Why teams connect MotherDuck and Pinecone

Send the records MotherDuck holds into Pinecone for embedding, classification, and scoring, and land what Pinecone produces back in MotherDuck as new columns, one two-way connection instead of a batch job.

MotherDuck holds the raw records the business runs on; Pinecone turns those records into embeddings, scores, labels, and summaries. The two meet wherever a warehouse row needs to be enriched by a model and the result needs somewhere durable to live. Most teams stitch that meeting together with export scripts and a queue, then spend their time keeping the glue alive.

Stacksync syncs Index statistics, Indexes, Vectors (records), Namespaces in Pinecone with Attached Local DuckDB Databases, Databases, Schemas, Tables in MotherDuck field by field, in real time, and in both directions. Rows added or changed in MotherDuck flow into Pinecone as they happen, and the Index statistics, Indexes, Vectors (records), Namespaces that Pinecone generates land back in MotherDuck as columns or tables, with field-level mapping and conflict rules in place of a custom pipeline.

The payoff is that model output stops living in a separate place from the data it describes. Once results sit in MotherDuck, they join against billing, product, and usage tables already there, so you can report on quality, cost, and coverage without moving anything by hand.

Common use cases

  • 01 Two-way sync vector metadata between Pinecone and an operational database so filters and tags stay aligned on both sides.
  • 02 Read an index's vectors and per-namespace statistics into a warehouse for auditing what is stored, sizing cost, and detecting drift from the source data.
  • 03 Sync modeled MotherDuck tables outward to operational tools for activation
  • 04 Share curated, synced datasets with other teams through read-only database shares

Common sync patterns

History that outlives a run

A continuously synced copy in MotherDuck preserves every generated result, so outputs stay auditable even as they are overwritten or expire inside Pinecone.

Feed live warehouse records to Pinecone

Rows added or changed in MotherDuck flow into Pinecone within seconds, so embeddings, classifications, and enrichments are computed on current data rather than a nightly extract.

Model output back in the warehouse

Scores, labels, embeddings, or summaries produced in Pinecone land in MotherDuck as columns or tables, queryable and joinable with the rest of the business data.

What you can sync between MotherDuck and Pinecone

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.

MotherDuck objects Pinecone objects How this pairing syncs
Tables The main landing target for synced records and source for analysis. 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. Tables is specific to MotherDuck and Backups to Pinecone — each maps to any object or custom field on the other side.
Views Modeled projections used as outbound sync sources. 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. Views is specific to MotherDuck and Index statistics to Pinecone — each maps to any object or custom field on the other side.
Database Shares Read-only copies of a database shared with other users or teams. 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. Database Shares is specific to MotherDuck and Indexes to Pinecone — each maps to any object or custom field on the other side.
Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries. 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. Attached Local DuckDB Databases is specific to MotherDuck and Vectors (records) to Pinecone — each maps to any object or custom field on the other side.
Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes. 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. Databases is specific to MotherDuck and Namespaces to Pinecone — each maps to any object or custom field on the other side.
Schemas Namespaces within a database used to organize synced tables. 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. Schemas is specific to MotherDuck and Collections to Pinecone — each maps to any object or custom field on the other side.

How changes propagate between MotherDuck and Pinecone

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.

MotherDuck Pinecone Interval-based propagation

DetectionStacksync polls MotherDuck for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

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

Pinecone MotherDuck 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 MotherDuck as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • MotherDuck: Subject to the platform's compute and concurrency limits rather than per-request API rate limits.
  • 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.

MotherDuck setup guide

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.
Capabilities
read · write
Rate limits
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.
