TiDB vs. KDB.AI
Compare TiDB vs. KDB.AI by the following set of capabilities. We want you to choose the best database for you, even if it’s not us.
TiDB vs. KDB.AI on Scalability
Yes.
Yes.
Both
Neither
TiDB
TiDB is designed with scalability as one of its core features. It offers both horizontal and vertical scaling capabilities to handle growing workloads and data volumes.
KDB.AI
KDB.AI is a scalable vector database.
TiDB vs. KDB.AI on Functionality
Yes (qFlat and qHNSW)
Yes, vector search & SQL search
Yes. Hybrid Sparse & Dense Search
HNSW
Flat, qFlat, IVF, IVFPQ, HNSW, and qHNSW.
No. HNSW only
TiDB
TiDB offers vector search through its serverless cluster and supports vectors with a maximum dimension of 16,000. The Vector data type in TiDB is designed to store single-precision floating-point numbers (Float32). It only supports cosine distance and L2 distance for similarity measurement.
KDB.AI
Built by KX, a database provider known for time-series data management, KDB.AI enables developers to bring temporal and semantic context and relevancy to their applications. It supports various search types, including vector similarity search, hybrid sparse and vector search, and Non-Transformed TSS, a similarity search algorithm specific for time series data. It uses Cosine Similarity, Inner Product, and L2 Distance (Euclidean) for similarity metrics.
TiDB vs. KDB.AI on Purpose-built
No, vector search is an add-on to TiDB Cloud serverless.
Yes.
No. TiDB does not provide specific SDKs. Instead, it is designed to be compatible with MySQL, which means TiDB can be used with any language with MySQL client or driver support.
Python
TiDB vs. KDB.AI: what’s right for me?
TiDB
TiDB is an open-source distributed SQL database for OLAP and OLTP workloads. It now offers a vector search capability (in public beta) as an add-on to its SaaS solution, TiDB Cloud Serverless.
Apache 2.0
KDB.AI
KDB.AI is a powerful knowledge-based vector database and search engine that allows you to build scalable, reliable AI applications using real-time data.
