restore the lake to any earlier moment, and the history stays intact.
How it works
The Vault only grows. It never rewrites.
When a source changes a column's type or adds a new one, SchemaVortex stores it as a new, versioned column. The original lives on unchanged; it just stops loading.

One table, every version: columns are only added, never altered or removed.
One table exposes every column across every version. Existing columns are never altered or removed, so the columns a report reads don't change underneath it; rows from before a new column existed show it as empty. Most systems let a column change type in place, quietly breaking the dashboards downstream — the Vault rules that out.
