Why agent memory needs a lake

Memory for a single agent is a solved problem. Memory across every agent, every user, every business unit is a different problem. Scale, isolation, governance, and retrieval performance all break at the same time.

The Context Lake is the layer that solves them together. One system of record for context across the enterprise, governed at the entity level, served in milliseconds.

Across every agent. Every user.
Every source of data.

one system of record across all of it

Inside the Context Lake

Millions of context graphs, one per user, customer, team, or topic. Each captures the chat, documents, events, and business data tied to that subject — and the relationships between them — structured temporally and served back to agents on demand.

Agent Runtime

LangChain·LlamaIndex·CrewAI·Google ADK·custom

Any agent framework — or none. The Context Lake is invoked through a single SDK.

Ingestion

chat·JSON·documents·app events

Raw signal arrives from any source the agent touches.

Context Assembly

context blocks·templates·token-efficient

Relevant context is assembled on demand into token-efficient blocks.

entity extraction·relationships·ontology·invalidation

Signal becomes a temporal context graph as new facts arrive and stale ones are invalidated.

Retrieval

sub-200ms·auto-optimized·provenance-linked·policy-filtered

Selects what's relevant and what adds the most information within the token budget.

Governance

ABAC·multi-tenant isolation·customer key encryption·retention policies·audit·provenance

Native to the substrate, not a layer bolted on. Every read and write is policy-gated for access and provenance; retention runs across the data lifecycle.

Context Graph Engine

Temporal context graph with provenance — sub-200ms retrieval at scale.

Context Graph Engine

The Context Graph Engine is Zep’s proprietary runtime — millions of governed graphs, served in milliseconds, with isolation and temporality native to the data model.

A new layer in your data stack

The Context Lake runs alongside your data lake, not as a replacement. Different data, different consumers, different access patterns. Same governance rigor.

Your Data LakeContext Lake
Data

Structured, quantitative

Tables, transactions, logs, metrics.

Unstructured, qualitative

Conversations, documents, events, decisions.

Query model

SQL, batch analytics

Optimized for aggregation and retrospective analysis.

Graph traversal, semantic

Temporal context graphs with entity-aware retrieval.

Latency

Seconds-to-minutes

Batch jobs, scheduled pipelines, dashboard refresh.

Sub-200ms retrieval

Real-time context at agent inference speed.

Consumers

Dashboards & ML

BI tools, data scientists, reporting pipelines.

Agents & assistants

LLM-powered applications that need memory and context.

Governance

Row & column ACLs

Table-level permissions, role-based access.

Entity-level ABAC

Attribute-based policies, retention rules, full audit trail.

Recognition

Agent memory infrastructure for the enterprise.

We can easily see Zep becoming a de facto partner in this layer of the enterprise agent stack.

Retention policies

Retention is policy-driven. Data expires on the schedule you set. Legal hold blocks deletion when compliance requires it.
