Closes #18.

This picks up where #1174 left off — that PR was abandoned by its author after your review, so I reimplemented the adapter from scratch following the same overall direction and fixed all the issues the bot reviews raised there:

  • Conversation creation uses an atomic SET ... NX before indexing (fixes the TOCTOU race)
  • All pipelines go through error checking, partial failures throw instead of silently passing
  • Working-memory key construction validates the ids required by the scope
  • queryWorkflowRuns uses pipelined batch GETs (no N+1)
  • updateWorkflowState enforces id/workflowId/createdAt immutability and cleans up stale indexes
  • Message ordering uses monotonically increasing ZSET scores (same-millisecond writes kept a stable order)

Package layout mirrors @voltagent/postgres, client is ioredis, serialization uses safeStringify from @voltagent/internal.

import { RedisMemoryAdapter } from "@voltagent/redis";

const memory = new Memory({
  storage: new RedisMemoryAdapter({ connection: "redis://localhost:6379" }),
});

Data model: conversations as STRING + ZSET indexes (all/resource/user), messages as HASH + ZSET per conversation, working memory in both scopes, full workflow-state lifecycle with a suspended SET index — documented in website/docs/agents/memory/redis.md with the key layout table and RDB/AOF guidance.

One naming note: I went with RedisMemoryAdapter (implementing the Memory V2 StorageAdapter interface) rather than the RedisMemoryStorage name from the issue, matching the postgres/supabase/libsql adapters.

Test plan: 28 unit tests (mocked ioredis, no real Redis needed) — all passing; biome, tsc --noEmit (strict) and tsup build all clean. No real-Redis integration test yet; happy to add one modeled on the postgres docker-compose setup if you'd like.


Summary by cubic

Adds @voltagent/redis, a Redis storage adapter for VoltAgent Memory V2, with all review issues from the abandoned PR #1174 fixed. Closes #18.

New Features

  • Exports RedisMemoryAdapter implementing the Memory V2 StorageAdapter interface, named to match the postgres/supabase/libsql adapters.
  • Maps conversations, messages, working memory, and workflow state to Redis STRINGs, HASHes, and ZSETs with all/resource/user indexes.
  • Fixes the prior review's concerns: SET ... NX for race-free conversation creation, checked pipeline failures, scope-required id validation, immutable workflow index fields, monotonic ZSET message ordering, and pipelined batch GETs.
  • Documents the key layout and RDB/AOF persistence guidance in website/docs/agents/memory/redis.md.
  • Includes 28 unit tests against a mocked ioredis client; no real-Redis integration test yet.

Written for commit 60962c3. Summary will update on new commits.

Package foundation
packages/redis/package.json, packages/redis/src/index.ts, packages/redis/tsconfig.json, packages/redis/tsup.config.ts, packages/redis/vitest.config.mts, .changeset/*
Adds the @voltagent/redis package, public exports, build and test configuration, and minor-release metadata.
Conversation and message persistence
packages/redis/src/memory-adapter.ts, packages/redis/src/memory-adapter.spec.ts
Stores conversations, messages, and conversation steps in Redis. Supports indexing, filtering, ordering, pagination, ownership checks, batching, UUID generation, and deletion.
Working memory and workflow state
packages/redis/src/memory-adapter.ts, packages/redis/src/memory-adapter.spec.ts
Adds conversation- and user-scoped working memory, workflow state queries and indexes, suspended-state tracking, date revival, and idempotent connection shutdown.
Documentation and repository integration
packages/redis/README.md, website/docs/agents/memory/redis.md, website/sidebars.ts, docs/structure.md
Documents installation, configuration, Redis data structures, persistence, memory limits, shutdown, and repository navigation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 60962

User-scoped cleanup can delete another user's messages and workflow steps when they share a conversation, causing destructive data loss; the conversation/index failure path also remains unresolved. Merge should be blocked until ownership filtering and failure cleanup are corrected.

Use crypto.randomUUID() instead of Math.random() for identifiers.

generateId produces message identifiers that become Redis hash fields and sorted-set members. A collision silently overwrites an existing message. Math.random() gives no collision guarantee and the substring approach can also produce short strings when the fractional part is short.

Surface Redis client errors when debug is false.

The error handler only writes to the console when debug is true. If a user does not enable debug, connection, auth, and command errors are discarded with no signal. Operations then fail with generic ioredis errors and no context.

Accept an optional logger in RedisMemoryOptions, or always log client errors at warn level.

309-311: 🚀 Performance & Scalability | 🔵 Trivial

Push limit, offset, and time filters into the Redis range commands.

Three read paths fetch the entire index and the entire payload set, then filter and paginate in Node:

  • getMessages reads all message ids and all message bodies, even when limit is 1.
  • queryConversations reads every id in the chosen index before applying limit and offset.
  • queryWorkflowRuns issues one GET per execution id in the index before applying limit and offset.

Payload and latency grow with total history size, not with the requested page size. The existing key layout already supports narrower reads: use ZRANGEBYSCORE with before/after timestamps for messages, ZREVRANGE key offset count for conversation and workflow pages, and HMGET for only the selected ids. Server-side filters such as roles and status still need a post-filter, so keep a bounded over-fetch factor for those.

Also applies to: 487-488, 730-740

Add multi-user coverage for clearMessages.

Both clearMessages tests use a single userId, so they pass regardless of ownership filtering. clearMessages in memory-adapter.ts (lines 350-364) deletes the whole msgdata and stepdata keys, so it also removes messages written by other users to the same conversation. See the finding on memory-adapter.ts lines 347-368.

Add a case that writes messages for two users to one conversation, clears for one user, and asserts the other user's messages survive.

The pipeline failure simulation runs after the commands mutate state.

exec() executes every recorded command, then overwrites results[0] with the simulated error. The fake store therefore keeps all writes that the "failed" pipeline made. Real Redis would not apply a command that errored.

This weakens the test at line 375. createConversation rejects, but the assertion cannot show whether the adapter left partial state behind. Short-circuit before execution so the failure test observes an unapplied pipeline.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

A failed index write leaves an unusable, unrecreatable conversation.

set(..., "NX") commits the conversation record before the index pipeline runs. If the pipeline fails, execChecked throws, but conv:{id} remains. The conversation is then absent from getConversations, queryConversations, and countConversations, and a retry with the same id throws ConversationAlreadyExistsError. No public method can repair or replace the record.

Roll back the record when the index write fails.

The duplicate-creation test only exercises the mock's NX return path, not an actual concurrent double-create.

P2: The tests cannot validate the PR's headline guarantees (atomic SET NX TOCTOU fix and monotonically increasing message scores), because every test runs against a fresh single-instance FakeRedis whose pipeline exec() executes commands sequentially with no interleaving and no shared store. A real race or a divergence from actual ioredis command semantics (WRONGTYPE, NX behavior, score ties across processes) can never surface here, so the suite passes even if the adapter's concurrency handling is wrong. The duplicate-creation test only exercises the mock's NX return path, not an actual concurrent double-create. Add an integration test against a real Redis (the PR already references modeling it on the postgres docker-compose setup) to cover the atomic-create race and same-millisecond ordering the mock cannot represent.

P3: getMessages returns the internal StoredMessage shape, leaking userId, conversationId, and a top-level createdAt into the returned UIMessage objects. The SQL adapters return only { id, role, parts, metadata } (with createdAt nested under metadata). Construct the return value explicitly to avoid exposing storage-internal fields to callers/prompts.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Preserve other users' records in the all-conversations path.

The conversation index identifies the conversation owner. It does not identify every message and step owner. If a conversation owned by user-1 contains user-2 records, clearMessages("user-1") deletes those records at Lines 385-388.

Apply the same per-entry ownership filtering used by the conversationId branch for every indexed conversation.

Proposed fix
     const ids = await this.client.zrange(this.key("convs", "user", userId), 0, -1);
-    const pipeline = this.client.pipeline();
     for (const id of ids) {
-      pipeline.del(this.key("msgs", id));
-      pipeline.del(this.key("msgdata", id));
-      pipeline.del(this.key("steps", id));
-      pipeline.del(this.key("stepdata", id));
+      await this.clearMessages(userId, id);
     }
-
-    await this.execChecked(pipeline);
     this.log(`Cleared messages for user ${userId}`);

quick note on the latest bot round: the no-conversationId branch of clearMessages intentionally matches the postgres adapter's semantics (it wipes all conversations owned by the user, messages and steps included, without per-message userId filtering) — same story for the snapshot-then-delete flow, which is no less atomic than the SQL adapters. happy to revisit if you'd rather have redis diverge from postgres here 🙂
