If you need private deployments, high performance at extreme scale, or if you have strict security requirements,
reach out to our team to set up a LanceDB Enterprise cluster in your environment.
Key benefits of LanceDB Enterprise
Below, we list the three main benefits of using LanceDB Enterprise over the open-source version of LanceDB.1. Perfect for large deployments
LanceDB Enterprise powers global deployments with a secure, compliant distributed lakehouse system that ensures complete data sovereignty and high performance at scale.| Benefit | Description |
|---|---|
| Flexible Deployment | Bring your own cloud, account, region, or Kubernetes cluster, or let LanceDB manage it for you. |
| Multi-Cloud Support | Available on AWS, GCP, and Azure. Open data layer that eliminates vendor lock-in. |
| Data Security | Encryption at rest, SOC 2 Type II, and HIPAA compliance. |
2. Best performance for petabyte scale
LanceDB OSS is built on the highly-efficient Lance format and offers extensive features out of the box. Our Enterprise solution amplifies these benefits by means of a custom-build distributed system.| Benefit | Description |
|---|---|
| Performance | Tens of thousands of QPS with latency in single-digit milliseconds, hundreds of thousands of rows per second write throughput, and low-latency indexing across many tables. |
| Scalability | Support workloads requiring data isolation with millions of active tables, or a single table with billions of rows. |
3. Developer experience
LanceDB Enterprise extends our OSS product with production-grade features while maintaining full compatibility. Move from prototype to production by simply updating your connection string — no code changes or data migration required!| Benefit | Description |
|---|---|
| Effortless Migration | Migrate from Open Source LanceDB to LanceDB Enterprise by simply using a connection URL. |
| Observability | First-class integration with existing observability systems for logging, monitoring, and distributed traces using OpenTelemetry. |
How is LanceDB Enterprise different from OSS?
LanceDB Enterprise is a distributed cluster that spans many machines (unlike LanceDB OSS, which is an embedded database that runs inside your process). Both are built on top of the same Lance columnar file format, so moving data from one edition to the other requires no conversion.| Dimension | LanceDB OSS | LanceDB Enterprise | What the difference means |
|---|---|---|---|
| Mode | Single process | Distributed fleet | OSS lives on one host. Enterprise spreads work across nodes and keeps serving even if one node fails. |
| Latency from object storage | 500–1000 ms | 50–200 ms | Enterprise mitigates network delay with an SSD cache and parallel reads. |
| Throughput | 10–50 QPS | Up to 10,000 QPS | A cluster can serve thousands of concurrent users; a single process cannot. |
| Cache | None | Distributed NVMe cache | Enterprise keeps hot data near compute and avoids repeated S3 calls. |
| Indexing & compaction | Manual | Automatic | Enterprise runs background jobs that rebuild and compact data without downtime. |
| Data format | Supports multiple available standards | Supports multiple available standards | No vendor lock-in; data moves freely between editions. |
| Deployment | Embedded in your code | Self-managed or Managed Service | Enterprise meets uptime, compliance, and support goals that OSS cannot. |
Architecture and scale
LanceDB OSS is directly embedded into your service. The process owns all CPU, memory, and storage, so scale is limited to what the host can provide. LanceDB Enterprise separates work into routers, execution nodes, and background workers. New nodes join the cluster through a discovery service; they register, replicate metadata, and begin answering traffic without a restart. A distributed control plane watches node health, shifts load away from unhealthy nodes, and enforces consensus rules that prevent split-brain events.

With Lance OSS every query fetches data from S3, GCS, or Azure Blob. Each round trip to an object store adds several hundred milliseconds, especially when data is cold. LanceDB Enterprise uses NVMe SSDs as a hybrid cache, before the data store is even accessed. The first read fills the cache, and subsequent reads come from the local disk and return in tens of milliseconds. Parallel chunked reads further reduce tail latency. This gap matters when the application serves interactive dashboards or real-time recommendations. Read More: LanceDB Enterprise PerformanceThroughput of search queries
A single LanceDB OSS process shares one CPU pool with the rest of the application. When concurrent queries hit that CPU, retrieval and similarity processes compete for cores. The server cannot process more work in parallel and any extra traffic waits in the queue, raising latency without increasing queries per second. LanceDB Enterprise distributes queries across many execution nodes. Each node runs a dedicated vector search engine that exploits all cores and uses SIMD instructions. A load balancer assigns queries to the least-loaded node, so throughput grows roughly linearly as more nodes join the cluster.Caching of commonly retrieved data
LanceDB OSS has no built-in cache. Every read repeats the same object-store round trip and pays the same latency penalty. LanceDB Enterprise shards a cache across the fleet with consistent hashing. Popular vectors remain on local NVMe drives until they age out under a least-recently-used policy. Cache misses fall back to the object store, fill the local shard, and serve future reads faster. This design slashes both latency and egress cost for workloads with temporal locality.Maintenance of vector indexes
Vector indexes fragment when data is inserted, updated, or deleted. Fragmentation slows queries because the engine must scan more blocks. LanceDB OSS offers a CLI call to compact or rebuild the index, but you must schedule it and stop queries while it runs. LanceDB Enterprise runs compaction jobs in the background. It copies data to a scratch space, rebuilds the index, swaps the old files atomically, and frees disk space. Production traffic continues uninterrupted.

When you work with LanceDB OSS, it is included as part of your binary, Docker, or serverless function. The footprint is small, and no extra services run beside it. LanceDB Enterprise comes in two flavors. The self-managed template installs the deployment inside your VPC, so data never leaves your account. The managed SaaS option hands day-to-day operations to the vendor, including patching, scaling, and 24×7 monitoring. Both enterprise modes support private networking, role-based access control, audit logs, and single sign-on. Read More: LanceDB Enterprise PerformanceWhich option is best?
LanceDB OSS makes sense when the entire dataset fits on one machine, daily traffic remains under fifty queries per second, and your team can run manual maintenance without affecting users. It’s very simple to get started with OSS: Get started withpip install lancedb and begin ingesting your data and vectors into LanceDB.
Move to LanceDB Enterprise when you have petabyte-scale data, or you need latency to be below 200 ms, or you need higher query throughput towards thousands of QPS, or your business requires high availability, compliance controls, and vendor support.
