Evolve Agent Memory Schemas Without Breaking the Memory You Already Have
Agent features evolve. Memory schema needs to evolve with them. DIY memory systems break old data when the schema changes. MemoryLake handles schema evolution gracefully — typed memory adapts, prior data stays accessible, audit trail preserved.

The problem: schema changes in DIY memory break everything
You added a new field to your facts table. Old rows don't have it. Your retrieval code crashes on the migration. You bolt on a try/except. The schema "evolved" — and now you have two formats in production.
How MemoryLake handles schema evolution
Typed memory abstracts the schema
Six memory types stay stable as feature variations evolve.
Field-level versioning
Each field is independently versioned.
Forward-and-backward compatibility
New code reads old data; old code reads what it can of new data.
Audit trail per schema change
Track when each field shape changed.

How it works for schema evolution
- Connect — Use typed memory; schema mostly invisible.
- Structure — Add fields as memory evolves; old data stays accessible.
- Reuse — Read works across schema versions; deprecation handled gracefully.
Before vs. after: agent memory schema evolution
| DIY memory schema | MemoryLake | |
|---|---|---|
| Adding a field | Migration risk | Add and go |
| Reading old data after schema change | Often broken | Works automatically |
| Audit when schema changed | Manual | Built in |
| Multi-version data in production | Painful | Native |
Who this is for
Engineering teams iterating on agent features where memory schema changes are blocking velocity — and where current migrations are too risky for frequent shipping.
