Cockroach Labs: The cloud-native distributed SQL database

Closed-source vector and full-text search service built directly on object storage, with cold queries measured in seconds rather than milliseconds.
As of 30 August 2026, turbopuffer starts at $16/month. turbopuffer keeps indexes on object storage and caches them on memory and SSD, so idle data costs storage prices rather than RAM prices. Softwr lists it under Databases.
Overview
turbopuffer is a hosted search database for vector and full-text retrieval. Its architecture inverts the usual design: instead of holding indexes in memory across a fleet of always-on nodes, it keeps the authoritative state in object storage and treats memory and local SSD purely as caches. Data is organised into namespaces, which are the unit of isolation, tenancy and throughput, and it supports dense and sparse vectors, BM25 full-text search, attribute filtering and hybrid queries. Published limits are unusually explicit: up to 128 billion documents and 256 TB per namespace, 500 million documents per shard, 64 MiB per document, 10,752 dimensions for dense vectors, roughly 10,000 writes per second and 32 MB/s per namespace, and 5,000 or more queries per second per namespace. It is offered multi-tenant by default, and also as single-tenant or BYOC deployments in a customer's own cloud. The commercial argument follows directly from the architecture. In a memory-resident vector database, cost scales with the total size of the corpus whether it is being queried or not, which is punishing for the common shape of a multi-tenant product where most customers' data is idle most of the time. Putting the index on object storage makes cold data nearly free to keep and pushes the cost onto queries and caching, which is why turbopuffer has been adopted by products with very large numbers of small, mostly dormant per-customer indexes. The published numbers are what makes this a design decision rather than a marketing one: cold queries have a p90 around 1,214 ms on a million documents, warm queries perform like an in-memory engine, and upserts have a p90 around 248 ms for a 512 KB batch because writes go to object storage directly. The buyers are engineering teams at products with per-customer search indexes and a long tail of inactive tenants. The trade-offs are latency and consistency, both documented honestly. Queries are eventually consistent by default, with the vendor stating that more than 99.8% return consistent data and that after more than 128 MiB of outstanding writes further writes remain invisible until indexed, which can take tens of seconds on a small namespace and tens of minutes on a large one. Strong consistency is available at a performance cost. And it is closed source with no community edition, so a self-hosted deployment is a commercial negotiation rather than a container image, and your contingency if the company changes direction is re-indexing your corpus somewhere else.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about turbopuffer.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Capabilities
Object storage architecture
Authoritative index state lives in S3-class storage, with memory and SSD used as caches
Namespaces
The unit of tenancy, isolation and throughput, designed for very large numbers of per-customer indexes
Vector search
Dense and sparse vectors with up to 10,752 dimensions and reported recall at 10 between 90 and 100 per cent
Full-text search
BM25 keyword search in the same system as vector retrieval, so hybrid queries need no second service
Attribute filtering
Filters on document attributes applied within the query rather than after retrieval
Documented limits
Published ceilings for namespace size, document size, write throughput and query rate rather than vague scalability claims
Configurable consistency
Eventual consistency by default with a strong consistency option per query when correctness matters more than latency
Durable writes
Writes are committed to object storage before the API returns
Multi-query requests
Up to 16 queries batched into a single request
Deployment options
Multi-tenant by default, with single-tenant and bring-your-own-cloud deployments available
Answered, with sources
Each answer names the page it came from, so you can check it rather than take our word for it.
There is no open source or community edition. Single-tenant and bring-your-own-cloud deployments exist as commercial arrangements, but there is no way to run it independently of the vendor.
Warm queries perform comparably to in-memory search engines. Cold queries, where data is not cached, have a documented p90 around 1,214 ms on a million documents. Write p90 is around 248 ms for a 512 KB upsert because writes go straight to object storage.
Eventually consistent by default, with the vendor reporting that over 99.8% of queries return consistent data. Strong consistency can be requested per query at a latency cost. Large write bursts have a longer visibility delay while indexing catches up.
Large numbers of namespaces where most are idle. The architecture makes cold data cheap to keep, which is exactly the shape of a multi-tenant product with a long tail of inactive customers.
Up to 128 billion documents and 256 TB per namespace, 500 million documents per shard, 64 MiB per document, 10,752 dense vector dimensions, roughly 10,000 writes per second per namespace and a maximum result set of 10,000.
