FAQ about MyScale

QWhat kind of database is MyScale?

MyScale is a cloud-native SQL vector database built on ClickHouse. You query both structured data and vector similarity with standard SQL—purpose-built for AI and RAG.

QWhich AI frameworks does MyScale integrate with?

LangChain, LlamaIndex and more. Install our Python SDK (clickhouse-connect) and start building RAG pipelines in minutes.

QHow is MyScale different from pure vector databases?

You get full SQL power plus vector search in one system—no extra stack. Run hybrid queries that mix embeddings, full-text (Tantivy) and metadata filters in a single statement.

QHow many vectors can MyScale handle?

Billions. MSTG vector indexes on ClickHouse deliver millisecond recall and linear scale-out for enterprise workloads.

QWhat search and fusion capabilities are included?

Cosine, Euclidean, inner-product, Tantivy full-text, plus RSF and RRF ranking fusion to boost result accuracy.

QHow does MyScale secure data?

RBAC, SOC 2 Type I compliance and Telemetry for full-stack observability—enterprise-ready out of the box.

QHow do I start building with MyScale?

Sign up for the SaaS, create a cluster, pip-install clickhouse-connect, connect with your credentials and run SQL or SDK calls to ingest data and search vectors.
