Why teams connect Pinecone and Supabase

Sync the records in Supabase into Pinecone and land its embeddings, classifications, and generated fields back on the same rows, in real time and without a pipeline to maintain.

AI systems do not hold customers or invoices the way business apps do. What they hold is derived from your data: the vectors and metadata in a vector store, or the classifications, extracted fields, and generated text a model produces over records it was given. Supabase is where those source records actually live. The bridge between the two is the row itself, since an item in Pinecone and the record in Supabase it describes are two halves of the same thing, and they drift the moment one is updated without the other.

Stacksync syncs Database Functions, Storage Object Metadata, Tables, Views in Supabase with Collections, Backups, Index statistics, Indexes in Pinecone in real time. Rows created or changed in Supabase flow into Pinecone so inference and embedding run on current data, and the scores, labels, and generated fields Pinecone produces flow back onto the matching rows in Supabase, mapped field by field. A change on either side appears on the other within seconds, with no extraction job or webhook plumbing to keep alive.

Because matching is by a stable identifier, every row in Supabase stays tied to its AI-side counterpart in Pinecone. Retrieval, enrichment, and generated content always resolve back to the record they came from, so there are no orphaned vectors and no labels describing a version of a row that no longer exists.

Common use cases

  • 01 Keep a Pinecone index aligned with a source of truth (a product catalog, knowledge base, or CRM) so new, changed, and deleted records upsert and delete the matching vectors.
  • 02 Two-way sync vector metadata between Pinecone and an operational database so filters and tags stay aligned on both sides.
  • 03 Consolidate Supabase project data into a warehouse for analytics while keeping the app database as the system of record
  • 04 Sync application tables in Supabase with the CRM two-way so new signups appear as contacts and sales edits flow back to the app

Common sync patterns

Keep derived data fresh as sources change

When a row in Supabase is updated or removed, its counterpart in Pinecone is updated or removed too, so nothing in Pinecone describes a record that has since changed or gone.

Backfill once, then stay in step

Load your existing rows from Supabase into Pinecone to build the index or enrichment set, then let ongoing changes sync automatically instead of re-running the whole job.

One record, one identifier

Each item in Pinecone carries the key of the row in Supabase it came from, so results resolve back to the exact record with nothing orphaned or duplicated.

What you can sync between Pinecone and Supabase

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Pinecone objects Supabase objects How this pairing syncs
Index statistics Describe_index_stats returns total and per-namespace vector counts, the index dimension, and index fullness; read to size a sync and to detect drift between Pinecone and the source of truth. Schemas Namespaces (public and custom) that scope sync access. Index statistics is specific to Pinecone and Schemas to Supabase — each maps to any object or custom field on the other side.
Indexes Serverless or pod-based containers holding vectors of a fixed dimension and distance metric (cosine, dotproduct, euclidean); managed on the control plane (api.pinecone.io) via create, list, describe, configure, and delete. describe_index returns the per-index data-plane host. auth.users Managed authentication users, often mirrored into CRM or support systems. Indexes is specific to Pinecone and auth.users to Supabase — each maps to any object or custom field on the other side.
Vectors (records) The core data: an id (up to 512 chars), a dense values array, optional sparse_values, and JSON metadata (up to 40 KB filterable per record). Full CRUD on the data plane via upsert, update, fetch, query, and delete, so write is supported here. Row Level Security Policies Row-level access rules that govern what the REST layer exposes. Vectors (records) is specific to Pinecone and Row Level Security Policies to Supabase — each maps to any object or custom field on the other side.
Namespaces Partitions inside an index; every read and write targets one namespace and vectors across namespaces are isolated. Enumerated with list_namespaces and sized per namespace via describe_index_stats. JSONB Columns Semi-structured payloads such as event properties or nested objects. Namespaces is specific to Pinecone and JSONB Columns to Supabase — each maps to any object or custom field on the other side.
Collections Immutable snapshots of a pod-based index that store its data but not its definition; created, listed, and deleted on the control plane and used to recreate a pod-based index. Serverless indexes use Backups instead. Database Functions Postgres functions that can transform or validate synced rows. Collections is specific to Pinecone and Database Functions to Supabase — each maps to any object or custom field on the other side.
Backups Point-in-time snapshots of a serverless index; created, listed, and restored into a new index on the control plane for recovery or cloning. Read as a recovery-asset inventory. Storage Object Metadata File metadata rows that can be joined to synced application data. Backups is specific to Pinecone and Storage Object Metadata to Supabase — each maps to any object or custom field on the other side.

How changes propagate between Pinecone and Supabase

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Pinecone Supabase Interval-based propagation

DetectionStacksync polls Pinecone for changes on an incremental schedule, reading only records changed since the previous pass. No webhooks and no native change-data-capture feed.

DeliveryEach detected change is applied to Supabase as a row-level write, with types converted between the two schemas.

Supabase Pinecone Sub-second propagation

DetectionSupabase pushes changes as they happen — webhook events backed by change data capture. Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime.

DeliveryEach detected change is written to Pinecone through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Pinecone: Data-plane operations are capped per second: query, upsert, update, and delete at 100 req/s per namespace, fetch at 100 req/s per index, and list at 200 req/s per index; breaches return HTTP 429. Hard request limits also apply: an upsert is max 2 MB or 1000 records, metadata max 40 KB per record, and query top_k up to 10,000 with a 4 MB result cap.
  • Supabase: SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits.

How the Pinecone and Supabase connectors work

Pinecone

Integration surface
Two HTTP APIs: a control plane at api.pinecone.io (manage indexes, collections, backups, and, via the Admin API, projects and API keys) and a per-index data plane at the host returned by describe_index (upsert, query, fetch, update, delete, list). A gRPC data-plane transport is available through the official SDKs.
Authentication
API key in the Api-Key request header, scoped to one project; every request also sends an X-Pinecone-Api-Version header (date-based, e.g. 2025-10). The organization Admin API instead uses OAuth2 client-credentials (service accounts) via login.pinecone.io/oauth/token, passing a Bearer token to api.pinecone.io/admin (Enterprise).
Change detection
No webhooks and no native change-data-capture feed. Vectors carry no server-side update timestamp, so Stacksync detects changes by re-reading - paginating vector ids with the list operation (serverless indexes) and fetching by id, or by re-upserting from the source of truth. describe_index_stats bounds a resync with per-namespace counts.
